Should state it in the Audi A2 Owners Manual if you have one but mine took 4.5l
Thanks

My 2002 Tdi takes 4.25 litres of oil at each change when the filter element is also changed. The sump is drained fully with the front of the car slightly lifted. With this volume added, the oil level is at the top of the cross hatched area of the dipstick.
So there isn't a hatch to access the sump plug? I've read contrasting things on the net.
Definitely no access hatch. Engine under tray is held in place with multiple Torx screws, plus a couple of 10mm nuts under wheel arch.
Run car to operating temperature, then drop the sump plug.
