audi 100 spluttering when hot
Hi,
Have a '92 audi 100 2.0E (AAD engine) which has been losing power over the
last few months. When cold, runs fine, but when hot, at idle, the revs creep
up to about 1200 RPM - if the accelerator is pressed at all, the engine
splutters and tries to stall. I've also noticed that the plugs and the
exhaust are very sooty. I'm waiting on an oxygen sensor arriving to try that
but I have been told that a small sensor/valve on a rubber mount close to
the metering head gives trouble. The valve has Pierburg 048 133 517 written
on it - don't have a clue what it is.
Anyone with any advice would be greatly appreciated.
Cheers,
Paul

Re: audi 100 spluttering when hot
I would look for a vacuum leak first.
Pull the codes.

Re: audi 100 spluttering when hot
I had the same issue with my TT when I first bought it. Turned out it
was the air flow meter. Just a word of caution, if it is buy a NEW one
not a used meter. It's not worth it...
