    Hi Folks ,
    after a bit of advice from anyone with knowledge of Golf Mk4s
    Car is not starting no spark at plugs when cranking .
    I have heard from a few sources it could be a crank position sensor fault . I also heard that on this particular engine , I will have to remove gearbox, clutch and flywheel to get at it:eek: Can anyone confirm if this correct ?

    engine no is AHW282462 if it is any help . I have had a quick look down the back of the engine but it was just getting dark and could not really see anything down there .
    I would appreciate any help on this.

    It should show up on a diagnostic scan if it's at fault.

    Thanks for the reply Hal ,

    yes I need to get a scan done , I am trying to get someone to call at the moment as the car is not mobile ,

    my query above still remains, does the gearbox have to come out to get at these sensors?

    Well a quick google and I get this:
    On 1.4 and 1.6 golf mk4's that have a dual over head cam then the cranksensor is on rear of the block.

    Hal.
    Thanks for the link , look like my initial information was not correct ,
    I am getting a code read done today , so hopefully this should let me know what is the issue with the car not starting .

    The crank sensor is pretty awkward to access on them but you don't have to take out the gearbox.

    They don't give much trouble on them in any case so I reckon it is unlikely to be the cause of the problem here.

    George ,
    thanks for the reply on this, I have someone who is going to code read this today ,I will have more info after that .you say that these crank sensors do not give much trouble . Have you ever seen an issue like with a complete loss of spark and if so, what if you can remember was the root cause.

    Just in case anyone has the same issue with a MK 4 golf petrol ,

    The problem was traced to a loose connection on the plug which goes into the ignition coil . It took a while to find it , but got there in the end and car is back on the road
    thanks to all who replied on this.
