My 10 year old passat first showed signs of problems when the interior lights stopped working. This has now been followed by the power windows, wing mirrors, central locking and finally the car alarm kept going off. I fixed the alarm by removing the fuse for the CCM. I did note a build up of water in the bulkhead below the battery but have since removed the battery and checked the drainage which seems clear. There are no other signs of problems.
Please could anybody advise what could have caused the electrics to fail and secondly where is the CCM located and is it a straght forward replacement for a new part?
