So I went down to the dealership this afternoon to discuss my options for the bike. It appears there might have been a teeny mis-communication before. Assumptions were made that were premature concerning diagnosis of the problem. In discussing the crack with my service manager today it came to light that the FSE had not yet been made aware that there was an issue. My service manager had not seen or heard of such a crack happening before and therefore simply made the assumption that the crack must have been my fault. He left it at that, came up with a repair estimate for me, and did not inform anyone else higher up in the system that he had a bike with a broken case sitting in the shop. After I informed him that such a crack had in fact been seen before and that in that particular case it had been determined that the damage was related to a casting issue he immediately filed a PuMA and sent the information up to the BMW mother-ship. No harm no foul. I'm just glad that we are back on the right track and are taking the correct next steps regardless of what the FSE determines down the road. Obviously this means that no official determination concerning the origin of the crack or whether BMW is going to fix it in part or full under warranty has yet been made.
