Is yours an ABF?
I've got an oil leak too, seems fairly major as when I look down the back, the subframe had it pooling and it's wet under the dizzy and over the top of the gearbox..
Not sure what it is, I'm too new to the mk3 golf to know the usual places to check!!
Can you post photos of what you're seeing? I'll post some tomorrow and maybe we have the same issue lol.
Was gonna have a look under mine when I do the oil change next weekend..
But my leak is coming from under the dizzy near the 2 or 3 sensors plugged into the side of the engine and whatever it is is pissing oil out everywhere!
