Mobile phone charging triggers waning

Dear all, my 2017 330i recently has some weird things happened to her ... when I charge my mobile phone I got warning saying the “front high beam light malfunction” and “SOS calls disabled”. When I parked the car and shut the power down, I heard thumping noise like heartbeat, the noise went away after a few minutes. The next morning when I started the car all is normal, but when I starting plug my mobile phone charge via USB port, the same warning signals come back in a few minutes. It is so weird and wonder why? I took the car to a local BMW repair shop, they could not find anything wrong with the electrical system. Does anyone here experience similar thing? Otherwise the car runs great . I only put 32K on it. Thanks a lot. George

sounds like you may have some wires crossed. Is your car still under warranty? If so, take it into the dealer and let them sort it out.
