Electronic Differential Lock (EDS) (Audi A6 C4)

EDS works together with ABS. EDS operates automatically, without driver intervention.

The device controls the speed of the drive wheels up to a speed of about 40 km/h using ABS sensors. The device specifically brakes the wheels that are slipping (for example, on a slippery road surface), and those with better grip receive increased traction.

The following recommendations must be followed:

When starting off, press the accelerator pedal in accordance with the road conditions. When the wheel slips due to an extreme difference in the coefficient of adhesion of the drive wheels across the width of the road surface (for example, one wheel on ice) press the accelerator pedal so that the car starts moving.

When accelerating on a road that is equally slippery across the entire width, for example in icy conditions and snow, press the accelerator pedal carefully. Particularly on front-wheel drive vehicles, there is a risk of the drive wheels slipping despite the EDS, and thus the stability of the vehicle is impaired.

EDS is switched off for a short time to prevent the disc brake of the braking wheel from overheating under unusually high load. At the same time, the car is ready for operation and has the same properties as a car without EDS.
