Special Tools And Workshop Equipment Required

ESD Work Surface:VAS6613
Torque Screwdriver:VAG1624

NOTE:

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

Surface must be cleaned before assembling.

The hydraulic unit threads cannot be re-cut to secure the control module. In the threads are damaged (bolts are difficult to install by hand or the bolts cannot be tightened to the tightening specification), the hydraulic unit must be replaced.

Tightening Specification

Install the new TORX^® bolts in two steps switching back and forth.
Step 1: temporary Tightening Specification: 1 Nm to 1.5 Nm (to install the seal)
Step 2: final Tightening Specification: 2.5 Nm
