Memoscan Problem
Hey AudiWorld,
I have had a 1999 A4 2.8 V6 sitting in my garage for a couple years now. I finally decided to break down and fix what was wrong with it. A few years ago, I let the car sit idle for about 6 months, during that time the battery went dead. I replaced the battery with a new one, and when I went to restart the car, the throttle valve wouldn't re adapt. So now I can't get the car to run or idle by itself. I can get it to run by pushing on the throttle continuously, but when I let it go, it stalls out.
Alright, now down to my question. I recently bought a VAG tool,(Memoscan U600 VAG + CAN OBDII Scanner) because I heard that the throttle control valve may just need to have some fault codes cleared to get it to re adapt. But when I plug in the Memoscan to the car and try to access fault codes, I get the error "Failed to Connect". Does anyone know why I might get this message? I have tried it on my Acura and had success, but with the Audi it won't connect.
Thanks for your responses!

3 common culprits:
1. Aftermarket radio and incorrectly wired harness.
2. ABS module
3. Cluster.

In regards to the ABS module and cluster, how would you go about checking these systems?
Thanks
