[tomjasz]

[johnnyfive]

I changed mine on Friday. Just printed out the TSB and "COMPLAINED" to the dealer and it was changed no questions asked. As I was told it's supposed to be some kind of high flow catalytic

[pxpaulx]

Well, at least MY Yaris doesn't stink! :iono:

[YamilR]

you have 96 month or 80,000 miles to get that corrected if needed

[Violin]

No sulfur odor but my mileage stinks. Perhaps this would help?

Is it too soon to tell if it impacted your fuel economy YamilR?

Your mileage stinks? really? how bad is it?

(sorry for the hi-jack but I'm really curious..)

[Lafiro]

Well My last, last tank was 28mpg driving it like an idiot.

This past tank I drove normal.... and only got to 31.08mpg........

So wtf is causing this? I miss the 36mpg I use to get when I first got my car.

[Violin]

I average about 30 mpg.

[Terrorize]

On 2 occasions i had a sulfur stink on my SEDAN...does anyone know if this TSB aaplies to Sedans? Heh heh it describes myt driving habit though...stop and go driving and also heavy acceleration... <-- as a result of those 2 things my MPG will never be great! :burnrubber:

[YamilR]

Before the new Cat I was getting 35mpg +/- 2. So far Im getting about the same, plus every time I go over 35mph I use the cruise control

READ THE TSB!! IT READS HATCHBACKS ONLY!!!

[Violin]

I go Thurs. morning.

[w1ngzer0]

They had the same problem/excuse with the corolla. I was reading this automechanics magazine and there was this ad for "a/c vent cleaner". I forgot where it all goes but it had this butler holding a giant piece of stinky cheese.

[nick1983]

Where do you find the tsb's

[tomjasz]

Where do you find the tsb's


I subscribe to Tundra Solutions, a toyota list that has been around for some time. Members there are GREAT about sharing PDF's from Toyota. Also a fairly large group of toyota techs that post TSB's on an extremely timely basis Tis one was posted the DAY it came out!!! The sight ia well worth the membership for us multiple Toyota owners.:thumbup:

[ChinoCharles]

Funny thing... I saw this post today and pretty much disregarded it as I haven't had the problem. Then a couple of hours ago I pulled into my friend's driveway after I went on a tear through the sticks with a Solara and sure enough, it reeked of sulfur. Can't wait for my new cat, haha. :biggrin: Thanks tomjasz.

[riceboy]

Anyone know if this applies in Canada too?

[ChinoCharles]

Called the dealership today... the service tech said he wasn't aware of any such TSB, at which point I gave him the code at the top right and he pulled it up. He was able to order the part right away and as long as the part can be sourced at their warehouse in Cincinatti I will be getting the new pipe installed next week. This is a replacement piece extending from the exhaust manifold to the axle-back exhaust, as the catalytic converter is welded directly to the pipe.

All you liftback owners, go get your replacement cat! I only smelled this after a short period of somewhat hard accelleration, but it doesn't mean the defect won't have negative effects for all cars over a period of time. Better safe than sorry, right?

Oh, and admins, you should probably sticky this.

Ah....you read my post again or use a service that provides TSB's!!:headbang:

[YarisPR]

The only strange smell i get is when working with my AirCondition specially when i lower the fan intensity :confused:

[Terrorize]

READ THE TSB!! IT READS HATCHBACKS ONLY!!!

Yeah i know its for hatchbacks only...but wondering if they will release one for sedans too heh heh...maybe same parts...well its gone now..my problem that is..i think it was just bad gas.

[Violin]

When I went in to get mine swapped yesterday, they put it up on the lift and then couldn't find the part. They have to reorder it. At least I got a free tire rotation while it was up in the air.

[riceboy]

Canada???

[jeff_o]

violin...by the way... which toyota dealer did you went to?

[Violin]

I got it done this morning at Dayton Toyota (not where I purchased). Took about 30 minutes.

