Help with installing bulbs!
I did a simliar in my old car. I phone up BMW assistance and i explained i was changing bulbs and i dropped a metal pin. they suggested taking it to a local dealer but once i explained that i couldnt as the pin could get lost and in your case you need the car at night (bulbs) they immediately sent out a local technician. He used a magnetic rod to fish out the pin. He was quite happy to do it and said that is what they are there for.
