I would drain it tbh.
Wont do the cat any good.
I slightly overfilled my 1.8T once and it smoked at start up 
Thanks, This is the one thing I have never understood about the 1.8t the dipstick.
What on the dipstick is max mark, is it the top kink?
Will i need a new sump plug when I drain it?
Yeah Its hasnt smoked yet and I have done about 150miles in it since.
