New Control Module, Installing
Excessive shaking (for example dropping, impact) may destroy the control module. Control module must then no longer be used.
- Surface must be cleaned before assembling.
-- Slide all sealing rings -A- slightly over the valve dome.
-- Place control module without canting it onto hydraulic unit.
Sealing rings are then brought into their end position.
-- Install the hydraulic unit and control module with the new inner TORX® bolts diagonally according to the tightening specification.
A new control module may be installed a max. of two times to a used hydraulic unit, to ensure that the elastic gasket seals sufficiently.
Do not install a used control module.
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.
-- Install in 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 V.A.G 1869/2.
-- Bleed brake system, refer to BRAKE SYSTEM, BLEEDING
-- Enter radio code.
-- Code the ABS Control Module -J104- with the in "Guided Fault Finding".
A Steering Angle Sensor -G85-, Transverse Acceleration Sensor -G200- and Brake Pressure Sensor 1 -G201- basic setting must be done.
