F10 m5 crankshaft sensor failure
Hi.
Im having a m5 f10 2012 which has been driving 110.000km in for diagnosis due to limp home mode. Car is returning fault code "160020 - crankshaft sensor: signal implausible" Crankshaft sensor was replaced due to the same errorcode 3 weeks ago, and have been driving perfectly untill now. Car ilevel is 19-03-5xx. Anyone have got any ideas? It is cutting out for a short second now and then when driving. Im pretty lost here.

RE: F10 m5 crankshaft sensor failure
Did you replace it with quality sensor? I have an experience that cheaper ones work exactly like that - cutting for few seconds first and that time increases. I had random quality issues even with BMW sensors. These observations are not specific to M5.

Service function for the replacement was also done when it was replaced. - Remote coding & programming - F 8HP45/50/70/75 ISN reset remote

RE: F10 m5 crankshaft sensor failure
From my experience I would blame the new sensor. Especially if it worked for 3 weeks.
P.S. Although faults in OEM parts are rare, I had much better luck with original Bosch/Siemens crankshaft sensors than BMW OEM. |

RE: F10 m5 crankshaft sensor failure
I had this error in my 550 which has basically the same engine.
I stripped the whole engine and replaced solenoid valves, all sensors, chains, gaskets. Even the camshaft sprokets and the steam valve shafts. Now engine runs smoothly as it should and oil consumption is zero again. It took me two weeks and 3000 Euros in spare parts. official Dealer Prince is 8500-9000 Euros. This engine is very sensitive... Hit Thanks and Reputation button if this post helped you.

Yeah well i am also afraid that the timing chain has stretched, but in thinking the misfiring is causing the inplausible signal from the crankshaft. Which will lead to a mixture faultcode. - Remote coding & programming - F 8HP45/50/70/75 ISN reset remote

RE: F10 m5 crankshaft sensor failure
Anyone got any other hints? Cant seem to figure this out, before having to check timing..

RE: F10 m5 crankshaft sensor failure
Have you inspected the harness for broken wires, scope the crank signal at the sensor and at the ECM.
How about the air gap? I believe they are sensitive and should be 0.55mm. If someone took the time to help you, the least you can do is take a few seconds and press two buttons!
