Cars: 740I 2000

CPS
Wow......just yesterday I called AutoHausAZ and requested a return to both CPS I purchased.

CPS codes never went away so I tried OEM and it went away. It cost me $129+tax each but it was worth it. Makes me wonder about OEM VS Non when it comes to electronics................

I'm always amazed that stuff like this happens, where you buy a new part from a reputable place and it's just plain designed wrong and doesn't work. I wonder if there is any quality checking in the process, or if they just submit some specs to a fabrication house and assume the parts will be fine? My other car is an old pickup, and while parts are plentiful and cheap, they are so cheaply made that it is common to get a bad part out of the box... and it's difficult to find replacement parts that aren't total crud. Rubber parts that fail after a few months, radiators that leak, fuel pumps that leak, if I get 2 years of life out of ANYTHING from Autozone I'm surprised.

Great info. BMA sells only the OE for $113. Autohaus has the aftermarket one as shown in that link.

i am conflicted about feeling bad for the gentleman. the number in bentley has been wrong since it came out. winfred told me that it was wrong in excess of 4 years ago. the ohmage measurement on his was correct.

Here a comment by Patrick

...the Aftermarket ones are the ones on my 750 E32 1988

Message: Other than initial DK sync I don't rev up above 4500 RPM in my normal commute. Still, the possibility that the Autohauzaz aftermarket type of Crank position sensors potential can cause engine problem is good info. This is not to bash Autohauzaz which is a good company I do business with, but just this specific part. To be fair I did not sense any engine malfunctioning when I brought the rpm up to sometimes 5300 doing the DK sync. There is usually a hesitation at around 4000 rpm the first round of sync process, but the second and third rounds saw no hesitation. My theory is that the EML only needs one round to finish the sync but BMW calls for three rounds in the procedure to ensure no misses.
