I've scanned through this thread and I'm amazed that your engine suffered such a failure. This is exceedingly rare I think. I agree that following up with BMW NA could prove a wise choice; perhaps they could offer some form of cost-sharing arrangement or similar plan to help out and reduce your expenses. You may have to exercise some patience to find the right person I expect.

And like others have said, all these issues will get worked out and the day will come when you will once more be heading home from work behind the wheel of your treasured machine.

Cheers!
