550i 2011 Weird Sound on cold start up?
Hey Guys
New to the forum, just picked up a 2011 550i, Msport, Dinan Stage3 with 20k miles. I have had it for a month and at start up in the Morning after not driving for a few days it starts and while you hear it turning over and starting there is a metal grinding sound. I brought it in to the dealer but they probably did not hear it?
Any ideas?
