Hello I have a 2001 X5 BMW.

I am experiencing a whining sound when starting my car up in the morning. It appears to go away after it warms up after 15 mins. I do hear it some times when turning right.

Thanks

You have the 3.0 model? You need an updated belt tensoner. They go for about 100-200$ installed at a dealer.

.first,the whinning sound could be the air pump which is electrically operated which only runs when engine is cold,sits on the right side of engine compartment,,is there a squealing type noise cold also?could be alt belt and tensioner,i advise to bring to dealership and let them start it cold to isolate problem,expericing the noise when it happens is a big help to a technician espcilly on a bmw ,
