Hmmm, if the diameter of the bolt is small...I wonder if the sunroof tool will fit it. It's hard to believe that BMW would have something on the wheel that didn't have a tool in the toolkit to remove it.
Also, the Touring has a small socket and the larger spark plug tool (see the two #7s in the diagram for the Tourings tool kit): Diagram 7 part # index of e34 Touring's toolkit
I wonder if the small socket (in diagram above & pic below) fits...or like I mentioned earlier...the sunroof tool (since it has the shape of an allen wrench)...or even one of the smaller wrenches (spanners) in the trunk's tool kit.
Just curious?![]()
