The limited-slip differential is designated on the housing or
on the type plate with an "S".

A limited-slip differential has the following advantages:

a)

Wheel slip when leaving the ground while driving over

uneven ground is prevented.

b)

With varying levels of traction / grip, wheel slip is prevented

when setting off.

c)

When cornering at high speed, the nearside wheel does not

spin.

d)

The wheels do not spin on wet surfaces and at high

roadspeeds.

e)

The risk of slipping at high speed on variable road surfaces is

reduced substantially.

Function check while installed:

a)

Flat workshop floor.

b)

Drive left wheel of vehicle onto special tool 33 1 450.

c)

Fully release handbrake.

d)

Engage 1st gear and run engine up to speed.

e)

The limited-slip differential is functioning correctly if the

vehicle can be driven off the special tool 33 1 450.

Caution!

Slowly drive out of the fixture.
