The service manager called me on Saturday afternoon and left a message that the car is done. he said I was right about the carbon build up but they didn't use walnut shells to clean the valves out. He said they used another BMW authorized method? I'll find out when I get it. I need to drive an hour and a half out to the dealership to get it. Hopefully the weather will cooperate at 7am so I can head out there right after work before this "ice storm" hits us. I'll definitely keep everyone posted.
