Just finished up my engine rebuild on my 2007 mini s r56 I have the engine back in the car but since I bought this car with the engine already tore down and the parts in four boxes
its been tuff, my last problem is a sensor at the bottom of the fly wheel its square and has one bolt to hold it in, I can see clips for the wire on a plastic insert at the fly wheel but have no ideas where the sensor goes. Please help...

 

Maybe crankshaft sensof?

The pic on the link you sent me looks just like it, hopefuly I can install it through the inspection cover, if not what a nightmare.
