    Audi A5 2008 B8 Brake switch issues.

    Hi. First post here so hopefully its all done correct!

    New to VAGs and VCDS but bought a 2007 Audi A5 3.0tdi quattro and VCDS. Scanned and have a fault of
    4366 - Brake Switch (F)
    P0703 00 [044] - Electrical Malfunction
    and also
    00526 - Brake Light Switch (F)
    008 - Implausible Signal - Intermittent
    I have tried to reset these but they constantly return. I then replaced the switch with a aftermarket part. The faults remained after reset. I then replaced the switch with an OE one. Fault still remains (followed Elsawin proceedure eg do not move pedal, click in locating tabs and then rotate purple locking tabs clockwise). I checked the bulbs and all brake lights are working correctly.
    Today I got the ESP light on and the errors appear to have moved into the ABS section. Attached full scan if anyone can assist!

    Waxing pedantic: This is a 2008 model, not 2007. In fact, I don't think a 2007 model A5 exists. I'll fix the thread title.

    Have you verified all the wiring related to the brake switch?

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    Thanks for the reply. Appologies, the date on the v5 is first reg 15/10/17 and its a 57 plate so just assumed it was an 07.
    With regards to diagnosis as far as ive got is to confirm the lights work. I also looked at the control module (engine?) And checked that the ecu signal and switch signal were active on pressing the pedal (they were but iirc the ecu lagged slightly behind the switch?) Could you give a brief indication of what to check across tje 4 pins and ill check and report back.
    Really appreciate the help!

    IIRC the switch has two parts - normally open and normally closed when the pedal isn't pressed. The ECU looks for these two parts to always be "opposites".

    Did you verify fuses first & ground points + all connections, then switch tracks from end to end isolated with load light & if good change switch, if fault persists chance modules intercepting signal?
