ask your Mom, she had sump nut last night.
The sump nut is on the sump or oil pan of your VW. if you jack up your car and climb underneath it from the front you'll see the sump nut on the lowest point of the engine pointing towards the back of the car and slightly down. Don't undo the sump nut/ plug with the engine warm/hot, the oil in the sump will also be hot and can scold you.
17mm bolt and nut
It is located on the sump pan under the engine. It is the large single nut at the lowest point.
if it is what i think it is there is a nut that you put a bolt in that pulls the sump down
Under The Car. Below The Engine And It Will Be A Fairly Obvious 15mm Nut That's Facing Out Towards The Back Of The Car.
Remove nut from bottom of sump.
Pretty sure its 34mm
8mm And mine are stuck fast atm!
all you do is undo the nut on the bottom of the sump and drain the oil
