    vw jetta 2003
    Hi new here, wondering if anyone has seen something like this before.
    2003 jetta
    turned the car on today and it dies after a second.
    on the cluster the key light was on.
    in the odometer at first it says service then changes to say mileage is 651533 miles (only really at 91k)

    vag-com says i have two faults 16804 and 17978.
