2002 A4 1.8T Farting Noise

Hi everyone,

Newbie here.

I just receently chipped(unitronics) my 2002 A4 1.8T Avant(all stock) and also upgarded the diverter valve. For some reason when driving for the 1st mile I get farting noises coming from something inside my hood(DV or turbo, don't know). It usually happen in my 2nd, or 3rd gear at 2.5K-3.8K RPM. But after a mile or so it goes away. Any thoughts?

Thanks

Stop feeding your engine beans ....LOL

Seriously, I am sure some of the turbo geeks will help you out here.

A4Avanti,

No problems, only problem is the gas leak because I'm addicted to flooring it now.

I can't seak for the APR but the unitronics really made a difference. The only complain I had is the turbo seemed to spike a lot. But I've solved that now after upgrading to the N75H valve now.
