BMW Removing Intake Manifold, Replacing Crankshaft Sensor E90, E91, E92, E93 

Also a great video for reaching the starter (requires new starter bolts).
WHEN REINSTALLING the manifold, guide the crankcase vent hose underneath the fuel line, and when everything's back together delete the fault memory.
*N52 ENGINES WITH 3.0 liters have a different design for the Crankcase Vent System - you'll need to spend more time unplugging a couple more wires, unclipping the alternator cable next to the firewall and removing the drainback tube off the bottom of the CCV valve WHILE you're underneath there removing the manifold. A friend's help is a good idea.
