How do you change oil on Audi A3 2005?

Answer 1

--->To change your oil, put the front end of your car up on ramps so you can get underneath your car. Before you get underneath though, unscrew the oil cap on the top of your engine (this will allow the oil to drain much faster once you unscrew the oil pan nut underneath the car).

--->Climb under your car and remove the skid plate, it's easy to do (the skid plate blocks your access to the oil pan and oil filter, hence necessity of removing the skid plate) -- There are about 8 Allen screws holding it in.

--->Once you have the skid plate removed and out of the way, locate the oil pan, it should be aluminum and halfway between your front two tires... There is a (i believe) 19mm nut, maybe 3/4"...but that is what you unscrew to allow your nasty oil out...careful, there is a washer on that bolt that can fall into your oil drain pan when the nut comes out and oil gushes. The washer is brass and a magnet won't find it in your spent oil pan.

--->The oil filter is located halfway between your wheels, but towards the front of the car JUST behind the radiator fans. Once you find it, on the bottom of the filter housing is a cap that unscrews, unscrew it with your hands. You will see a small nipple that has a hole in the center. Put your Allen wrench in there, push IN and to the RIGHT. This will bleed the oil filter of remaining oil with less mess than just unscrewing the oil filter housing. DO THIS GENTLY BUT WITH ENOUGH FORCE TO ALLOW THE BLEEDER TO OPEN! If you break this part it is about 100 dollars and lots of time and trouble.

--->Put your new filter in (There's an o-ring that comes with your new filter--make sure old o-ring is out, and use the new one with your new oil filter). Reset the filter housing bleeder nipple to its normal position CAREFULLY! Put your new filter on, screw on the filter housing, screw on the bleeder cap.

--->Make sure you have the correct oil for your car, and fill it up with new oil. Make sure you do NOT overfill! You can destroy your engine by overfilling.

--->I usually put a half quart less than the recommended level, then check the level on the dipstick... JUST err on the side of not overfilling. Check the dipstick, if it's low, add the remaining half quart and you should be good.

--->Reattach your skid plate under your car.

--->Put your oil pan nut back in (might use some anti-seize on the bolt to avoid future problems removing it again), give it a good tightening.
