325i Crank Pulse Sensor Type- New vs. Old

[KMOSES]

I just replaced my crank pulse sensor because the cord was cracked at the sensor head. The replacement part I ordered was 12-14-1-720-852. When I replaced the old sensor with the new one, the car would not start. I put the old sensor back on and the car cranked right up. The new sensor head is all plastic vs. the old one that has a metal sensor head. My question is, has anyone used this new style and did it work properly? I know I may have received a faulty sensor because checking the resistance values between the two sensors showed a huge difference in readings. The photos show my old sensor (top) and the new one I received.

In my experience the aftermarket sensors are junk. I've seen more than one not even run the car myself.

Buy OEM BMW. It's only like $64 or so.

I am seeing that BMW part no. 12-14-1-720-852 is "No longer available" and that the new BMW number is 12-14-1-720-856 and that looks like the one shown with the plastic sensor head. What part number do you use and do the new ones from BMW have the plastic sensor head?

What was the resistance? Out of curiosity. I have one that is like 485 and I dunno if that 'll still fly. I know speck is 500-540 but will the ecu be mad at the lack of 15 ohms? Lol

The resistance of my old sensor is 533.

I have one like the plastic one, been working good

So you ordered this part from BMW and it came as the plastic style sensor?

ive used the plastic one with no issue whatsoever

The supply house where I get my Genuine BMW brand parts listed 12-14-1-720-852 as "No longer available". I then went to P_ _ican and they had three brands for 12-14-1-720-852, Facet, Vemo and Genuine BMW. All three mfgs. showed the all plastic head type. I just purchased the mid. priced one from Vemo $68.

I purchased one from my local BMW dealer and it had the metal tip. was about a year ago.
