Is there a list of DTC Codes available on the internet?
I have looked through the list that Bentley has on their site but I'm unable to find some of the codes.
Someone pulled the codes from a '97 A8 I'm interested in buying and here's a list of them:
Engine Controller Codes:
18010-P1602
18020-P1612
16705-P0321

Instrument Cluster Codes:
00771

Central Locking Codes:
01367, 01371, 01372, 01374, 01370, 01369, 01368, 01373

If anyone can point me in the right dirrection it would be much appreciated.

Thank you

If you do ever get an audi purchase the Bentley repair manual. It will list the codes you posted.

00771 - fuel gauge sensor (G169)
I had this code too. It said to replace sensor. The symptom for my 97 A8 was the fuel gauge in the instrument cluster would at time not full register. Now when I fuel up I shut the engine off but energize the system, meaning I turn on the car with the key while pumping gas. Have never had the problem again.

18010 - low voltage power supply on B terminal
18020 - Electronic Control Module
Incorrect code
Replace ECM.
16705 - Ign/Dis engine speed
range/performance
check engine speed sensor.

That's about all I can help with for now.
