Hello Leute,
Bitte mein Englisch entschuldigen.... 
I hope someone can help me with troubleshooting this problem...
Earlier this year, I bought a 2013 BMW F10 (pre-LCI) with xenon adaptive headlights. Since then, I've taken it to the autowash at Aral once a month.
The first couple of times I used the autowash, there was no problem. But last month I took it again to the autowash, and when I started the engine afterwards, I got four separate error messages on the instrument panel - one after the other:
- Adaptive Headlights failure
- Turn indicator front right failure
- Side/daytime lights fault
- Headlight vertical aim control failure
Additionally, when I used the right-hand indicator (blinker), it made the indicating noise twice as fast as normal. But the left-hand indicator worked correctly.
These four error messages repeated every time I started or stopped the engine, for the remainer of that day. But the next day they were gone, and the right-hand indicator was working correctly again too. So I didn't do anything further, because I assumed it was just a temporary glitch.
However, this week I took it back to the autowash and the exact same thing happened: afterwards I got the same four errors on my instrument panel, and the right-hand indicator blinked twice as fast, and the following day the errors were gone.
Now I'm worried that perhaps there is a leak somewhere in the car, and water from the autowash is somehow getting into an area where it should not be, and causing this problem. And I'm worried that it could cause more serious or more permanent damage if I don't fix it.
However, I have no idea which part of the car is responsible for these errors, and where I should look to try and find a leak.
Does anyone have any suggestions?
