A4 B6 2000 intermittent fault

[Grover2000]

Hi could anyone advise regarding a fault with my A4.

The alarm has been going off, the rear doors remain shut (despite trying to open them from the inside and out), Interior lights are on and off and central locking has a mind of its own. These are just some of the faults which are all intermittent.

I have done some reading up and it seems that the blame points to Central Convenience Unit. So I stripped the interior passenger area to expose the module and to my shock it seems to be dry as the Sahara. The surround wires are also dry, I also inspected the module for dry-joints and found it to be spot-on.

Can anyone one advise where the fault may lie?

Any help on the matter is greatly apprecited.
