hi got a camshaft and a crankshaft code on a bmw 528i 97 replaced cam and crankshaft position sensors bought it from napa ..cleared the codes and the crankshaft code came back and it died while driving but it started back up but it keeps dying out while in driving..any suggestions?
-
Besides the codes, was your car dying before replacing the sensors? You could start by checking the sensor connection. If possible change back the sensor to see if you get the same symptoms.

Hello, will the crankshaft sensor cause my car to sputter while driving? I changed the crankshaft position sensor and the car drove very nicely. It started to stutter and stall again at about 100 miles of driving after I replaced the crankshaft sensor. I then have to hope for no red lights because soon after the sputter, my car stalls once stopped. 97 BMW 3281. If I let the car sit for a while I can get about 40 miles of driving before the stalling issue starts again. Note: Changed Cam Position Sensor and Crankshaft position sensor.

2007 BMW 328i...I had a CKP sensor circuit code (I can't remember the code number). Car would start and run for a few seconds, then shut down.
After replacing the totally dead battery, and the CKP sensor, it now starts, but runs very rough, rpms go up and down, and the car eventually stalls. The code I have now is P0335.
What should I check? Wiring is difficult to follow
.
-
Other than the Crankshaft Position (CKP) Sensor, I have not seen any other component setting the P0335 code. I recommend double checking the CKP Sensor installation.Have you tried installing the old sensor back?
