2008 Alhambra 2.0TDI, VAG-COM 14
Have had some problems with this car, having bought it about a year ago.
I've changed the radio from a dual unit CD/Radio to a single one (I needed the dash slot for other equipment) and co-incidentally (or not) my regular VAG-COM scan showed up the 01336 Data Bus Failure error. A number of modules are no longer accessible...
Clearly this is something to do with the CANBUS and possibly by fiddling around with the radio unit, I've broken some wiring. Possibly the CANBUS adaptor I got from Germany may have caused some problems but removing it temporarily didn't restore the CANBUS functionality.
So, apologies for the intro - what I can't find is where the CCM unit actually is, or what it looks like. It would help to know where the CANBUS wiring actually goes to. Perversely, despite the CANBUS showing as a failure, the car is running quite happily and where the units are contactable by VAG-COM, they are showing no faults. Except for the CCM !
Any help, thoughts, guidance much appreciated. I have an electronics background so feel that I should be able to crack this problem.... once I find the critter !
