4.2FSI DIY oil&filter change 20 min and 100
I know many if you don't even want to think about doing this on your own and I don't really want to either but every time I leave the car at the dealer there is always something that they mess up so want to keep the car away from them as much as possible. I would not recommend this for everyone, only if you know what you are doing. I am no mechanic but have a boat with 2 large diesel engines which out of necessity have forced a bit of knowledge and experience with these things on me.
Anyway I know there was a procedure posted here awhile back that was quite comprehensive, there is however an alternative method which does not involve lifting the car, removing the belly pan or draining the oil.
You just suck it out through the tube to the right of the filler cap, the only tool needed is a 32mm socket or a wrench for the oil filter and something to suck the oil out. It was really very easy and the only protective clothes I used was plastic gloves. It is literally a 15 min job and the OEM filter kit and high quality oil was just 100 all in all.
Some might rightly think sucking the oil out would leave more of the old oil in the engine but AUDI must have thought about this and I got all of the 7,7 ltr out (and back in) with perfect oil level readings. Incidentally this is the same procedure my dealer used on my last service, charged me 400 and the car then smelled of burned oil for 2 weeks (because the mechanic was sloppy dripping oil here and there).
The procedure would be something like this:
*Make sure the engine is at operating temp
*Park the car on level ground
*Open the hood
*Get the 32mm socket or wrench and loosen the oil filter housing cap so that air can get in and drain the filter and housing.
*Remove the cap from the dipstick tube
*Get your suction device and appropriately sized suction tube and push it down the dipstick tube, there will be a distinct stop when you have reached the bottom, pull it back up 1mm or so to make sure oil can flow.
*Start suction (it will have to run for 5 min or so depending on your equipment for this).
*Unscrew and remove the oil filter (you might want to put some paper around to catch oil dripping from the filter).
*Put the new oil filter in the housing cap.
*Reinstall the new filter.
*Make sure all of the engine oil has been removed, play with the suction tube make sure its picks up at the lowest point (should be up to 7.7 ltr but maybe just around 6.7 if your initial level was at min or under.
*Remove the tube etc and put the cap back on.
*Remove the oil filler cap and fill up with new fresh oil, I filled 7 ltrs at first and then checking the level while filling on the mmi until it just reached full which was precisely 7.7 ltr. The MMI oil level reading was a bit stupid though, I had to close the hood to get a reading.
*Start the car, take it for a spin until warm again, check for leaks and oil level, top up if needed (the oil filter housing will take a few deciliters once the oil pressure have been built)
That's it!

Oil drain in process
This is the "not used" dipstick tube on the 4.2FSI engine, I would think it similar on the TFSI engines. The white tube to the right is the one I use for sucking the oil out and where it ends is where the dipstick tube starts.
This is where the oil filter sits.

I just tried this on my 2012 w/4.2, but can only get 2-3 quarts out.
Before I started the oil change, I warmed up the car and checked the oil level via the car computer. It said the the system was full.
Now it is showing 2/3 full.
Where/why is the old oil hiding from my MightyVac? Are there windage trays in the oil pan? Please help.

I have always done mine as it is quicker than taking it anywhere. I have a 12v pump that will connect on the top of a 5 gallon bucket. Two alligator clips that I attach to the + and - studs in the engine bay. I also have a couple boats and other cars I use this on. Once a 5 gallon bucket is full I drop it at the local recycling center for free. It takes me about 20 minutes. No way I am doing this for less than 2 to 3 hours best case to take it somewhere.

Call Mighty Vac and get a longer extraction tube. The tube you have is not low enough or long enough to get to the lowest part in the pan.

Where the dip stick tube bottoms out is not at the bottom of the pan, a longer tube wont help. Audi says no-no for oil extraction for oil changes. Likely for the reason above but one could also assume that it leaves the worst oil mess to settle at the bottom of the pan over multiple changes instead of flushing it out.

It was my understanding that Audi also uses an extractor for the oil change. I have not done the 4.0T yet but on the 4.2 A8L using an extractor would get all of the oil out as I would refill based on the capacity in the manual and it would be right at the full mark on the indicator. I would usually put a 1/2 quart less in and it would be below the full mark until I put the last bit in.
It probably won’t be until the fall before I have to do an oil change on the 4.0T S8. Looks like folks here have experience with the 4.2. Has anyone been able to get all of the oil from a 4.0T from the dip stick tube?
