On both my Merc and BMW, I have been using an oil extractor for several years. Works well for cars with the oil filter on top. No jacking up cars, no mess and you get every drop out.

Any way this method can work on the TT? I'm guessing not since there is no dipstick. There's also the additional complication of this engine being a dry sump system.

Just wondering if anyone tried? Maybe there's access through the oil filler neck?

 

There is 4 places to drain the oil on a Turbo. Even if you can suck the oil out, how do you remove all of it from the bottom where some heavy metals and water may lurk? I service vehicles often in my line of work, many dry sump vehicles and often I'll see milky oil come out first on transmissions, a sign of water, also in motors and trans I sometimes notice lots of glitter (metal) in the oil when first draining from the bottom plug.

Sucking it out from the top will get the upper 95% or so but not all of it.

 

I like the idea but I would also think that draining from the bottom where all the heavy sediment resides would be the best option. Besides my opinion though, I have nothing for you.

 

I always thought draining gets more oil out but it actually doesn't. I tested this before where I extracted all the oil and then removed the drain plug. Not one drop came out! This was on my BMW.

Complication with the TT is that you have 2 reservoirs to drain, so it may not work. There's also the oil in the turbos but I don't drain those anyway. Too little to bother.

Small metal and debris may get sucked out; the suction is pretty strong.

 

The BMW engine may be designed with oil extraction in mind. I recently heard Audi was going this way for some of its engines. No drain plug. But a depression/bowl into which a suction tube would drop down into and thus remove all the oil.

While with the Turbo you can I guess extract the oil out of the tank not sure how you would get the couple of quarts or more of oil out of the engine crankcase.

Frankly I wouldn't mind using some oil extraction method to get the oil out of the oil tank. The stuff just gushes out and makes a mess of things. The oil from the crankcase not so much.

 

I'm getting ready to do an oil change on the Turbo and last time I had a quart or more overflow my drain catch pan and made a hell of a mess on my driveway. I think this time I'll drain it with the oil warm, not hot so I can modulate the gush. Then when the plug's out I'll drill and tap it for a 1/16NPT plug. Next time I'll remove the small plug and let it **** a while instead of dump.

 

instead of doing all that buy a coolant drain pan for about 6$ and let her gush

 

It just dumps it regardless of how hot the oil is. I just bought a big oil pan with a large opening up top. I still had some splatter but not too bad.

 

Maybe with the more recent models but mine is a '99, so probably not.

They use that method on boats all the time, so no real reason it couldn't work on a normal car.

It is very convenient; get the suction going, go grab a beer and you're done
