    Hi all,

    I drove my e46 318ci about 10 miles then it cut out bringing the battery light and traction light on and won't start again after about 45 mintues the car started. I got the car towed to the garage and they found these 4 error codes but doesn't know what the problem is.

    2780
    277f
    2782
    2731

    Has anyone had this fault or hane an idea what has caused this?

    2780, crankshaft sensor reference mark.
    277F, crankshaft speed sensor.
    2782, camshaft exhaust sensor.
    2731, Inlet camshaft control, function.

    To me it sounds like the chain has jumped making the cam timing go out.

    Hmm, I doubt it would start again that being the case, unless it was then running really rough!......

    Possibly the crank sensor is going haywire making the ECU think the cam sensors have gone bad too?? I had this on a car today as it happens (assuming no loud rattling from engine!!).

    Cheers for the posts.

    No theirs no rattle from engine and ran fine. My local garage had it for a week but couldn't get it to go back into fault. I will order a new crank sensor tomorrow.

    That's a good sign, from your post I was taking it that the car was still not running, .

    As mentioned earlier by Assimilator1 the likely candidate would be the crank sensor, they are known to play up when they get hot, We have had a few members on the forum who have had similar problems when the car gets warm and had a non start issue until the engine had cooled back down.

    The Car still runns at the minute, but i only drove it from the garage to my house about 2 miles and was fine. which would explain why the car started after half an hour or so after it stopped.

    cheers

    Yea failing crank sensors can be very finicky & eratic as they start to die, & at some point they will fail totally & your car will be dead!

    Certainly worth starting with a new crank sensor, hopefully you won't have more than 1 fault!......
