Help wanted : Audi A6 1998 1.8T Auto stalling when hot
When the engine is hot and I am trying low speed maneouvres, the engine
stalls.
If I place the car in neutral and rev the engine and let it settle, it hunts
to the idle speed, but intitially it hunts too low. In the case where it is
in Drive at the low rev range the engine can stall.
Usually happens when pulling away at junctions or traffic lights.
This is not a problem when the engine is cold.
If anyone has any ideas please let me know.
Cheers

It was the air mass flow meter - (I think that is what they said),
potentiometer was not working.

Grem,
You wouldn't have a K&N air filter installed by any chance, would you?

Not working completely, or not working properly (I have similar problem
on different model)?

Re: Help wanted : Audi A6 1998 1.8T Auto stalling when hot
Sounds like a dirty throttle body. Try cleaning it with throttle body
cleaner. Probably a lot of gunk in there.

Filters are standard parts no K&N AFAIK.
Symptoms are still there, the air mass flow fix has certainly improved the
performance, but there is still some hunting for idle when cold but slight
improvement when hot.
The garage inform me that there are no other faults being shown on
diagnostics.
The symptoms are a damped oscilation until the throttle finds its correct
position.
My uninformed guess is that it could be a feedback a sensor problem.
Someone mentioned a sticky throttle body, I wonder if it could be
mechanical.
Thanks for all your replies.
