HELP! Car wash & now all kinda of Headlight malfunctions

Milestune · 03-17-2019, 01:14 PM

Hi. 2011 550XI. Went through the car wash (as usual) and when I came out, I got the following errors:

Adaptive Headlights Malfunction, Left turn signal malfunction, Daytime running / Parking Lamp, Headlamp Vertical Aim control malfunction.

The right turn signal had a malfunction at first, but it went away.

The Halo's and XENON lights work. I have a side marker light that's out (but I don't think that would cause an issue) Left rear turn signal works.

When I shut off the car, the left front halo and corner marker both stay on, while eat right does not.

I checked all the fuses.

Obviously water got in somewhere and messed things up. I had that happen on my MB where water got in through a failed tail light seal and fried a board, and everything went to shit

Yes, it was water getting in via the rear headlight cover... I pulled it out, dried it up real good. Let the car sit for a few days... VOILA! Fixed itself!

This happened to me yesterday as I took the car to car wash. I was about to take to the dealer this morning when all the messages disappeared.
I looked at the headlight and I can see a small amount of condensation on the inside of the headlight.
Ill still take it to the dealer to see if they can do anything to fix the seal.

Well a car NEVER fixes itself, it is just working for now.
Also now that it has been wet you can expect it back sooner vs later.
The vertical aim is the side to side movement.
For that I would say the motorized unit, but the other parts staying on
would point me to the module.
