I got the same message while parking but no noise or anything, so I guess the message can apply to several things. In my case the internal code says is the generator sensor (I ordered a new one in ebay and the code has not come back).
Do you checked what error code you got? with something like Car Scanner app and ELM327 bluetooth dongle
