The amplifier for the M Individual Audio System overheats and turns off. The affected amplifiers are not equipped with a cooling fan. (Vehicles produced up to March 2008)


Install an improved amplifier (including a cooling fan) for the M Individual Audio System.

Thanks for posting this information. Did the technician that posted this TSB information on Bimmerfest provide the TSB number? I have an appointment at the dealer tomorrow for them to drain the oil and check that either enough or too much is in afer their break-in service last week. If I have the TSB number to point them to, I can see if my car is affected and needs the fix.

Thanks again for this valuable information.
