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.
-- Bolt hydraulic unit and control module with new inner TORX® bolts supplied.
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.
When installing, make sure that rubber installation pieces are not pressed out of console.
-- Install in reverse order of removal.
-- Remove brake pedal loading device V.A.G 1869/2.
-- Bleed brake system, refer to BRAKE SYSTEM, BLEEDING
-- Enter radio code.
-- Code the ABS Control Module -J104- with the vehicle diagnostic tester in "Guided Fault Finding".
