FYI...I'm driving an 2002 E46 (thinking about buying an X3 too)....but I recently installed LEDs in my license plate, no errors. I'm thinking about doing the reverse and have been assured that no errors will show (none showed with the license plate LEDs). Maybe b/c mine's and E46, but I think if you buy from like Umnitza or JLEVI, should be no error.
