what now? |
Can you please try the starter? (Malek's theory.) I had a starter fail in my E39 M5 years ago and the sound wasn't far off this E9X issue.
As far as the seriousness of the issue -- common to both of my E90 M3's, and present over almost 50k miles combined. Both engines are flawless post-startup. No engine related problems other than an ignition coil for my 6MT. If this was a sign of a more critical issue, I/we would know by now. I say "we" because at this point we know it must be present on hundreds of M3's (or more), with hundreds of thousands of miles collectively. Other than M3PO we know of no one who has had the issue successfully addressed, so then where are all of the critical engine issues emanating from the noise?
That said, it would be cool if you figured it out conclusively...
Either assign it to the starter, or confirm M3PO's repair.
