    I need some guidance. I have replaced the abs pump/accuator and accumator parts (whatever they're called) with used units. I did so because I lost power assist braking and all of the lights illuminated on the dash.

    After replacing the units, I've gone thru the various procedures in an attempt to bleed the system, reset the module and sensors, etc.

    The issue I'm having is nothing is working. I'm not getting the units to active, bleed or anything. I get the impression that there is another issue present...

    I have verified the wheel speed sensors are working and I can active the internal abs relays, but I am not getting any audible click when I test the ECB relay.

    I have attached the current reaccuring codes for more info, but I am stumped on what to do next. Any help is appreciated.

    I would suspect a cable is not seated well or more likely the brake booster (master cylinder) is not the right part given there are two different parts for a 2014 v which are both different from parts from a 2014 hatchback.

    The embossed housing number is not good enough.
