It certainly fixed mine a few months back. I used to get abit of a misfire when the engine was cold, especially on cold mornings when abit of damp was about which probably upset the worn tracks of the sensor and used to trigger the EML light at times.

Since ive changed it its been absolutely fine, not 1 problem since and only a 5 min job plus about £65!

I was experiencing the same issues relating to a "misfire" like sensation at a certain throttle position. I changed the throttle position sensor and it has eliminated the problem.

This relates to the S50 I assume, as Craigs car.

There is one on the S54 as well, I've read its well worth changing as a preventative measure given the age of the car. I picked one up from dealers but never got chance to fit it this summer

Fitted a new throttle sensor this weekend as the misfire was getting really bad at times; seems to have cured it now!!

I got it from http://www.bmminiparts.com/ , about £36 delivered. They list two parts, the part number I got was 13631402143 which was the same part number already on the car. See two switches listed for Part 8 here (
http://www.bmminiparts.com/DiagramVi...060&MOSP=48075)

Realoem list the 143 switch as for the M3 CSL only (http://www.realoem.com/bmw/showparts...=11&fg=40&hl=4) which is a bit confusing as my S50 had this part number fitted already. BMMINIParts said one has probably superceeded the other, but from the dates the 143 switch sounds like the older one, but then only fitted to the CSL which is the newest car, the 383 is most likely to be the newer part (it may be more durable, not sure). Either way mine seems fine now!!

S50 part number is

13637840383

Part number 8 on RealOEM here

http://www.realoem.com/bmw/showparts...79&hg=13&fg=15


S54 part number is the same

13637840383

Part number 2 on RealOEM here

http://www.realoem.com/bmw/showparts...11&hg=13&fg=15

If you search on the part number it fits loads of ///M cars from e36/e46/CSL/Z3m's S50 & S54 and even the Z8 so it must be an upgraded part.

Assuming it's the same between models, really simple straight swap

Yes, just swaps over, two little screws hold it on. There was a superceeded part number but both should work fine.
