180ml και για επισκευη διαφορικου (μετα απο λυσιμο δηλαδη) ειναι 200ml. επισης προβλεπεται αλλαγη της βαλβολινης στα 
1.000 χλμ και περιοδικα καθε

Complaint 
The rear-wheel drive displays premature wear in the form of leaking shaft sealing rings or an increased bearing clearance. 
Cause 
1. Increased temperature and high pressure lead to premature wear on the shaft sealing rings. 
2. Metallic abrasion, which is constantly increasing when the vehicle is in motion, significantly shortens the lifetime of 
the bearings in the rear-wheel drive. 
Measure 
For point 1: 
The gear oil capacities have changed for initial filling and when changing the oil in the rear-wheel drive. 
The new capacities: 
For initial filling: 200 ml 
For changing oil: 180 ml 
(The new RSD 05/2009 contains this modification) 
For point 2: Regular oil change in rear-wheel drive: 
At 600 mi. 
every 12,000 mi or every 2 years 
(This service interval is all ready in place)
