Beeping / honking... High pitched
Hello all. I wasn't quite sure how to search or explain this... So here goes.
2008 BMW M5 Black. 87k, engine rebuilt by Troy Jeup. Car runs great.
But I noticed the other day that when I would lock my doors, the recognizable "lock chirp", was a completely different tone. Like a musical key off. I also noticed that my horn was also very, very pathetic sounding. As if my horn was replaced by a dogs chew toy.
A few days later, my horn and chirp resumed back to normal. Then today, the lock chirp and horn went back to the weak sounding tones. The only thing that I noticed was my car battery gave me an error message last week about voltage... I was on vacation for a week so my car sat there. The message went away.
Anyone ever experienced this? Thank you.
