30K throttle service

[jaggurnaut]

I just put 30K on my Yaris and took it in to the dealer for the 30K. Just got a call about a $60 throttle service (remove carbon) and a $30 air filter sensor service (will have to buy air filter sensors at 50K if service not performed). The 30K service costs $290. What do you guys think? Am I being overcharged and is the service necessary.

My yaris is a manual driven in mostly hilly areas. Its a commuter car and I absolutely need it everyday.

Thanks in advance for all your help.

i thought they cover everything when you take it into them?? i got the complete package, I figure if there is some kind of service they think is necessary and its still under warranty, shouldnt they eat it???

[-m-]

Pretty sure they'll get out of it by calling it maintenance. When I got mine the dealer told me that I have to do required maintenance on the car or my waranty will be voided. They are talking about the oil changes but I'm sure they will figure out something else to call maintenance and charge me for it sooner or later.

I may be wrong on this, but I thought we had 100K miles before a tune up. What the hell is this crap they are trying to pull?

Does your car still perform properly with decent MPGs?

Dealer$hip$ do love the $ervice package$ though.

I thought it was 100K before any service but the guy at the dealer said that there is a 30K service.. So not sure about the 100K service rumor?

I am sure those are things that you can do yourself and if they tell you it will void your warranty if they dont do it then they are full of it. Unless you blow something up.

If it worries you much, and its seems like a scam....go to a reliable third-party repair shop. I know I will be doing this because mine are reliable, just only thing is...they dont use synthetic oil for oil changes and replace old filters w/cheap filters.....

what are you talking about? I don't know of one shop in my shit as town of Toledo that changes oil, that the minimun is sinthetic blend, and full synthetic is avalible everywhere..... what island do you live on where there is no synthetic oil?

The throttle body service is an easy DIY. Air filter sensor??? Do they mean mass airflow sensor (MAF) cleaning? This can also be done yourself... Just research it, their both very easy with the correct cleaners.

Dude, most shops in my area use conventional oil by default as well as the cheapest filters known to man. Engine problems ARE their bread and butter you know. 3000 mile conventional oil changes are also money in the bank for them.

thats bullshit they're overcharging you. especially since u can do it yourself

Dude, there are repairs shops out here that do oil change + filter for like $10-$15, use the cheapest brands they can find to drive in business for other repair work in the future. Kioshi and I live in Cali, i am sure we have a good supply of synthetic oils on hand at these repair shops, but thats where they get you they price synthetic oils as if they were liquid gold. Toyota Dealerships out here are the same $20-$30 oil changes and they use conventional oils, we should all move to toledo for the royal treatment
, but back to the question at hand, most of the repairs they offer are an easy way to get some money from you, i would go to a good repair shop and pay half the price, for the same service they are recommending.

Like Pavel said, if it isn't in the maintenance schedlue that came with your car originally, then it simply can't void your warranty. There are two maintenance schedules: the Toyota one, written by and for Toyota, which will preserve the life of your car, and then there is the dealership's recommendations, which are specifically designed to ilk your hard-earned cash away from you. There is nothing that your dealership can do as long as you follow the Toyota factory maintenance recommendations. Easy as pie.

thanks for the back-up nsmitchell ^_^. Black Yaris ya gotta understand.....each state's different and each state's got their own way of doign things. And not to be racist or anything...even though the majority of my friends consist of asians......

Theres A LOT of asians opening up repair shops where I live...and if theres one thing you know about them, its this: they'll use whatever inexpensive method to get the money they need and make it somewhat half-assed decent work on a car, boat, or anything. Trust me, they wouldnt want to waste their money using synthetic oil on cars THEY dont drive or care about~

Nonetheless....that repair shop saved me from other corrupt repair shops so...there still pretty good. I may end up doing oil changes myself to go synthetic.

i do a throttal body service EVERY 15 k on all my vehicles due to carbon buildup mostly because of the crappy gas now days, carbon is a byproduct of the combustion engine their is nothing u can do to prevent it and yes it is maintance. carbon stops up ur iac valve that may cause a searching idle condition and sometimes a no idle condition also a throttal body service helps the engine overall preform better it is also very easy to do yourself as for the air filter senser they are talking about cleaning the mass air flow senser are dealer does not even sell this serivice but keeping t clean can only help the maf read more accurate u can by the cleaner at a part store also.

the only way ANY car manufacture can void a warrenty is to directly prove ur modification or in this cace what u didnt buy caused the failure directly without a dought so in my opinion no thay cannot void ur warrenty.

are cars have 100k plugs and 100kish coolent depnding on conditions where u live.
sorry for the long post lust wanted to give accurate info

Maybe a stupid question but.....I thought only incoming air goes thru the throttle body or MAF sensor???? Not sure where the engine bypass vent tube goes (think it's downstream of the TB and MAF also) but the oil trap DIY would stop most of that. So aren't we really talking of the crap buildup from what gets thru the air filter....so cleaning is rare necessity with proper air filter replacement????

Edit: Hate to say it but having an oiled K&N filter would possibly add contaminates!

[Toyota Technician]

only incoming air goes through ur maf but incoming air and recirculated air goes through ur tb. the pcv system (positive crankcase ventilation) recirculates blowby gas's, the gas's that pass the piston rings on all cars with a combustion engine witch contain carbon then are recirculated through the crankcase, eventually to the valve cover then are dumped back into the intake boot befor the throttal body and in turn clogs the tb. Have u ever wonderd why ur oil turns black well that is the main reason.

i dont see no reason y a oil catch can would stop particulant matter from passing through to the intake unless it has a dense filtering material in it?

a airfilter does not catch all particulant matter it only filters down to so many microns then anything smaller goes right through the af so y couldn't the maf get dirty and knowing that a maf sensor is a variable resistance type of sensor if their was dirt or anything els on the maf could that not change ur resistance value and cause the maf the read incorectly.

The blowby gasses are carbon rich true...but mainly oil picked up by the hot gasses as they go thru the oil coated rings or thru the valve seals. One of the posts on the oil catch can stated a sizable quantity of oil collected in 500miles!

Oil was the main air filtering agent for the 1st half century of the automobile (until the mid 50's) along with a metal screen that kept the bugs and rocks out of the carburator....not nearly as effective as todays filters, but they worked.

Basically I'm just stating that an oil catch can and the largest area, smallest micron filter you can use could "reduce" the need to clean the MAF or TB. I've driven cars with well over 200K on them that ran fine and never had them cleaned...preventive maintenence is key.
