This link shows where I recall the fill plug to be.

One thing I am certain, I never removed the drive shaft.

Ok, below is the exact transmission which I have in my car.

The pictures you are referring to seem to show a different transmission with fill plug on the right. As you can see in the above link, my transmission had the fill plug on the back left (next to drive shaft).. We seem to have 35i X1s with slightly different transmissions.. Where did you acquire your X1 (your location says Germany, but the car was only sold in North America).. Did you ever have your trany rebuilt or replaced? Is your car right or left hand drive?
