    I just changed the plugs(wires had to be ordered), and its running much better, but still sputtering on acceleration under 2000 rpms, at idle its fine. I think it might be an exhaust leak but not sure. Looking for exhaust leak, I found trans fluid leaking(drops). could the sputtering be the trans? Going to try to bring it to Aamco.

    oil pressure light flashing on my 2002 Audi a6 avant 3.0L. I'm guessing its the oil pressure because my oil level is low and its not decreasing. I ran the codes and the only 1 showing is a coolant sensor code. Anyone having similar issues?

Most of these codes are related . and caused by the other codes . my suggestion is to do a tune up and clear all the codes and drive and see if your check engine comes on again . i am rather sure the tune up will do the job.
later paul

How do I re-set the service indicator on a 2007 Audi A6?


It is not possible to have that reset or turned off "Service Due!" without using a diagnostic scantool connected to the data link connector of the car. This is the only one way to reset service due light on a 2007 Audi A6.

AUDI A6 Quattro Avant 1999 2.8 Radio code VIN:WAUDA24B6XN069002


Radio lock out codes are security related and where supplied with the original paper work when the car was delivered to the original owner to discourage theft, so they are not published on the web, if they were what would be the point? Any thief could get the code after stealing your radio.

Contact the dealer for instructions and what info u need to get your cars unique radio code. The dealer will require the serial number off the radio and proof of ownership of the car it came from.

Hope help with this.

1999 AUDI A6 avant 2.8L quattro. Car vibrates


This is a manual transmission? If so the clutch probably needs to be replaced. When you say "VIOLENTLY" what is going on, what is the road speed, what are the RPMs at? The more specific information the better. And this problem ONLY occurs between gear changes, right? The other times, everything is normal?

I just bought a 2005 A6 4.2 Quattro


In my A4, it's on the side of the dashboard (driver's side), where the dash mates to the door when the door is closed. Check there and see if you can pop off the end panel on the dash.
