Buzzing noise from solenoid area in engine
My 2012 X3 35i has recently developed a buzzing noise that seems like it's coming from the left side of the engine (as looking at the engine from the front). I was in for my 30K service the other day and wouldn't you know it wasn't making the noise nor were they able to reproduce it. It seems like it could be outside temp related. It's warmer the last few days and the buzzing is back. Could something be going in the solenoid? Anyone else have this sort of sound?
