Electrical Problem
Hey all, I have a strang problem... Over the summer; every now and again i would here a couple of beeps comming from the trunk area but never gave it much thought. Once the weather would get cold, the alarm would go crazy while the car was running! Now nothing works! Windows, sun roof, electric trunk, gas door... I think the central locking module took a cr*p...
Any ideas???

Yeah, the beeps where the alarm horn in the trunk, it's internal battery....
is aged and isn't maintaining full cell voltage, thus the warning beeps.
The other issues have to do with the Central Convenience Control Module, have the CC CM scanned for fault codes.
The official fix for the horn backup battery, is replacement of the alarm horn.
There is a write up on the TT forums, describing opening the housing and fitting a new battery instead.

Re: Yeah, the beeps where the alarm horn in the trunk, it's internal battery....
I have no codes, all fuses are good. So the correct discription is Central Convenience Control Module not central locking control module? or are these two different things! Is that the direction I should be going in? Can i scan that with a modis or do i need a Vag Com? Thanks for all the feed back... Much appreciated. this is driving me coocoo!

Re: Confirmed
Plugged it up to Vag Com; Have no cumunication with CcCD ! I unplugged it and put it back; it worked briefly and then stopped again. I guess i will have to price at dealer in the morning. Thanks fo all the input..

To scan the CCCM, VAG-COM/VCDS is required. Generic code scanners can't ...
access the controllers other than the engine ECU.
As you found out, if the VAG-COM scan can't establish solid comms with the Convenience Control Module, then the control module is defective.
The Central Convenience Control Module controls all of the locking and security alarm functions, as well as manages the remote locking transmitter/receiver functions.
The B6 does not have a Central Locking Control Module. The functions of the CLCM are incorporated in the CCCM.
One of the most common causes for failure of the CCCM is water leaking into the driver's side and running under the carpet where the compartment with the CCCM is located just forward of the driver's seat under the carpet. Make sure there is no water under the carpet.
A used module can be purchased a for much less money compared to a new part.
