I have a friend who went in with a M3CS transmission flash on his DCT M3 and it was auto flagged and now he's got no warranty on the tranny. Had nothing to do with the dealership, it was auto flagged by bmwag.

Also dinan is factory warrantied (or at least has a matching factory warranty) so in your case it really wouldn't matter. If you had any other brand of tune or flash the outcome of that may have been very different.
No that's not how it works. It might be discovered but if your tech and SA doesn't put it in the file it's not flagged.
