The crank pulley bolt and washer for the M47 is a euro market only. Stock is a M18x1.5x102 bolt. A readily available alternative is the N20 crank pulley bolt which is M18x1.5x108mm. The parts list do not list any dimensions of any of the washers.  For the Australian market at least, the E90 320D M47N2 washer is a possible option. Part numbers highlighted below in red.

The bolt and washer is with the engine builder and if there are any issues with them, I update. Part numbers and specs are:
