Control Module And Hydraulic Unit, Installing
Do not remove sealing plugs at new hydraulic unit until the corresponding brake line is about to be installed.
If the sealing plugs are removed too early, brake fluid can escape. If this occurs, unit may not be sufficiently filled or adequately bled.
-- Installation is performed in the reverse order of removal.
When installing the mount, make sure the rubber insulation does not push out of the bracket. After installing, make sure the hydraulic unit and the control module are secure, otherwise malfunctions will register.
-- Remove brake pedal acuator -V.A.G 1869/2-.
-- Bleed brake system. Refer to BRAKE SYSTEM, BLEEDING
-- Enter radio code.
-- Code the ABS control module -J104- in "Guided Fault Finding".
A steering angle sensor -G85-, transverse acceleration sensor -G200- and brake pressure sensor 1 -G201- basic setting must be done.
