Hi all
Only had my new M5 for 2 weeks, 1st week was fine, then all of a sudden on cold starts as soon as it fires up i have strange loudish buzzing noise that goes after a few seconds, then off...its been back to dealer who says its normal? never did it 1st week...i know its got lots of gizmos that power up but is after its fired...
Also on cold start it revs straight to 2k...is that normal?
cheers
