    B5 S4 Clutch Pedal Switch

    Does anyone know where I can buy this switch from?? I only need the threaded plunger piece and I seriously cannot find it anywhere . The threads on the switch are stripped and every time the clutch pedal comes up, it pushes the sensor out and the pedal basically comes up 8 inches passed the brake pedal

    Thats what happens when you change the master and let the pedal rest on the switch.
    The spring on the pedal is enough to jack it up.

    What is the part number? Should be right on it and easily found with a google search.

    Appears to be 811907343B
    There are only 2 things needed to make an Audi work properly - Duct tape and WD40. If it moves and it shouldn't - Duct tape. If it doesn’t move and it should - WD40.

    I know this is a super old discussion but few things. I did a 6 speed swap that it looks like you are also doing? I did blow the master first few hours of driving and had to go with a metal one due to the race clutch pressure. Right now I don't have this switch wired but I have the small black one on the clutch pedal. My car I need to push the pedal way to the floor for it to start, its not because of the switch you mention above because its not wired.

    Few questions/thoughts
    1. The small black clutch pedal switch I wired may be the wrong one and this switch is for cruise control or something. I am thinking this wiring should be on the clutch switch you show above.
    2. If this is true I wonder if the other switch is for cruise control or something else? I feel like the car hangs at RPM between shifts and I think what I read is the ECU knows when you switch gears to cut throttle, is this the possible issue or am I just insane?
