My 2010 C500 has been running a bit rough lately
It seemed to hiccup a lot (as if short on fuel) on low throttle and on a quick "roll on" from a "rolled off" throttle. So I decided to run the "Sensors test" with the test pin provided on the ECU. I switched on the ignition, let the ECU run its test, then inserted a test wire in the test pin of the ECU and earthed the other end of the wire with the frame.
To my surprise I see 6 long and 6 short blinks on the ECU check light. After verifying with the ECU Error Code guide, I realise this denotes a malfunctioning of the Crank Position Sensor. There is more surprise for me, becuase in such a case, the guide states,
the engine will crank but not start however, my bike is running well otherwise, especially on open roads. Its just in the traffic situations that I am facing a lot of hiccups.
