How does iDrive being VIN locked become, "I can't work on my engine"? Also definitely want a source on the N52 requiring iDrive to start, because obviously not all the cars with the N52 even had iDrive... It sounds like you're oversimplifying it. iDrive probably fails in a specific way that causes a problem for the car's network, not BMW intentionally had the car stop working because your music couldn't play. That would be exactly in line with what I said about complexity being the issue, not some concerted effort to get you into the dealership. It's confusing a bad design with malice.
