Re: HELP, MISFIRING: 1999 Audi A6 Quattro Avant Wagon
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

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.
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

the serial number off the radio and proof of ownership of the car it
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 solved this on my A6 quattro check the level in your expansion tank (left side of engine bay) if level is low then top up with long life dual anti-freeze/coolant,saves any probs if we have a harsh winter, if full pump on the radiator feed to help relieve poss blockages and make sure water is flowing through the system
You may have a coil pack going bad. They're on the front top of the engine - you'll see them if you follow the spark plug wires back. Do you have any codes from having the engine scanned? If you can get it scanned (AutoZone will do it free), post the codes up and we'll see which cylinder(s) are misfiring. From there, you can swap coilpacks around and see whether the misfires follow the packs or stay in the original cylinders. If they move, you have a bad coil pack or two. If they don't, since you've already changed plugs and wires, I'd see about having the injectors diagnosed to see if any of them are failing.
