    a3 flashing glow plug light

    hi there.....
    i have got a 2004 1.9 tdi a3 with flashing glow plug..... now i have heard about the brake light switch causing this, but my brake lights are working fine. the car also stalls when taking foot off accelerator pedal.....has this switch got a fuel cut off incorporated for mpg while braking??? had the car plugged in and only fault was a rpm flywheel sensor out of range........had it cleared and the fault stayed off when i plugged back in again.......any suggestions would be greatly appreciated. thanks guys..........

    you "named that tune in one"
    the switch will be sending false info to the ecu.

    The switch is a dual unit, one circuit to the brake lights and the ECU and another to the ECU only as a double check for safety as the throttle is electronic so in an emergency throttle failure situation, pressing the pedal kills the throttle. What you describe is classic brake light switch failure and a fault code read should confirm this.

Nimble technicians, surely you should hang your heads in shame. Your wit works mighty wonders, has landed men on the Moon, replaced brains by computers, and can smithy a "smart" bomb. It is a crying scandal that you cannot take the time or be bothered to build us, what sanity knows we need, an odorless and noiseless staid little electric brougham.

    hi crasher
    thanks for your response
    i have had the car plugged in and the error that appered was cleared and didnt reappear.......the car could idle for a couple of min or just decide to cut out after 10 seconds.... also i have only checked the brake lights when the glow plug light was out and worked fine . th light hasnt come on since this morning.......could this be an intermittent problem
    cheers

    If the switch section that has a problem is the one the only sends a signal to the ECU, it will not affect the brake lights.
