Specs for bolts to install E-Wastegate onto N55 turbo?
Anyone with an N55 EWG, do you have the specs for the four bolts that attach the electronic wastegate to the turbo? I was told that BMW only sells the bolts with the wastegate. I’m hoping that someone has the bolt specs, photos, part number? It’s probably an M4 or M6 with an integral washer. Someone told me that it’s an M4x12. I’m hoping to obtain a photo and BMW part number. BMW must use the same bolt somewhere else. Thanks!

It is indeed M4x12 and the official torque spec is 2nm +/- 0.3nm (source: ISTA). Not sure if they sell those bolts seperately but I'm sure they'd be easy to find. Hope this helps!
