Hi All
Changed this sensor on my 2 litre at the weekend. Thought it might be helpful to share the experience as I could find very little info on the web about the 2 litre.
Bought the vdo sensor and gasket kit from Autodoc. The original sensor when extracted was marked BMW/vdo Siemens.
Remove the cam cover as per normal (AccureTech on YouTube is a good guide).
The sensor is held by 3 10mm bolts. Stuff rags in all the possible places the bolts could fall!
The middle one requires a 1/4 drive socket as it is accessed through a hole in the timing chain guide. I found a deep socket that I put a magnetic insert in was just right. The 2 outer bolts can be removed with a ring spanner as long as the wall of the ring is slim. I found Halfords advanced 10mm worked fine. The left bolt looking at the engine is very awkward to remove as there is no room so pliers to grab it helped. The sensor holes on the n46 are not threaded so the bolts can be removed complete before extracting the sensor.
Replacement is a reverse of the above.
Once everything was back together I cleared codes and then put the key in ignition position 2 for 2 mins, turned off for 10 secs, repeated for 2 mins and everything started up ok.
Much smoother and no codes!
Hope this helps someone with the same problem.
