This may be the crux of the issue.
The BMW dealer that trashed your motor told the inspector "the position of the vanos cannot be ascertained prior to insertion".... they are therefore claiming the vanos was 'bad', they installed it, and it damaged the motor when it 'realigned'.
Had you posted this in your other threads, all the knowledgeable people who had posted in there might have received an update (perhaps an email notice) and could have replied.... In reading on VANOS (and on Phillym5's comments) you can, actually, check the valves and vanos psotions when you set the timing.
Hans doesn't understand how vanos work- nor does your dealer- and the dealer has led Hans down the path they want.
I suspect they are lying about 30 minutes of running. I wonder of there were any DME tests that would show operating hours prior to, and just after, the 'event'.
My 2 cents.
You will now get a rash of people's opinions on their VANOS problems, but might not get the attention of the folks that had weighed in on the other threads...
