Here's a good one.
Yesterday evening I noticed that my alarm didn't bip on arming with the remote. After further investigation, I saw that closing the driver door didn't turn out the interior lights.
At this point in time I have no:
1. No power windows
2. No door mirror power control,
3. No heated mirror on the driver side (no heater element in the mirror on the passenger one).
4. No puddle light/red light on the door outside.
5. No power to the central locking actuation on the door lock.
6. No sensing of the lock position.
7. No illumination of the door switches.
The only warning that I got that something was up was the previous day I saw that the one-touch open wasn't active, so I reset that (full open, full close, attempt close when closed, one touch worked again).
The speakers in the door are okay, they make sound fine.
The auto-lock on driving attempts to lock the doors when driving off, and also attempts to lock when slowing down.
Is there an earth cable that might be loose somewhere? Where do I start looking to fix this? I'm trying to see where I should start looking for the issues. I'll be putting the vag-com on this evening, but I've a feeling that'll just confirm no contact to the switches etc.
At least I can lock the driver's door manually, but the alarm isn't arming as it can't see the door lock state.
