    I am new to this site and wonder if someone could point me in the right direction after spending some time trying to work this out.

    I've got a 520d 2006 and I bought this car with it overheating. I changed the head gasket got the head checked and skimmed. Got the car back together and no overheating. The car can start but the engine management light is now on and seems to have some problem coming from the engine. There is a random ping /tap noise that occurs every now and again. The car revs fine starts fine but just this horrible ping knock that happens while the car is started. I have not tested the car out since changing the cylinder head due to this noise.

    If anyone can shed some light I would appreciate any help as I've had the car for a year now trying to sort out this issue in my spare time with no luck now.

    Thanks

    4212 dde glow plug
    4222 dde glow plug
    4a27 dde intelligent battery sensor
    3f31 dde rail - pressure
    4191 dde charge - air pressure actuator
    3f57 dde charge air pressure controller
    4b90 dde rail pressure monitoring

    Also on removing the camshafts more than once i noticed on part number 11317790599 (camshaft sprocket) there was a hairline crack on the sprocket. I changed this from BMW and when taking the new one off on a different occasion after starting the car only a few times it has 3 hairline crack in different places. I am wondering if this big crack / knock is affecting this sprocket maybe a timing issue ???
