High Mileage Maintenance Tips?

[AdamDavis]

Hi all, 4 months ago I bought a diesel yaris on an 07 plate here in the UK with 144000 miles on.

Anyway the car seems to be running fine, however the service history is dodgy to say the least so I replaced the air filter, pollen filter and most recently the fuel filter for the car and I found them all to be very dirty/clogged so a bit of neglect seems to have happened with previous owners. When I bought the car, a new turbo had been put on and the oil and filter done.

I'll be taking the car to a local garage in a couple of months and having them do a coolant change and the oil and filter on the car, but I was wondering if there is anything else I can do to help get the most life out of my car as possible, as I will be driving it about 2000 miles a month just for work. I have read about cleaning the EGR valve as carbon builds up there, but as I understand it is not as easy on the 2nd generation Yaris's compared to the first as I can't even see the EGR valve at the moment.

So is there anything else I can do/ should keep my eye on, to make this car last to 200,000 miles (3ish years) at least?

(PS. Most of my journey to work is motorway driving so I'm just going to be sat in 5th gear at 70-75mph most of the time. Oh and I put on new front brake pads.)
