    Readiness: 0110 1101


    How do i get all this solved?
    I can only tell you how fault 1-6 came about, i discovered that one of the cables in the MAF connecter was shorting and burning, so i disconnected it and hooked up a VCDS cable to see what went wrong and i found this, now my question is what should i fix, because am sure that its probably one piece of electronics that manages all that that has a problem, but i don't know where to look.
    Fault 7 is missing TCU because i removed the Automatic TCU to a manual 5speed edition so that is OK, i would be glad if someone can help tell me how i can change SOFTWARE CODING: 04550 to 04555 because that is how i can get read of fault 7 (i think so could be wrong) or any method of getting read of that fault would be great.
    fault 8 i don't know but i think it could be timing issues because i did an overhaul of the engine, i could be wrong so please advise accordingly.

    HELP PLEASE....!!!
    Robin

    These sensors share wiring so there will be a short in the wire they share somewhere... you just need to trace the wring back and see if there is anything obvious.. chances are it was the MAF wiring as you mention you had an issue... have you tried clearing the codes to see if they come back?

    Fault 8 is normally due to the cambelt being out by a tooth...

    Yes i cleared everything like 5times and it still comes back, however the car moves normally but i dont know about the consumption because am sure all the affected was to do with fuel system or air system.
    I was actually thinking of just replacing the ECU and the wireloom because the MAF goes directly to the ECU (not so sure but i think).
    can it help? however i havn't got that yet.
    am going to try that that you told me and see if it i can find something.

    ECU will be fine... a lot of sensors share wiring so its just a matter of tracing it back until you find where its causing an issue... another way to do it would be to unplug a sensor at a time, clear codes and rescan to see if anything changes as it could be just one sensor bringing the others down

    ...as in no need to change the ECU... these codes are the result of faulty wiring so I would look at that first...
