I been trying to attack this problem for a while.

Controller: 4B0 820 043 Q
Component: A6-
Note: Excessive Comm Errors

For the CEL it keeps coming back everytime i erase it after 2-3 trips. I tried a new gas cap but that didnt help. After reading previous posts it might be related to the N80 valve.

I have a VAG-Com and AllData. All Data gives instructions for N80 valve using VAG 1551 or VAG 1552 would the same numbers and measuring block apply for using a VAG Com ?

Can anyone give any other suggestions about these error codes or what else to check and test?

Also can someone point me to where the Canister Purge Solenoid N115 and or what it looks like also where the

Evaporative Emission Control Canister is and what it looks like.

Thanks!
