g) Differential
1. Preload fully adjustable between 50 and 300 Nm (hot)
2. Adjustment is made via the bolt on the differential housing cover –
remove screw plug in casing – turn the output flange until the
adjustment bolt is visible. Depress preload bolt with special tool
(V03 862 291 AC) and increase preload in clockwise direction. 1 Nm
on the ratchet equals approx. 10 Nm differential preload.
3. Caution: depending on the oil level and position of car, oil can
escape when the screw plug is removed.
