    Bleeding Bosch 5.0 ABS

    Morning all

    I've done some work on the brake system, including changing the master cylinder and reservoir, which has resulted in fault code 00259, N99 Inlet valve error
    I expect trapped air and the pump needs to cycle properly to expel it, I have bled the brakes using the standard proceedure but I am unable to bleed the ABS unit, I don't have the proper tester and Vag-com won't do it, as it's too old.

    Anyone done this by triggering the pump?
    From the attached CFD, I am looking at bridging the pump connector 8 to +12v and 5+10 to ground
    Can anyone confirm this is correct to run the pump?

    Cheers
    Andy
