Did the 5000 mile oil change on my '15 CD today. I used a fluid extractor and it worked great.
I also filled the DEF using the VW/Audi 1/2 gallon DEF container with the nozzle that screws onto the filler neck. I know some guys cut off the bottom and use it as a funnel but I just refilled it with DEF I bought at Menards. The reservoir took 2 gallons of DEF and no spillage. Totally worth the 5 bucks for the 1/2 gallon bottle from VW.
Total time was 1 hour and I didn't have to go under the vehicle.
What brand / model extractor do you have?
How much oil do you actually get out using it?
We would only use it no more than every other change. It is quite an effort to remove our skid plate to get at the drain plug.
The extractor our independent has would not work.
Thanks,

I've done mine 5 times already with the Mightyvac extractor. It takes a little repositioning of the tube but I eventually get all the oil out. Only way to do oil changes IMO.
There must be something wrong with my old Griots Garage extractor as I can't get anything up out of my CD with it. I'd like to get one of the air powered ones, any suggestions?

The one I've used is Mityvac 7300 PneumatiVac. Now I've had it for years and used it many times on my Audis and have replaced the tube with ones locally obtained at a big box store. Maybe the key is finding the right tube? I also extract while warm, not hot but warm. I now have the pump one (no longer have a large compressor) which I haven't used yet but I can't imagine that the suction power is an issue. It just takes a little finesse to get the tube to the bottom of the sump.
There is an oil baffle in the CD 3.0 engine which impedes the tube from going all the way down to the bottom of the oil pan. Some people have complained that they were only able to extract half the oil using the extractor method. If you can get the extractor tub all the way to the bottom of the oil pan, they work great and make the oil change easy. I had mixed results using the extraction method. One time, I got all the oil out and the next time only about 4 liters. I gave up and now drain the oil using a fumoto oil valve. It is easy with air suspension. I raise the level to high, remove one skid plate and drain the oil using the valve.
I used the Moeller marine fluid extractor but an older model. West Marine sells a fluid extractor that looks a lot like mine. It has 2 tubing sizes but only the smaller one fits into the engine dip stick tube. The suction tube length is about 32 inches(80cm) and hits bottom with a few inches to spare. I was able to extract over 7 quarts and I put in around 7.5 quarts of new oil, the same amount as when I drained the oil with the drain plug.
Its a lot cleaner than getting under the vehicle. And while it was sucking up the oil, I did the DEF.

Is there a secret to tube positioning? I hit two points of resistance. The second one is about 2" below the first. I originally presumed the first was the baffle and the second was the bottom of the pan. I 'm using a 12V marine oil change pump and it will pump for a while and then the output drops off. When the pump output falls off, I could pull the tube out, put it back after a couple of tries to get past the baffle and it would start moving oil again. Finally I couldn't get any more oil unless I pushed past the second point of resistance. A little later, no matter what I did I couldn't get any more oil. I like the electric pump because I can hear the motor load up when it starts drawing oil. With a vacuum based system I would think it would just suck air until the vacuum was all used up and then I'd have to pump it again.
I think I got around 7 quarts out but my oil level gauge was reading about at the bottom of the OK level so I was probably down a half quart or so.
DEF fill and fuel filter siphon and I'm good for another 5000 miles.
I'd appreciate any suggestions as to how not to baby sit the drain tube to keep the oil flowing.
