    Ive never done it on the A4 but when I did it on my Mk4 Golf I initiated the ABS bleed process on VAG-COM which then instructed me to press and hold the brake pedal down. Doing this made the pump cut in.

    There is another way to get the pump to cut in. That's by doing an output test for the ABS system in VAG-COM. Not the right way to do the ABS bleed procedure but would at least get the pump to cut in.

    Current Car:

    A3 S-Line TDI 140bhp Sportback in Misano Red Pearl with Audi Open Sky System, Chrome Roof Rails, Full Leather, Front Armrest with Audi Phone Prep, MFSW, Cruise Control, Auto Wipers, Auto Lights, Auto Dim Mirror, Rear Parking Sensors, Bose Stereo, Privacy Glass, Ambient & Footwell Lighting and Puddle Lights.

    You sure it cuts in when you lock the brakes when driving.

    I'm sure I did an output test on mine and it worked.
