Chirp noise when throttle position changes?
I've had my x3m for 2 weeks. It's a 2020 with low miles. Drives great. It was finally cool enough outside to drive with windows down last night. I noticed a very subtle chirp (like a faint smoke detector battery low sound) coming from outside the car when I touch the throttle. I can't replicate it when the car is stationary.
Any ideas? I can't hear it when the windows are up. |

Could be this. A common problem for M vehicles including X3 M. |
