Hello all,

Yesterday I had the EML come on and after being scanned it is showing the following codes:
P0335
P2090
P1381
P1378

P0335 looks to be the crankshaft position sensor ‘A’ circuit.

I have a new sensor on order but struggling to find any diagrams or videos on location of said sensor.

Can anyone help guide me to where this is?

Thank you,
Will

For M57 diesel - Hidden down by the dipstick, single Allen screw holds it in. There should be wiring to it that you just need to pull off.

My apologies I forgot to mention it’s the 4.8iS! I’ve seen some contrasting information on the location, either access it from the engine bay and strip some parts down, or access from underneath and it can be a 15 minute job.

Thanks,

Two possible locations is all I can find….
No instruction on changing them at all in the data I can access.

Great, thank you again, at least it narrows it down to two possible specific places!

I’ll take a look over the weekend and hopefully find it…

Cheers,

Thought I’d post an update on the off chance someone else with the N62 needs to replace this part in the future.

Thanks @X5Sport for the guidance, to clarify the sensor is located on the transmission bell housing. I found the best way to access the sensor is to jack the car up, put it on stands, remove the drivers side front wheel and you should be able to see the sensor above the anti roll bar. I have included some (hopefully) useful images to show exact location.

The sensor has a metal retaining clip on the plastic plug, remove this, unplug the plug, then remove the 5mm Allen bolt holding the sensor in place. It should then just come out. Very simple once I found it! It is a bit fiddly with only a small space to get your hand into, but overall a very simple job.

For context, I called my local BMW indi who quoted approx £250 for the part and fitting. The sensors can be found for as little as £13 on eBay but I went for a febi part which was £30.

Thanks,
Will

Glad to have been able to point you in the right direction. BMW parts prices are silly (and getting sillier!). I needed 2 pressure sensors for the ABS/DSC on the E46 and they were over £100 each. Sadly no other option as it’s a rare part. Had them fitted by an Indy though….which brought the total cost down, but!
