06 650i high pitch sound while holding brake and gear at a stop
Hey guys. Quick question regarding my 06 650i. It has 214 hours on it and recently it started making a high pitch whine when im at a full stop and its in gear. I had assumed that it needed a belt adjustment so I had it brought over to the local ATV repair shop the mechanic said the belt was fine. Now I keep the 4-wheeler about an hour and a half away from where I live on my parents property so I didn't have the opportunity to meet up with the mechanic in person.l, although I did explain to him how he should try to replicate the sound but he said he didn't see anything abnormal.
I'm hoping someone here might have an idea of what might be causing it, because it never used to do that. Thanks in advance.
