You guys are over thinking this. Most VW/Audi/Porsche have the oil filter on top of the engine. In between the dealer servicing, I use the oil dipstick access to extract the motor oil. Yes, you will extract every bit of the oil. I have measured and actually got a few more ounces than through the oil plug. I learned this trick from an MB technician. They have been using the extraction method since the 80s. I have been doing this for the last 20 years or so. Never had to crawl under any of my VWs, Audis or Porsches. Although it is a good idea to remove the undercarriage panels periodically to inspect and clean. In case you are wondering, yes the dipstick access hole is still there with a cap on it, to the drivers (left) side of the oil filter.

 

Is there a product you can buy that will pump the oil out this way?

 

Go to West Marine and get a vacuum extractor. Mine works for all oil extraction of all garden tools, plus cars and boats.

 

I use this one, the capacity is just right for my use but double check the specs for whatever engine you use. There is a larger size if needed.

I pour the extracted oil into an empty oil container that has measurements then use that to measure how much new oil to pour in. It's always been right on after I double check the digital vehicle oil level readout.

 

Is this the capped pipe where the dipstick would have gone?


Dipstick cap?

 

Correct. Loop a zip tie through the hole in the cap so it pulls out easier and not be dropped. You can find oil extractors on Amazon. Some are manual, some are electric pump.poweted.

 

I just did my first oil change on my new to me base with 36k miles now. Compared to my 13 Cayenne S, I found the under panel much easier to remove than the Cayenne. This will likely not be the routine I will use all the time as I will probably use the extraction method for the next several changes and just do the under panel removal when I want to do a more thorough inspection of everything. It was also a much cleaner oil change than the Cayenne as that V8 holds about twice as much oil as my little 4 banger, and when I pulled the plug on the Cayenne that oil comes out hard and inevitably it would splash all over and even using an old shower curtain under the catch pan it would still get oil where I didn’t want it. With the Macan not a drip got loose. 😁