[ItsMyDaily]

isn't the US liftback tank about 11 gallons???? If so then I'm averageing about 300 miles a full tank. However I fill up right when the last bar starts to blink. How long can you drive with that bar blinking?

If 300 is all I get then I'mm averaging around 28 mpg. And I drive mainly freeway, and keep it below 70. wtf!!!! And I baby the thing.

should I be concerned and take it to the dealer?

[jeff_o]

violin: i see... sorry if this may sound to be a dumb question because i dunno how warranties work here in the US.

1. if you bought a used toyota from a private seller, can you claim warranty from any toyota dealer? Or better question is...are the warranties transferrable from previous owner to you? (assuming the mileage is below what toyota advertised for the tranny, body, etc etc).

2. if you bought a used toyota from a dealer, can you claim warranty from any toyota dealer not from where you bought it from?

[Violin]

Yes. The warranty is from Toyota - not an individual dealer. It doesn't matter how many times it is sold within the warrant period, assuming maintenance records are good.

[Kitt]

I have a 2k5 Yaris and it had a strange smell but it only happened when it was new and i was using the clutch too much, when i had it on 1st gear and i was trying to drive slow @ high rpms...

[ChinoCharles]

Thats just burning clutch haha.

[bigsky2]

Just called a few service departments in my area (Lower Mainland, BC - Canada), and they are not aware of any TSB for the Yaris Hatchback 2007+ related to the catalytic converter/sulfur smell.

I think it will take some pressuring on the service department before they look into it closely. The TSB does state that it will only warrant the replacement if there is a specific complaint about the sulfur smell, so it's not like a recall.

Thought I'd try :)
No sulfur smell yet.

[Violin]

It made no difference in my mpg.

Oh well - just a shot.

Just tell them that it stinks, at least on my case they didn't do a test drive, and raise HELL if they call you a liar:evil:

[ChinoCharles]

I just got a call back from the dealership. My pipe is in and it gets installed Friday morning. Took 9 days for it to arrive. I'll post anything I hear from them regarding the subject.

[kty75]

hallo all.
i am from Vancouver BC
just brought my car to do the first service today
and i mentioned this problem
however, they will change the muffler part for me.. :)

[ChinoCharles]

Got mine replaced. Nothing noticable, and I haven't smelled that god awful stench since. Eww.

[YANGSTER]

Went to the Dealer today, i told the service manager i have the part number if that's gonna help him to find it out the problem faster....reply "we need our guys take a look first, different cars might have different problem." okay...fine. My friend who happened to be a tech working @ this dealership tonight (i've no idea before i went), mentioned the TSB...he went back and checked their computer.....yeah, the TSB is applicable in Canada too. the part costs about $860 CAD...no wonder the manager didnt want to listen at first place. Guys....Go nuts with this TSB!

[Black Yaris]

I am wondering if those of us with the Megan header are still eligable for this?

[ChinoCharles]

Read your warranty rights guide and find a spot in writing that says they have to honor the TSB. I'm sure its in there.

[mcstarbucks]

obviously they probably corrected this problem by installing the new part at the factory for the current production run. Question is, when did they start installing the new part at the factory? I purchased my Yaris 3 weeks ago, and I am wondering if new part has already been installed.

if you have read the TSB, you'll find TOYOTA still uses the old part in production....They'll replace the part ONLY if u complain.

[ChinoCharles]

And for that reason, GO COMPLAIN! The TSB even says the replacement piece has a higher-flow cat. It adds .3 HP! :tongue:

[Pars]

Cool. Now I know there's a fix for that particular problem and it wasn't my imagination. I wonder if the problem is isolated to us manual equipped enthusiast with lead foot. :rolleyes:

[mcstarbucks]

what will the effect of the new part be on gas mileage? If it is negative, might not be worth complaining about.

[ChinoCharles]

Hahaha, if there is any change it would be so small you wouldn't even notice.

