My friend has a 545i and his auto gearshift knob is black leather with like a silverish/matt chrome insert. I believe I have found the part number on realoem but am just curious if gearshift knobs are interchangeable between different series? Anyone have any thoughts on this? Also, does anyone else want to take a stab at finding the part number, this is what I came up with 25167522365.
