Hi,
I know this has been done to death, but I can't find a clear answer to the problems I'm having (S3 2000, APY engine):
- Takes longer than normal to fire up from cold
- Very juddery idle
- ECU seems to have to recover from a stall whenever the revs fall to idle
- Takes quite a while to get to 90 on fast roads but fairly quickly in town
- Generally sticks at 90 once its there, will sometimes dip slightly on a long cruise
- Noticeable turbo lag
So far I've tried:
- Garage cleaned the thottle body during service a week or so back (made cold starts better but not great)
- Problem is there with/without MAF plugged in, but its worse unplugged (seems more drivable unplugged though)
- I've had coilpacks go on it before and gave much worse symptoms, so I don't think it's that, unless there's one on its last legs?
- Turbo was replaced 2-3k ago (the MAF did get caked in oil when it went but has been cleaned with contact cleaner since, which made quite a difference)
I'm leaning towards a combination of MAF and temp sensor but appreciate ideas?
Cheers
Graham
