Plug Sizes . . .

Hi all . . i'm sure its been mentioned here before - but anyone know what size spanna/allen key is needed to undo the refill plug on the transfer box?? Its a 95 300tdi by the way.

I've finally found where it is (after peeling all the muck away) now just looks a weird size and shape lol . .

Cheers all

its half inch square, same as your socket wrench...

you know what? i've no idea why I didn't try that I offered an allen key that kinda looked bigger than than . . well, be trying it in the morning - wifey might not like me going outside now lol . .

Cheers
