Control Module, Installing On Hydraulic Unit

Special tools and workshop equipment required

ESD Work Surface: VAS6613
Torque Screwdriver: VAG1624
Torx^® socket T25

CAUTION:

Excessive shaking (for example, dropping, impact) may destroy the control module. The control module must then no longer be used.

The hydraulic unit threads cannot be re-cut to secure the control module. If the threads are damaged, for example bolts are difficult to install by hand or the bolts cannot be tightened to the tightening specification. Replace the hydraulic unit.

A new control module may be installed a maximum of three times to a used hydraulic unit, to ensure that the elastic gasket seals sufficiently.

Do not install a used control module.

Surfaces must be cleaned before assembling.

-- Place the control module on the hydraulic unit without tilting.

-- Tighten the hydraulic unit and control module with the supplied new Torx^® bolts to the tightening specification, in two steps switching back and forth.

Tightening Specifications

Tighten the new Torx^® bolts in two steps, switching back and forth.
1. Step: preliminary tightening specification: 1 Nm to 1.5 Nm (to position the seal)
2. Step: final tightening specification: 2.5 Nm
