    ESP light comes on and stays on.

    Yesterday my ESP light came on and stayed on, when I switch the car off and on again light comes on when i press the brake pedal, read the fault codes last night using Vag-Com and this is what I got:-
    Address 03 -------------------------------------------------------
    Controller: 1C0 907 379 E
    Component: ESP FRONT MK60 0103
    Coding: 0019970
    Shop #: WSC 06435
    2 Faults Found:
    00526 - Brake Light Switch-F
    008 - Implausible Signal - Intermittent
    01435 - Brake Pressure Sensor 1 (G201)
    008 - Implausible Signal - Intermittent

    I understand some of the VAG group car suffer from brake switch problems, is this a known problem on the A3, mine is a late 2000 (face lift model) A3 1.8T 5 door. Any help would be great as I don't want to just start replacing parts for the sake of it.
    A3 1.8t, Facelift, 5Door, Standard.

    Brake Pressure Sensor 1 (G201) is on the master cylinder IIRC which is prob why the ESP light has come on...

    Could be something as simple as corrosion on the plug...

    Was hoping that maybe the faulty switch could be the cause of the second fault.

    Brake pressure switch works from the movement/pressure of the master cylinder, brake switch sits on top of the pedal box... mechanically seperate and as far as I am aware are not symptomatic of each other if faulty.

    Just checked my brake lights and there not working, so I'll start with the brake switch as they only cost 10 from the stealers.
    Does anyone have a guide or any info for fitting these, especially removal of the lower dash panel which looks like it will need removing to gain access, as I don't want to damage anything,
    also I read on another site that the switches are easily broken during fitting.

    jiffi77,

    Have you fitted your brake switch yet? You might want to have a look at this thread to help with fitting. http://forums.vwvortex.com/zerothread?id=1158315
    Not sure if the fitting is the same on the A3 but it the switches should be very similar.
    Gone but not forgotten - Silver 2001 210BHP AMK, Black/blue interior, no silver/alloy mirrors, Brembo brakes, Standard LCR disc and DS2000 pads, Bilstein B8 shocks with H&R Springs.
    Present - VW 1.9TDI Passat SE
    To come - A3 Sportback BE 2.0TDI 140
