Yes, I saw the G20 thread re Harman Kardon (which I also have but seems to be working o.k.).
“With the two special equipment (optional extra):
SA 6U3 BMW LIVE COCKPIT PROFESSIONAL
AND
S-0688 HARMAN / KARDON SURROUND SOUND SYSTEM
A diagnosis must be carried out in the event of a customer complaint.
If the fault memory entry in control unit RAM01:
B7F480 - Booster no connection is present and no other cause can be found: (For example loudspeaker noises or background noises originating from the end device ), the control device is:
Replace amplifier Top-Hifi-System with the following part number:
65 12 5 A38 AB8 amplifier top hi-fi system”
Given there was a bulletin re HK, are you getting the faulty amp changed also?