[YamilR]

I changed mine on Friday. Just printed out the TSB and "COMPLAINED" to the dealer and it was changed no questions asked. As I was told it's supposed to be some kind of high flow catalytic

Well the smell is back again, it usually comes during start up thru the A/C vents and last for a minute or so. I will contact the dealer and see what happens. Any one else with a recurring problem?

[Violin]

Knot eye.

[ChinoCharles]

I haven't had an issue since I got the part replaced.

[Niseiwerkz]

Yeah ive been having the same problem for a few weeks now. Im a little confused on whats causing it. I thought it was the in cabin air filter was dirty but it wasnt that.

[yuiedie]

ive been experiencing a very strong "odor" that occasionally creeps up when changing the ac from hot/warm to cold/cool. In the morning its cold so i turn up the heat, and in the afternoon it gets hot, so i turn up the ac to cold. i figured that was what was causing the weird smell. kinda like coolant. once in a while a distinct sour smell but only sometimes, and this happens when starting the car up during warm weather with the ac on (cold).

[IsLNdbOi]

I've had this problem since I got my LB back at the end of August. Some mornings when I startup and when I get on the highway, it gets really bad.

How long does it take them to change the part?

[mygfdrivesayaris]

This sulfur smell is caused by the honeycomb like material inside the catalytic converter getting too hot - this is usually caused by driving and economy car like a race car - ease up turbo and the smell will go away, otherwise drive fast and enjoy the fragrance. ALSO - For the guy who asked on page 3 - Your low fuel light starts to blink when it is about 9.5 gallons low so the mileage should be closer to 31.58 MPG - that being said you can technically go 47.36 more miles after that light comes on, but i would fill up instead.

[jetaimejsc]

i just got my yaris like 1month & 1/2 and everytime my girlfriend gets in she always complains abou the smell, shes like "man, it stinks in here" but when she says that i assure you i did not fart, maybe i did but i doubt it, but i got allergies year round, so i cant even smell my upper lip, can ya explain to me what it kind of smells like, and should i get it checked, once a while i can smell something and it stinks pretty bad after like i went pretty fast

[the_boss]

I smell a little but I can't say if it's the car or the paper mill...:confused: will have the car check just in case!

[ChinoCharles]

There is no reason not to go in and have this change made on your vehicle. There is obviously a problem with the stock setup, as Toyota wouldn't bother putting out a TSB on the issue if they didn't see the need to fix things. In short, don't ask questions or wait to smell anything. Just go into the dealership and say I want my catalytic converter swapped out for the updated model according to TSB EG035-06. Your dealership might even be impressed that you pay such close attention! Note: This is for liftbacks only.

[the_boss]

any one know if it's US model, North American model or?
I just remember my old echo (2001..) was smelling like sulfur:iono: maybe there where an issue with those model too

[IsLNdbOi]

How long does it take them to make this change? Couple of hours?

[YamilR]

45 min. on mine

[jouslee]

does it matter which dealership i goto or do i need to go to the dealership that i bought my car from?

[IsLNdbOi]

I just called my dealer and they said I have to leave my car there for at least 3 hours so they can find out what is causing the sulfur odor. I told them I had a printout of the TSB, but they said just because there is a TSB it doesn't mean that the odor is not caused by something else.

Don't all dealers honor Toyota's standard warranty? If you're in it you should be able to go to any dealership you want until you find one that will change it without being dicks about it. My dealership did it no questions asked, as they all ought to.

[BMGYaris]

Yea, if yo usay that you smelled sulfur during heavy acceleration then they cant really say "no you didnt" also there is no way to prove that it wasnt the catalytic converter that did it. Thus it would surely fall under the "specific complaint" category and if you ask them to change it then they really can not deny you right? regardless of what they may think caused it. Unless they can prove it didnt:) can they do that?

