Either way, I'm becoming slightly worried about the whole process and getting a working upgrade.

Update: The dealer was sent the wrong combox for my X1. It is going to go through a final road test this morning and should be available this afternoon. I've had a 528i that I'm happy to give back. Anemic engine for that big car.
