If all else fails you may need to change the central lock system control module. You need to supply dealer with Vin #

SOURCE: my hazard warning switch light has remained on

Either 1 of 2 things. Relay inside hazard switch goes bad often. If that is not it, then usually you would end up replacing the actual turnsignal column switch. But a new Hazard switch should do it.

You really need a dealer to reset the anti theft and key recognition.There are very few independent shop who can successfully do this .

It does sound like you also might have drivers door micro switch fault...very common as the vehicle gets older . Have the shop can for faults in the body module. It will store a code if the door micro switch is not working.

If you like reading about VAG vehicles and seeing how to fix problems, try a visit to where you will find the VAG community sharing the fixes and problems on these machines.

A6 turbocharged. Whyu does it smoke when it covers a 120km per hour?

I am going to say 'blown turbo'. As I understand it, they needs replacing every few years. They are susceptible to heat and incredible revolutions. They have to be lubricated, the seals go, and you get smoke.

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?

The battery on my 2003 Audi A6 keeps dying. I

Sound's like a bad alternator, you can check the alternator by measuring the voltage on the battery when the car is started, it should measure above 12.6 volt's but not higher than 14.5 volt's, check the drive belt tension, a lose or wore drive-belt could cause problem's with the alternator charging the batery, check the battery terminal's for corrosion, along with the connection's of the battery cable's.
Hope this help's, good luck.

Rust on an Audi TT

Audi give a 10 year anti corrosion warranty.
Take to dealer and get them to look at it. I took a 7 year old A4 down and they repainted the bootlid under warranty.