Also, will this improve heat flow? I found over the winter that the heat sucks. They are so far away that by the time the actual flow of air hits me its not warm. That means in the winter I cant drive with my windows down and heat on full and stay warm:) which i love to do

[Jerkratt]

you know my mom used to have an 01 camry.. and it had this problem and everytime i went and asked about this smell they said it could eb the type of gas im putting in. needless to say i know it was not but anyway im going to see if i can get this done

[IsLNdbOi]

I finally brought mine in today for this. They're going to keep my Yaris at least overnight. They had to order the part(s).

[the_boss]

just called my dealer...they said the don't check tech service bulletin untill they have a complaint:eek:
I guess Ill take care of the maintnance by myself:cry:

[Shroomster]

so this tsb is still relevant for those of us with a lb produced after january of 2007?

[IsLNdbOi]

It's been almost two weeks since I brought mine in for this. The sulfur smell is gone, but now there's this really strong smell that's similar to a chemical cleanser. Not sure what it is, but it only happens in the morning when I first start up or the first time I get on the highway on a day.

[Sabretooth]

Will the dealership have a fit if you have modded your Yaris? Example: CAI?
Dont know if they will honor the TSB, seeing that it effects a complete opposite end of the car, but in-advertantly is effected by it. More in = more needing to go out?

Is that smell comes when you turn the A/C on? I had a bad smell after I changed my cat and took it to the dealer, they said it was mold on the a/c ducts, they put some kind of foam cleanser and it worked pretty good

[the_boss]

had mine done today...30 minutes.....0$:thumbup:

[Toyotech]

+1

they won't have a fit... the only issue they may have if your throwing a P0171 lean code with the intake and its due to an incorrect install. if its a good dealer...they will never even take it into consideration

[squibby]

hey i've been reading a lot on these forums and do also get the sulfur smell in my car. I took it in today and complained about it, but the dealership said that Toyota dosen't honor the tsb in California anymore because of something in the gas. Is this true? Has anyone recently gotten theirs changed in CA?

Have not heard this yet. Sounds pretty suspicious. Which dealer? Where/how did he get this info? Ask to see it in writing. Calll Toyota Corporate. At this point I would not believe him. Possibly Toyota is losing $$ on this big time and now doing an about face and "blaming" it on the gas addititives?

[squibby]

It was at Elk Grove Toyota up near Sac. He said they got an email from Toyota saying not to change anymore cats for the sulfur smell. I thought it was strange too, but the service manager wasn't in yet so I just got his number and left. I've already emailed Toyota, but I'll call Toyota Corp after work if I don't get a response by then.

I was very interested in this and had a few minutes so I called Toyota Corporate. They researched it for me and assured me that they are still replacing catalytic converters as stated in TSB EG035-06 (Revised). Your dealer who told you that he received an email from Toyota stating not to change it is probably making that up. I would go with what Toyota says. You can call for yourself. If in fact the dealer is being less than honest with you, I would raise some hell and let his "bosses" know about it. Good luck!

[mushrmboy]

does this apply to recently purchased yarii too? i just got mine 2 weeks ago and i'm wondering if they would have replaced the part on their own by now. and how bad is the smell? so far i haven't been able to smell anything, but i haven't been in any real stop and go traffic yet. :iono:

I'm pretty sure it applies to new ones because I just got my yaris about a month or so ago and it's got the problem.

It smells really bad like rotten eggs. I don't even think you need to be in real bad stop and go traffic for it to happen. The first time I noticed the smell was after driving back to Sac from SF with pretty light traffic. I started my car after dropping off my brother and it was rotten egg smell all over.

