Engine is available for inspection upon request. Earlier this month, my 550i completely shut off at a traffic light. When attempting to restart the engine, the Starter strained very hard and smoke came out of the engine. Engine was immediately shut off and the car was towed to a local shop. In turn the shop replaced the Starter the following day and heard knocking from the engine once it turned it over. Upon examination the shop pulled open the oil filter and it was full of metal shrapnel. I feel fortunate the car was not in motion at the time of the failure, given the engine shut off with no warning this could have resulted in a catastrophic accident.
