2.0 tdi Gearbox Transmission oil spec & amount for GYX gearbox ?

I have found this thread 2.0 6 speed gearbox oil quantity which tells me about the HTA & HCF gearboxes, can anyone shed some light on the GYX transmission please ?

I take it that the G70 oil is the correct oil ?

I will be buying from Glasgow Audi

I actually found this site & very handy. AUDI A6/AVANT [A6] (EUROPE) 2006: GEARBOX: 30010. GEARBOX, COMPLETE; 6-SPEED MANUAL TRANSMISSION

It says 3.2 litres & G 052532A2 , but that's presumably when its first built.
