Hey guys I've got a 98 a4 quattro 2. Over the past couple months I've noticed some shaking at idle, not really crazy but enough for me to notice.

Check engine light has been on for a while, due to one of the secondary o2 sensors post cat. Recently, the car has had a really rough time staying running at cold start. Rpm's jumping all over, a little bit of smoke for a few seconds at initial start as well.

Not oil smoke tho. It has cut out a few times as well. Runs a little smoother as it reaches running temp except for the shaking i mentioned. So I had a buddy look it over with vagcom. Got some interesting codes. Do you gain access by removing the battery? No, you might have to take some of the intake tubing off to get to it. Its a PITA to get to it. You get to it just like the Bank 2 side. You just have to move what you need to get to it. Are you getting codes for oxygen sensors?

Why are you replacing all 4 sensors? Parts dealer strongly recommended changing out all 4 sensors since car has k miles on it.

Claimed they slowly burn out by this age causing drop in performance and MPG. We'll try to gain access to bank 1 sensor 1 the one cited in car's error code message anyway possible in the morning.

Too bad Audi engineers didn't provide a back door to get this normal repair done. Please login or register to post a reply. Sponsored links.