Thanks jlift. I'm going back there tomorrow to let them know I've talked to Toyota Corporate and got confirmation that the TSB is still in effect. If they still won't change it, then I'll be raising hell with the managers. :evil:

Yes. They are actually NOT putting the replacement Cat. on newly manufactured Yarii as they roll out of the factory. But, if you are aware of the TSB and print it out and take it in to them (you'll find it in a .pdf at the beginning of this thread), then they must honor it. Only if you are aware of it and ask for it, then they will replace it. I think that Toyota is trying to be "cost effective" here. i.e., what you don't know won't hurt you. (believe me, a majority of car owners do not know about these technical service bulletins!) It's best to have a copy of the TSB so that they can't say, "well, maybe you got some bad gas or are smelling something else" or something else like that. When I got my work done, I went in with a stack of 4 TSB's! The service rep. told me that I was not his "average" customer.:thumbup:

[hans_fh]

Okay. The sedan doesn't have this problem, right?

[jlift]

Okay. The sedan doesn't have this problem, right?

No. The TSB states:

"TSB REVISION NOTICE: August 4, 2006. This TSB applies ONLY to Yaris liftback models."


So we are talking about the liftback here. Sorry for any confusion. The TSB's state exactly which models are affected on any specific upgrade. Which begs the question, "why are the sedans unaffected? Perhaps they have the newer part on them?" hmmmmm....

Thanks a lot! It seems there is no any TSB talks about Yaris Sedan except the Rattle in Reverse. Am I right?


Well, there is TSB NV009-06 which deals with Upper/lower windshield tick noise which I posted on this forum.
But this applies to 2003-2007 model year Toyota vehicles and 2004-2007 Scion so I think that the 07 sedan would be included.

That's about the only other one I am aware of that would be for the Sedan. Search on "TSB" on this forum and you will find it. The dealer will let you know what specific TSB's are out there for your car if you ask him. It might be worthwhile thing to do next time you are there. You could also search on a website that has them for a fee and you can get the TSB numbers as a reference. I think that tundrasolutions.com/forums will let you see all the way up to the title of the TSB, in their knowledge base in the yaris forum.

[eTiMaGo]

As for the cause of this bad smell, I though I had posted thins before, but this is what I noticed, as I have a basic AFR (air-fuel ratio) meter.

When you drive normally, the ECU keeps the AFR oscillating around the standard 14.7:1, going lean-rich-lean-rich... This, apparently, is to enhance the efficiency of the catalyser.

But, when you step on it, the ECU seems to make the AFR very rich, I've seen it go up to 11:1, and stay there, which is a lot of fuel, a lot of which will go unburned, and this seems to mess with the stock catalyser, hence causing this smell. The theory behind this extra fuel is that it will help in keeping the engine cool and prevent detonation, as would be done when you have a turbo, so it's really a safety measure for engine longevity.

I guess the new catalyser is better able to contain or process this extra fuel so that it does not cause the stink...

I don't know if this TSB is also available here, never bothered to check... I just let off the accelerator a little when I see this extra-rich AFR...

[death is my gift]

I am having the same problem (didn't know this thread existed cuz i'm a dumbass). I just called the services department of my dealer. I specifically said, "excessive sulfur odor" and right away the dude said, "Bring it in tomorrow so we can have a look at it." I didn't say I had a print out of the TSB so I'm sort of curious on how they will handle this. If they give me ANY crap I'm going to whip out the print out and be all, "SUCKAH!"

So, I'll let you guys know.

[sherryberry]

i think there is a strange sulfur smell on mine but i don't sniff sulfur on a regular basis so cannot be completely sure. Just that there is a strange smell. so do I just go to the dealer to fix this?

[Christopher]

'07 Hatch here. No smells, 36-38mpg driving 50/50 highway/city (well over posted limits-lol) with the A/C pumping. So far so good. About 7 months old and 5100 miles on it. Chris

[azncharm]

Went to the dealer last month with TSB print-out and they ordered the part. No questions asked. Called me back after a week and replaced the catalytic converter in less than an hour. However, I can still smell it sometimes. Less often than usual but it still happens. Before, it usually occurs in the first 3 minutes when I start the car. Now it smells less often and when Im about 10 minutes driving. Still observing. If it doesn't go away completely I will go back to my dealer.

