I was telling my self that it had been a long time sence I had an issue with my 2000 A6, 2.8. I forgot to knock on the woodgrain dash. I now have NO Headlights, turn signals, A/C Blower, Horn or Wipers!! Please HELP! I have the Ross-Tech ODB-II tool for testing. I have attached the log on the test. Other posts said the issue was caused by the alternator. The voltage gauge is reading fine at around 14V. I don't believe this is the cause. Another post suggested that the Ignition switch could be going bad. If any one has knowledge on this topic please let me know. Thanks !!!

 

i think it would be worth playing with the ignition switch as a starting point, try moving the key back slightly after starting the engine, or wiggling the key around!

 

After I saw the other posts about the ignition switch that was the first thing I did. Is is there any other tests that can be run on the scan tool for better testing?

 

check your fuses

 

I checked the fuses and none of them are blown.

 

Do you by any chance have a solar sunroof? Does the a/c control head turn on but the blower doesn't run as one of your complaints?

 

Yes, This is exactly what happends.

If it has the solar sunroof what commonly happens is the "relay" has an internal failure and makes all kinds of systems go crazy. I was getting my *** kicked by an A6 with the same problem and i spent all day on it while my team leader was laughing at me cause he knew what it was F****r!!!! The part number is 4B0 959 5B9. Ive replaced about 15 of them, matter of fact thats how i got the part number i have a few in my tool box.The parts department will call it a "control module" but its a 6 pinrelay, it costs over $100 though.

 

Do you know where I could find this in the car? Suggestions on where to purchase?
