Hi folks.... OK I know My way around A fair few VWs, the S4 I've conquered, but now Im trying to learn about TDi's.... I recently got a non PD A3 110 Tdi 98.
I want to make it run at its best before I get it mapped. SO Ive been storing up info as I go. This afternoon I was going to test if the Dielectric grease on the maf makes any difference. Ive seen some feedback that it works well, I wanted to test that and have some conclusive proof. MOre on that later.
Other things Ive read about TDis that need to be tip top...
MAF(you can use VAGCOM to check)
EGR ( you can pysically check)
Boost pipes( Im gonna make a Intake pressure tester like I did for the S4).
Anything else?
Now..... S4 owners use VAGCOM to monitor certain groups in the ECU to tell if its happy or not and do "FATS" times(For the Advancement of The S). Basically it times how long it gets from 4000 to 6500 revs in 3rd.... Owners then can compare times and see what differences what mods make to their cars without using rolling road....
So I thought Id create a benchmark and try a FATTOB time ( For the Advancement of The Turbo Oil Burners )
SO I chose the rev range 2000 to 4200..... I'll post another post when Ive finished and done the FATTOB spreadsheet etc etc... any way....To the Point of this post:
Anyway I did some testing and noticed that at full throttle the Throttle position sensor never reads more than 90%..... That obviously isnt great so My question is.... where is the sensor and how so I adjust it? I havent looked yet as the weather is miserable........ so I thought Id post....
Thoughts?
Cheers.
