PS i have just replaced my Auxillarry Fans and decided to check for the location of my CPS sensor and I could not see it??

I know most of u guys have V6 and all DIY are for M112 engines but is there one for M104?

I understand that it is in the same approximately location as the M112 but some tips on those who know for sure where it resides would be greatly appreciate!!:D

Return the Beck Arnley CPS before you use it, if you can, and get genuine Bosch.. non-Bosch have short lifes really..

My other concern - bad CPS causes either hard hot-starting, or can cause warm engine "cut-off" .. meaning the engine cuts out like a switch has been flipped..

If you have idle problem, or feels like engine is "choking" then there are other issues/things to check.

Keep the beat !

The CPS usually fail fails when hot, due to materials used that have different expansion rates in the potted construction.

Look at the rev counter when cranking, if it is not reading anything then probably the CPS

Yes the car gets warm or hot and it cuts out, but restarts when cooler then 99% the CPS

Time for a CPS anyway - but understand non-Bosch can lead to short CPS life..

Like $65 aftermarket for Bosch here in US.

That should stop the "cutoff" issue - if the idle issue sticks with you then we will need to go off into other areas if it is separate 2nd/3rd issues - depending on mileage if RPM/idle stays a issue then 2nd base is MAF check, then 3rd base is throttle body..

First things 1st

Yea true. My car has a lot of mileage 267000 kilometers. I have changed the MAF before about a year ago with a Bosch one. So the only thing I am worried is that it could be the trotter body in which case I am f****** since there is no simple sensor on it that I can replace
