like a noob i've put too much fluid in my switchable auto, can i just undo the allen key bolt on the larger sump or is there another drain hole i'm missin?? thanks

Yes that is the drain hole.

The 2 upper marks on the dipstick represent a third of a litre.

mines over the ball shape of plastic at the top of the marker, even when cold. i know your supposed to check when warm but it expands as far as i know which means it'll go even higher up the dip stick???

Just drain some out as above until the correct level is achieved

thanks alot for the replies people

mine does not wanna budge. allen key with extension, nothin. looks too have a white ring between the bolt and sump. has someone sealed it or is it a washer???
