    Hey guys was hoping somone can help with a problem im having.

    Occatioanlly when my S3 is hot the car wont start. If i leave it a minute it sometimes comes right.
    I checked with Vag com and found the the engine speed sensor intermittent fault. Cleared the fault register, had the start problem again and the fault message returned.

    HAS ANYONE had an intermittent speed sensor..... if so did you replace the sensor and it fixed it or was it wiring???

    Also if anyone has a picture of the location of it also that would be great!
    THANKS GUYS

    I replaced one not long ago, it's located at the back of the gearbox by one screw, need to remove airbox to get access.
    Looks like this:

    No, I had a gearbox explode on me on the M42, and it took the clutch and speedsensor with it.
    Looking from the top, standing on the passenger side, it towards the baulkhead with the airbox off... need to feel where it is as opposed to seeing it.
