Gearbox oil change

[Jokoto79]

Hi guys I'm thinking of changing the gearbox oil of my audi 8p 1.9 tdi 5 speed manual.Went to Mills and according to them I need SAE 75w-80 (GL-5). Do agree with the first specifications but I'm not sure about GL5 or GL4 is what my car needs.Can anyone help with the exact specifications please

It's a Febi Bilstein but not much on the label

I got my DSG oil from the dealers, not sure how good/bad it is compared to the stuff you've seen
