Wow op. Been there. Looks like those headlight washers are doing a poor job at keeping the lenses clean.
My 3 series stays in my garage during the winter.
Some of you may think it's crazy but to me, I've been there and done that with a nice car. Salt rust the rotors, gets all up in the engine bay and under body. I rather preserve and protect my investment. I'm fortunate enough to be able to have a second car to drive.
