2008 X5 3.0 with 50,000 miles
2 months out of BMW warranty with still in extended warranty.
Engine is very loud when I start in the morning and it is cold outside. It becomes quiet after a while. Earlier it used to be once in a while but lately it is become more frequent. On my last service I mentioned it to the mechanic but engine was smooth and quiet by that time.
Based upon the noise the mechanic suggested exhaust leak. any experience / ideas?
I don't mind waiting but don't want to be stranded?
