If you have the R380 box it's MTF94 although I used Comma AQF M2C-33F/G to the same spec as per the You Tube which will identify the box for you if you are not sure.
It also provides several different manufacturers oils.
Mine didn't have an inspection hole in the tunnel so I did it from underneath with a syringe and it worked ok 2.9Ltrs needed.
