BMW hasn't allowed dealers to crack open their engines for quite some time. Thus, every engine warranty claim is reviewed upstairs.

This is the reason why I have been reluctant to tune my car. It's the "what if", and do I want to be SOL.
This is exactly what had happened to some folks with the E60 M5s with bad SMGs with Tuned ECUs. The claim gets pushed up to BMW NA and they will go through the protocol and check the ECU. The dealer won't even touch it until it gets approval from BMW NA.
