BMW e46 318Ci Crankshaft Sensor Installation

HI All,

I have been looking everywhere for a installation guide on changing the CrankShaft Sensor on a 4 Cylinder 318ci e46 2003 Convertible. Could anyone point me the way to a guide on how this is done?

Last question, my previous E46, i could close the windows with using my KeyFob, but this car does not do it? how can i get this feature working?

Cheers friends

Simon

IS the crank at the right hand side of the engine block?

N42 engine? You have to take out the intake manifold. It's item #3 in the pic from bmwfans.com below. It's kind of a pain to replace if you ask me but pretty straight forward. Oh, and you have to remove the cabin filter assembly before you can remove the intake manifold.

Good Luck!

Is the removal of the inlate Manifold a fairly simple task? or is they aload of cables to disconnect etc.

I aint doing it, taking it to the local mechanics just wanting to get an idea of times etc and difficulty.

Thanks for Replying

No problem!

I would say it is a hard task for new DIY'ers while It would only take a seasoned mechanic anywhere from 25 to 40 mins to do this job.

Good luck!

Listen, it's a simple job if you put the car on a romp. It's location behind the starter. I watch my mechanic replace mine last week, and he didn't have to remove anything to get to the sensor. I would say, it's a ten minutes job, only one screw to remove,using an allen key.

It depends on the engine as to where it is located and how difficult it is to get to. My engine - it was a PITA to get to and took me hours to get it done as things had to be removed. Though - I didn't have to take off the manifold like the OP will need to with the N54 engine.

i think its easy with I6 engine model as you said, but for my RHD N42 engine, it wasn't easy to access even car on the ramp hence removing the intake would be the only choice.
