I'm going to be replacing my starter on my 2006 N52 and have all the parts. I looked at the instructions in the Bently manual and it has the torque spec as 20nm + 180 degrees for both starter bolts. But from a few other places I am seeing that the long bolt is the 20nm + 180 degree, and the short bolt is 20nm + 90 degrees...was this just an update by BMW at some point and the latter is correct? I guess the latter could take into account the additional stretch that happens with the longer bolt vs the shorter to give a more even final torque loading between the two bolts?
