Perhaps this is a long shot but thought I'd take a run at it anyway... The picture below is of the mechanism that allows the radio cover to stay closed and to open when pushed. As I mentioned in a previous post, mine is missing so the door won't latch in the closed position. BMW says that the white plastic piece is only available as part of the whole assembly ($800!). The plastic piece is held on by the metal spring clip and truthfully, should cost a couple pennies to make. Installing the assembly requires removing the instrument cluster and a whole bunch more plus, my carrier assembly is perfect cosmetically so I really don't want to have to replace it. In thinking about this further, I should be able to simply insert a new plastic piece onto my existing carrier while it is installed in the car by removing the radio and just reaching in with my hand or some long pointed pliers. So that got me wondering if anyone has one of these pieces or knows a way for me to source one. Maybe 3D printing? This looks like a part that BMW could have used on numerous models from that era?
