First thing I would do is bypass the battery management module. If things did not come to life, I would apply +12 v to the module connected to the OBD port. Things will likely come to life. Troubleshooting continues to find a broken wire/connection or faulty module.

Mister Bally,
That is great information. I will not have the car back for a week and will print all this info grab my bentleys and go from there.
Is there a good online source for module location besides bentleys cd? I remember a site that had great information, just cannot recall the exact name.
Thanks

no crank
RE: 2004 a8L 175K
Parked car in garage and next day it would only fire for 2sec., this occurred 3 times then no crank and dash was dark. No lights at all. On key turn the MMI and other systems do not act the same and air compressor ran on acc.
Towed to local shop with ross tech and he could not access anything.
Towed to dealer 200 miles away and they said that their equipment could not access ANY modules or diagnostics at all. They want to spend at least a day on itto try to figure out what is what.
Not sure if anyone has had this problem of no start, dark dash (no lights), no crank, and no diagnostic access to control modules.
It is still at the dealer in Colorado with a HOLD ao any work until I figure out what is what.
Any questions or suggestions would be great. Dealer is stumped and mechanic is actually a friend.
Thanks,