[death is my gift]

So I went to the dealer and dude crawled under my car and said it was a plastic bag that had melted to my whatever-it's-called. I didn't believe him so I crawled under there with him and told him to show it to me. Sure enough, he was able to scrap a bit of it off with his ink pen. I asked him what I should do and he said either let it burn off by itself or take it to a "car wash" to have them scrap it off for me.

I then showed him the printed out TSB and he said that wasn't on "all" 2007 Liftbacks, just some. I told him I wanted it changed anyway and he said they could evaluate it (whatever that means) and if they don't find a reason to change it they would charge me 70 bucks for the evaluation. But, if they did find a cause to change it they would do it for free. I told him I would wait and see if the smell went away.

What do you guys think? Are they obligated to change it even though he said, "Not all '07 Liftbacks were affected?"

[Jerkratt]

get a car wash and have them clean it then go to a diff dealership they will do what ever they can to not do the tsb cause they lose money. there "eval" is bs but thats just me.. id say if u lived closer i can get one of my friends at the dealer by me to just be like yeah blah blah blah and order the part but ur kinda far

Yeah, that sounds like a BS excuse. The TSB says Liftback, NOT some of them

[xerophinity]

Oh man, where would I be without this forum. I was in a crash in my friends Honda once, and it's the same smell as when the Airbags deployed. At least now I have a chance to make it go away, hopefully Whitby Toyota aren't dicks and they won't try to jerk me around.

edit: Okay so I gave Toyota Canada a call and they want me to take it into the dealer to take a look at it first. I have a feeling I'm going to get inroduced to that evaluaton fee you guys were talking about... Here I was hoping for just a take-it-in-have-it-replaced-no-questions-asked kinda deal, but I guess they're just not going to let this go without a fight.

Strong Sulfur smell?

Eat. More. Fiber.

i had mine replaced 6 months ago left the dealed got it on the fhy wide open still smells like shit and toyota says there is no problem this has had the bad smell from day one mine is a 08 model year but built in 07 im lost on what to do next ? from what i have heard is the smell comes from the cat when its working not when its not working they say that the car is dumping to much fuel in the motor i need the ecu reflashed with some changes but toyota does not have a program for the 07 model year anyone have the true info on this matter

[detroiter]

Don't feel bad. Mine does the same thing when I nail the gas at wide open. Mine is an 08 LB that's white colored too :)

The dealer pretty much told me the same as they did to you, that it's just all the extra fuel being dumped in running rich, then burning off. Told me that it's a "Toyota smell".
I guess I can see where there coming from, kind of like how Fords at WOT smells like eggs and fruit punch lol.

[silver_echo]

what i noticed when i had my 01 on the dyno is that the factory fuel map makes it too rich at WOT... i get the same smell as well...

[pennyracer]

thats wild the same problem did you get your cat replaced detroiter
? my concern about this one am i getting worse gas millage then normall ? if so its costing me extra money witch would be b.s. in my book 2nd thing is this going to lead to major build up on the valves and plugs down the road ? yes toyota was zero help on this deal wish i could get some answers someware

[detroiter]

Nope they didn't replace anything. They tried selling me off that nothing was wrong, that the strong smell when you hot dog the accelerator is just a "toyota thing". Smells like a sulfur or burning stench. They were not much help at all so I might try and go to a seperate Toyota dealer and see what they have to say.

[BLAZINBLUEVITZ]

Yeah, that sounds like a BS excuse. The TSB says Liftback, NOT some of them

not true, it does give a VIN number cutoff point so not ALL liftbacks are involved.....

[AlexNet0]

I get the smell if I hold it through more than 2 gears, etc 1-WOT 2-WOT, start 3rd at WOT and I get the smell.

