The DIY oil change process I use on both our '14 Q5 2.0L and '06 A6 Avant 3.2L vehicles is to use an extractor thru the dipstick tube. With both oil filters located on the top of the engines, this process makes an oil/filter change simple and clean w/o crawling underneath the car, dropping the belly pan, and using a pan to catch the drained oil. If you use an extractor, just ensure the length of the tube is sufficiently long to reach the bottom of the crankcase.
A6Gary the extractor method is fine but make sure someone has a good look above the pan a couple of times a year.Many Gremlins can be hiding up there, suspension, various lines, leaks etc.
Guys, I found a source for the tubing should anyone need a replacement. I bought this from McMaster-Carr and it's 1/4" OD which is the max diameter that will fit our (my) VAG cars. I was having a minor issue with the tubing supplied with my extractor in that it was a bit too short for the Q5 oil pan, I needed something a few inches longer. This nylon tubing appears very similar to the product supplied with my extractor. McMaster forces you to buy 25' minimum and then there's shipping on top of that. This nylon has a Shore durometer of 80D and is somewhat more rigid than other samples I've purchased. Temp range for this nylon should be fine.
I suspect Grainger would offer similar and many will have a Grainger outlet nearby.

Caution. There have been reports of the extractor tubing failing and falling into the sump. Posters described the tubing as "Home Depot" tubing .
To be suitable for oil extraction the material must have suitable flexibility, temperature properties and resistance to oil. Beyond stating the obvious previous sentence I have no idea except that pieces of tubing in the sump is not good and risking that for small price saving is Sourcing from extractor makers may be a safe route.
