ahh, yes....mine also.
i also had this "error message" appear last week, but one time only for the right rear taillamp assembly as stated above. all is working ok for the moment, so should i look into this a little more deeply (on my own) or see the dealer since it is under warranty until 12/31/11, and would the "damage be readily apparent? btw, it's an '08 535xi with 34xxx mileage. thanks...
