    Have you had it scanned for fault codes?

    I would suspect maybe the alarm siren batteries have leaked and fried the PCB, or the comfort and convenience module under the front passenger seat has got wet. Check the carpet to make sure it's dry there, are the drain holes under the battery free?

    Or it could be a multitude of fault microswitches?

    I'd go with door locks, or ccm mate.

    I have VAG-COM if you want a scan doing to see what comes up to get a better idea? It would be better than going in blind so to speak, as that can soon lead to wasted money.

    Check the wires that go from door to car for breaks, pull back the black rubber boot and check

    I would go with broken wires inside where the doors hinge or bad connections in the plugs that are in the same area... they can cause lots of different problems... intermittent speaker's, central locking, door light's, puddle lights, interior lights... all go trough this ... I've done repairs on 3 B6's all with broken wires inside the rubber gaiter at the hinges

    We might be able to help more if you posted the FULL VCDS scan results.

    Agreed, plug all those codes into the wiki and see what they diagnose. Here are three straight away that will point towards your issues, broken wires in the door hinge are a good place to start by the looks of it.

    Have you checked to see if the carpet is wet yet?

    For example: 1333 -

    1331:

    There's alot of padding under that carpet. I'd get it lifted and properly check for water.

    I would check inside those rubber gaiters at the door hinges first before I started ripping up carpets... honestly it's a really common problem for the wires to break

    Agreed, and from the fault codes I've referenced for you it's the most likely issue.
