Audi A6 several weird electrical faults

[V Mad]

For no apparent reason my driver display shows the doors are open when they are all shut (I checked them all). The windows will not operate, nor will the interior light. All these faults happened at the same time, so I think they are all related somehow. I guess that one of the door sensors has gone faulty, but where are they and how do they work? One other thing, sometimes the hazard flasher start up as well after the car has been locked and parked up for a few minutes.

I feel claustrophobic not being able to open the windows. Cam someone help please?

I'd put money on it that your convenience ecu (located under the front passenger carpet) is full of water. This will need replacing but first you need to locate where its coming from. First check your rear washer is working. If not can you hear it coming into the footwell when operated? if so you need to reconnect the pipe in the footwell. If it works ok then check the plenum chamber isnt blocked. And finally if thats ok check the pollen filter housing seals correctly.

+1 for a sub-aqua convi ECU.

I had a plenum blockage in the winter, got the carpets all wet. So that will be the problem guys, thanks for the heads up
