I have similar issue to this... Q3 1.5 MHEV (48V with BAS), noise is coming only when engine is started, indicator right is on (bzzz......bzzzz.....bzzzz) or during the normal drive, when you release the gas pedal (energy is going to 48V acu) or when break pedal is pushed (also energy is going to 48V acu).
Car was already checked by dealer, SOS module was exchanged (but NO LUCK, nothing changed).
I have second Q3 1.5 at home but with MHEV 12V, and this problem is not appearing.
Any idea what can be a problem, mayby lack of some filter on 48V instalation, or badly inverter module, BAS???
Please help
