My Allroad (2001) has just started giving a weird set of symptoms: When driving, the interior lights fade up and down, accompanied by sounds of the door locks activating. As none of the footwell lights come on, I don't think it's a door switch. When I unlock the car, after a few seconds the windows all open. This is not because I'm still pressing the button. This is intermittent. Sometimes they open fully. Sometimes they move down a few millimetres at a time, at about one second intervals. Sometimes there is no problem. Pressing the lock switch on the driver's door locks the doors. Often, but not always, the driver's dor then unlocks again. After the windows have opened, sometimes holding the lock button on the key will close them, sometimes it doesn't. The door locks make noises occasionally too. When the car is locked, it behaves itself. I suspect the wiring loom between the drivers door and the dashboard area. Partly I suspect this because I have had problems with it on previous Audis, partly because broken and shorting wires on the door controls could be the cause. However, I've taken the door panel off and checked the loom, which looks OK. There was an increased amount of activity from the windows and central locking while I did this, but I couldn't tie it down to movement of the loom. I took the lower dashboard panel off. Again moving the looms about might have increased the activity. Has anyone else seen anything like this? Is it likely to show up on the diagnostics? What do you suggest I try next?
