Hello all,
It seems I'm having a lean condition only in bank 2. I'm thinking maybe it's the upstream 02 sensors? I'll climb under car on weekend and peek to see if I can find where these are located on my 3.0tfsi.

Anybody else have this problem before with helpful advice?

I found a very useful thread but it was for an A8. Since I'm still learning about these cars I have no clue if these diagnostic suggestions would help me on my problem as the culprit was one of two fuel pumps. Does the A6 have two fuel pumps?

thank you.

Update: My lean condition has improved. Apparently this issue was related to the fuel rail recall. Problem corrected itself to acceptable values after I got car back from that service.