I assume this is becuase the cat heats up

[Jerkratt]

on my 08 i have the nitto mid-pipe.. and i get the HOT SS smell.. lol ALOT better then the sulfer smell... when i HAD my 07 i got it replaced and the smell was still there... but not nearly as bad/much

[pennyracer]

i just had a idea i wonder if i buy a older ecu than mine if this would correct the problem since it seems to be dumping to much fuel and i hear there is no re flash for the ecu on the yaris to this day anyone have some good input on this idea ?

[Jerkratt]

dont think so.. things wont line up right with the connectors u would have to rewire it

[helphelp911]

Does this TSB apply to canada too??

I have read the TB on sulfur smell in 2006/07 HB. I have a 2008 that exhibits the same odor after deexceleration from highway speeds. At first I thought it was from a vehicle in front of me. Yesterday I was traveling 75 mph passing a truck and let off the gas and noticed the odor. The AC outside vent was closed, The windows were rolled up and there were no vehicles in front of me. There was no human injected fumes either. Is anyone experiencing this and is there any ideas on how the fumes are getting a closed vehicle?

at times we can smell the plastic manifold coming up from under the hood into the fresh air intake and through the vents of the cabin while climbing steep hills under a strain . Kind of smells like oil that gets on engine from forgetting to put oil cap back on or spilling of oil onto motor during oil change . When 1st bought a YARIS this happened when climbing a very steep hill . So pulled off to side of road thinking I had left oil cap off ( or loose ) after doing a oil change . Lifted the hood to find not to be the case , so followed the odor to the plastic manifold ( TUCAN SAM :rolleyes: ) . Seems to be more present ( stronger ) when the car is newer .

[bobalou1]

I just got back from the local dealer. I Took my car in and explained the problem to the service advisor. He said they would have to duplicate the problem of sulfur odor. I printed out a copy to the TB, as recommended by other Yarisworld
responders. He read the TB and said when do you want to make an appointment to get it taken care of. Tomorrow 08:00 and it would take about an hour if they have the parts in stock. This only goes to prove that you need to take a copy of the TB with you. Will keep you informed.:iono:

[Twistoffate0817]

My 09 hatch stinks whenever i turn the heat on! Smells horrible..is this the problem?

[bobalou1]

I have finally heard from the dealer and Toyota approved the Cat swap on my 08 Yaris. Parts are on back order nation wide indicating there is a bigger problem than just with the 06 and 07 models.:iono:

[bobalou1]

The smell in my case has nothing to do with the heater. During deexcelleration the air in the car is filled with the smell of rotten eggs. It has to do with the Cat Converter.

My car has the smell when wialaing onto the highway in 2nd and third. My gas mileage is alos down to 33 from 38. I called toyota customer care and got a case number and they said the dealer would replace the exhaust system ( from the front header all the way to the rear muffler is in volved in this TSB). Th edealer said they couldnt duplicate the smell. I said I smell it periodically, and exhaust SHOULD NOT BE coming into the car when its moving 70 MPH! The TSB says replace it if the CUSTOMER complains about sulphur odor. They will do nothing. Must be too busy fixing gas pedals.

Hi- did you get it fixed yet ? and if you did have U noticed any improvement to power, sound or gas mileage? I guess it's the whole welded exhaust from the header exit to the muffler entrance that gets replaced. Expensive part!

[bobalou1]

Dealer is still waiting on B/O parts.

Hi All,

Could you please direct me to the TSB? While I have not noticed the smell while driving, I have noticed the smell while the car sits idle and I am outside of the vehicle. (like clearing snow, getting something out of the hatch, etc.) I am in Canada if that makes a difference. I would really like to get this taken care of.

Thanks!

[zachryboles]

look at the first page its the pdf

Thanks! Most all exhaust will have some odor near the exhaust outside the car - or may be noticed whilst reversing into a spot with a side light open. This is not a problem - just an indication of how much sulphur there is in the fuel you are using. Yes, fuel is loaded with sulphur compounds. You will find no remedy with this TSB and waste time in agony at the dealer.
