First post so hi fellow bm owners.
I know it's probably been done to death but I have a rear PDC problem and I am after some info please.
Mine are completely dead I get no failure tone when engaging reverse,I have tried a new sounder and control unit but still the same.
Plugged diag in and no fault codes logged in memory.
Strange thing is if I am reversing and stall it when starting back up I get the failure tone but that is the only time I ever get any sort of life out of them.
Does anyone know of any common faults than can cause this or have a wiring diagram so I can check feeds etc?
Should also add fuse 24 for parking aid is fine.
