I wonder if anyone can help. I have a 97 A3 1.8T sport. After I have
driven the car for approx 20 mins at motor way cruising speed the
engine starts to misfire, it gets so bad I have to stop the car and
let it cool down. However the story doesn't stop there, if the outside
temperature is below 2 degrees the car rarely misfires.
I took it to my local Audi deal, they connected it to their computer
and told me that it required a new throttle body. So they duely fitted
it, this did not fix the problem. That was 3 months ago, to date they
have not been able to diagnose what is wrong, as every time it happens
and I take it to the garage, one, the car behaves and two, there are
no error codes stored in the computer.
Help!! Any ideas?? I thought about replacing the coil packs, what do
