Lift the Audi-100 as far as possible and secure horizontally (on supports!) or drive to the overpass.
Remove the lower protection of the engine compartment, see body chapter.
Place a container under the oil pan
Open the oil drain plug with a ring spanner. Let the oil drain. Be careful, it's hot!
If you lifted the car only from the front, then to completely drain the used oil, you must lower the car again. Make sure that the used oil container is not damaged or knocked over.
Substitute a container for used oil.
Loosen the oil filter with a wrench. With a very tightly seated filter, pierce the filter wall with a screwdriver (be careful, hot oil leaks out) and scroll through the filter.
Lightly grease the O-ring on the new oil filter. Do not use oil for this, as it can easily be mistaken for leaking oil when visually inspected.
Screw on the oil filter by hand without using any tools.
Wipe clean the oil filler screw and screw it in with a new O-ring, being careful not to damage the guide thread in the oil pan.
Pour oil (see table).
Start the engine, check for oil leakage.
