plug nut near to sump nut - what is it?
Sorry for the stupid question but...
Just changed the oil on my Audi A3 (2008) and noticed that near to the sump nut, on the underside there is another oil drain plug like an alan key (inverted nut) that is leaking slightly.
Any ideas what this plug is for?
thanks
