Two problems related to exterior lighting have been reported for the 2009 BMW 3 Series. The most recently reported issues are listed below.
Upon returning to seattle, wa, since I flew down to berkley, CA to purchase my vehicle, I noticed excessive headlamp shake when going over any bumps on the highway, especially expansion joints. Both left and right headlamps shake equally as bad, and I consider that a safety hazard while driving. It is very distracting and searching many online forums, people have been having many issues with the adaptive headlamp bracket arms being broken. Cpo warranty does not cover headlamps according to BMW, and they are not willing to pay for both replacements.
2009 BMW 328i, the directional light at times blinks rapidly and a warning of light problem illuminates. The directional blinks fast and light is dull on exterior tail and front lamps. At times works normally and then begins to blink rapidly with a bell warning and electrical warning light sign displays. This problem has known to BMW as the service dealers received a bulletin. Will not cover if out of warranty but seems to be a common issue enumerated by many customers.
