When it rains, electrics give trouble, help!

[tringo007]

Hi, I have a MK7 1.4 TSI DSG. When it rains (and only when it rains) some electrics start behaving strangely. Eg the Front Assist overreacts ie when I am far from the car in front it beeps and the front assist warning appears. Also the reversing camera that came with the car doesn't open. Any idea where the center of these electrics are that water may be getting into that I can check? No fault codes appear in VCDS. Other ideas welcome.

The problem with these cars now is, a single faulty wheel speed sensor (for example) could cause these errors.

There's no logical way for you, as an end user, to know what's faulty or to work this. Only the engineers who built the silly thing have the troubleshooting flowchart for electrics.

Do VW in the UK use Lucas electrics?

The front sensor issues could well be rain related as rain drops can make the sensors act wonky.

Does the camera act up at the same time as the sensors? i.e. during the same type of weather or every time it is wet?
