    10 A6 rear brakes lock up , ABS does not cut in , but live data reading lock up

    Hi , hope some one seen this before, driving along and press the brake , not even that hard , and the back wheels or sometimes just one will lock , and no matter how long its locked for the abs will not cut in nor will any lights come on the dash , no faults nor even a fault while it is happening , I have tried re coding the ecu , , its extremely dangerous , i can try and post vid of live data ,

    10 A6 rear brakes lock up , ABS does not cut in , but live data reading lock up

    Hi , hope some one seen this before, driving along and press the brake , not even that hard , and the back wheels or sometimes just one will lock , and no matter how long its locked for the abs will not cut in nor will any lights come on the dash , no faults nor even a fault while it is happening , I have tried re coding the ecu , , its extremely dangerous , i can try and post vid of live data ,

    Most likely a mechanical problem not a coding problem.

    RTFB and test verify and fix mechanical error.

    Have you replaced the rear caliper that is in drag condition and tested for sticking or for burr?

    What happens when you crimp a rubber line for stuck zone & after stuck condition has happened, did you isolate the zone by opening the bleeder to see if this is indeed a hydro-static error or if as you speculate from ABS unit & to determine hold PSI or mechanical defect?

    Thank you for posting the Auto-Scan.

    • Are the rear brakes dragging? Getting super hot from normal driving?
    • Tires all the same size/brand?
    • Can you feel the ABS pump kicking in when this happens?

    ok
    tyres same size , calipers not binding , none changed either , the rear is locking up when braking but the ecu does not engage abs pumping , nor does it create a fault , i can leave 100ft of rubber on the road and still nothing , i incorrectly coded a abs unit ion mk5 golf and created the same sanario , live data is picking everything up and still nothing

    Most ABS modules will drop the diagnostic session if you go over a certain speed. Are you ensuring you keep below this level?

    Go get the car SVM or install original coding.

    does this in or out of diagnostics , and code verified , and checked , the live data test was to check if the ecu was actually seeing the wheels locking up

    Gunt,

    Has there been recent work done on the ABS hydraulic block unit?
    I had a similar case but on a VW Golf where somebody interchanged the brake pipes connections (wrong connections) on the abs hydraulic unit from VL/VR HL/HR...so during braking the wheels lock with no abs intervention.
    Double check these connections to ensure they are right especially if there has been recent work in that area.
