If it is the MLGU 5 speed gearbox, Citroen's service box procedures give:

4. Lubrication

Oil capacity : 2,7 ± 0,3 litres.

Oil quality : TOTAL TRANSMISSION BV 75 W 80.

Checking interval : None.

Check the oil level : No check of level.

 

Fill the gearbox through the venting hole on top of the gear box.

CAUTION : It is essential to drain the gearbox and refill it with the exact quantity of oil in the event of an external leak and after a repair. 

 

They show a drain plug (30 Nm) on the differential housing and also a level plug on this housing. They  say not to use the level plug for filling or a level check due to the angle of the gear box and that the correct quantity of oil should be put in through the vent on top.

 

 

There is also a procedure for a MLUC 5 speed gear box:

3. Oil quality

Recommended oils :

• ESSO 75w80 EZL 848
• TOTAL 75w80 H 6965

4. Oil quantity

N.B. : Refill the gearbox via the air vent hole ( 1) ; Using tool [1].

Quantity of oil to be replaced :

• After draining : 2,1 litres
• After overhaul : 2,4 litres 

 

If you are not sure which gearbox you have, you could measure the quantity of oil drained out but also look at the parts diagrams using your VIN (VIS) which you can do as a free service if you register as another professional and a member of the Citroen Owners Club on the service.citroen.com site http://service.citroen.com/pages/index.jsp
