Two problems related to turn signal have been reported for the 2007 BMW 328. The most recently reported issues are listed below.
Both front headlamp assembly's have had to be replace three times due to the bulbs melting their bases - this includes melting of both turn signals bulbs. The cost to replace a single front headlamp assembly is $990, $1,980 for both, times three times. . . . This is unbelievable and is a big problem with BMW 3 series cars.
Passenger turn signal bulb was thought to be out. Brought to local BMW dealer and had them tell me I need a whole headlight since the turn signal burned inside.
