Volkswagen's Start-Stop System automatically turns off the engine when the vehicle comes to a stand still. The system helps reduce emissions and fuel consumption by stopping the engine. When the accelerator is pressed again the engine will automatically kick back in and you can resume motoring as normal.
Volkswagen's Electronic Brake Distribution.
Every vehicles centre of gravity shifts forward when the brakes are applied. This increases the risk of the rear wheels locking up due to the reduction in traction. EBD uses the solenoid valves in the ABS unit to regulate braking power at the rear wheels, decreasing the chances of the rear of the vehicle swerving out under heavy braking.
