Could the big end has gone? Did they change the oil on the service? |

They also said the computer is giving 3 faults. Maf censor, throttle body and something to do with a pick up censor.

You say theres a fault reading mentioning a pick up sensor, im just wonder if that maybe refering to the crankshaft position sensor that tells the engine when to inject fuel when the crank is in the correct position? If that has a fault the fueling might be slightly out and causing the knock? |

good place to start to me, they might have knocked something changing the oil filter around there? Hipefully thats all it is a loose wire. |

Ironically the FL2 has a knock sensor, I'm on my tablet at the mo' so can't look at Topix for its location. |
