hEY:
I own a 2001 A4 (1.8T Q) 5 speed

When I am idling, every once and a while, the engine will "buck" when it "bucks" the tach drops about 100 rpms then it goes back to normal. It's like a hiccup!

It's botherong the hell out of me.

Any solutions or ideas?

If you have no codes and have done normal maintenance,
try Seafoaming.

 

What exactly is seafoaming?

Does this usually happen on cold starts? Can u scan and post any faults on here?

 

It does not happen only during cold starts. I have an ODB II "pocket scan" and I will try to run a test and post the findings.

Thanks a million,,,
