Self Study Program 406 – DCC Adaptive Chassis Control

VAG SSP 406.This self-study programme shall explain how the DCC adaptive chassis control system works in detail. In this new system – the DCC adaptive chassis control, the suspension constantly adjusts itself to the road conditions, the driving situation and the driver’s requirements.

The rule for suspension systems has always been that increasing sportiness compromises the ride.

Adjustable shock absorbers are required to make this possible. The steering support is also adjusted in addition to the damping. The DCC adaptive chassis control is being used for the first time at Volkswagen in the Passat CC.
