I have a 3.0 tdi sline 2008 which has been faultless for 3 years. Within the past couple of weeks I have been getting multiple warnings, some with symptoms and some without. I am hoping it is all linked to one problem, if not I am very unlucky and about to be very poor.

- Advanced Key door proximity intermittent not working for a couple of weeks and now not working at all.
- Xenons, headlight range detection fault warning, again intermittent but now permanent. headlights do not adjust when coming on, lights seem to move and wander when driving at night and point low in the road.
- Park assist not working for a morning, no screen and flashing dash switch
- Tyre pressure fault warning, happened twice, tyres fine
- Suspension fault warning, happened just once today, car handles fine

I dont know if these all run off the same control module. Could there be a common ground short somewhere? ( I can hope ). Could a battery on the way out cause voltage issues?

My garage diagnosed and said that both headlight sensor/motors were faulty and needed replacing, same for door sensor. Good garage so need to question them otherwise but seems strange that these other warnings are now appearing. Error codes did note a ground issue on a parking sensor.

Anyone with similar problems?

The microprocessors are sensitive to brown-outs. When multiple electrical problem present at the same time, I would look at the battery. If the battery and charging system are good and solid, then pinpoint looks at the faults is the next step.
