Thanks guys,
I'm pouring it into the hole next to the clutch with the cap you undo by hand, maybe that I'm not pouring in enough to make the level rise enough.
If it is below the min mark would I have to say pour in a 1/4 or 1/2 a litre?
There are no leaks anywhere I can see and no oil on the floor.
Will go to dealer on the weekend.
