Hello there,

I got an Audi A6 C6 from 2007 with battery drain issue.
I was checking the values in Can Gateway for Can Status and saw that WakeUp line remain active and Comfort and Infotainment remain on, and they don't go to static.
I'm attaching here the full scan of the car.

Can somebody help me with some ideeas?

Of course comfort and infotainment will be on when the wake bus is active. Wake-up activation occurs when the driver door is opened or unlock command is sent from remote button/key. Has this car got KESSY? has there been any recent work on the door latch or so? whats the current close-circuit current after locking the car for 2 hours?

Hello there,

I got an Audi A6 C6 from 2007 with battery drain issue.
I was checking the values in Can Gateway for Can Status and saw that WakeUp line remain active and Comfort and Infotainment remain on, and they don't go to static.
I'm attaching here the full scan of the car.

Can somebody help me with some ideeas?

OP did you do a voltage drop test at battery with alarm armed and zones bypassed yet verifying each zone?

Did you observe this yet \/ ?

The car doesn't have Kessy.
I bypassed until now the back door where i see errors by removing the from can gateway scan, but it was the same issue.

I just check by removing the fiber optic from can gateway module and observed that everything is going to sleep.
Then i started bypass the modules closing the fiber optic loop with a bypass cable:
- DVD module: issue still there
- Radio Module: issue still there
- Digital Amplifier: issue still there
- Media Player: issue still there

Unfortunately i can not bypass the Telephone module because even using the bypass all the devices goes to can not reach state.
Same issue it's happening when i'm bypassing the fiber optic from can gateway module.

With this results it means that 77- Telephone module has an issue or 19-Can Gateway has an issue.
I will replace tomorrow both of them and come up with the update. For sure after the change i have to remove CP.

Not saying this is your issue, but it may give you some ideas of looking for micro voltage drops across fuses, and putting a switch in-line of a suspect circuit to isolate.

I had a intermittent battery drain that was maddening to troubleshoot. I documented here and the text is below. https://www.golfmk7.com/forums/index.php?threads/infotainment-unit-draining-battery.379517/

Documenting this in case anyone has a mysterious intermittent dead battery and are unable to find cause. My battery would be completely drained and it was an intermittent problem. Battery would go days without a problem and then suddenly dead overnight. After ruling out the obvious of a bad battery, performed all the normal failure analysis for trickle drain (looking for micro voltage across fuses) etc. which was unsuccessful. After many months of disconnecting battery at night, I was doing something in my car and the infotainment unit turned on by itself. I then put a switch in-line with infotainment fuse for a few weeks (turning switch off when car was not in use) which verified the problem was the head unit (battery never lost charge). Replaced head unit, removed CP (component protection) reinstalled Functional enablement codes (FeC’s) associated with VIN and problem solved. The problem unit was an early MIB2 3Q0035844 which I swapped with a 3Q0035844B.

It may not have full "keyless" functions, but definitely has a KESSY module. ;)

-Uwe-
yes , it doesn't have keyless entry but KESSY module for start Auth it has.
