Helmsman wrote Irritating. Had condensarion in my right head light after wash as far as I remember since I bought the car 12 years ago. I open the hatch mentionen and let it dry over night. Fortunately never had anny issues with tge functionality though.
I've never had this happen since I purchased the car (second owner) back in early 2023.
Although when I popped the hood, it did look like there was some wear and tear on the rubber seal. However, I just serviced the car yesterday and the tech said the rubber seal wasn't the problem, there were no issues with the elctronics, so they didn't want to do more work than needed, said to keep an eye on it, but if I got an error code that it might be best to go to an indepdent shop to take a look, since it would be $2k+ going through BMW which even the SA said wouldn't be worth it just for preventative maintenance since everything else seemed to check out fine...
I'll just have to be very careful in the rain and when getting the car washed!
