Do my own, not difficult, drain. Have done several on our T2, not yet on the T3. If it's similar, get something to divert the flow from the frame. I use a cheap paper plate creased over the frame but others may do different. Also make sure to get a new crush washer and don't overtighten the plug. Good luck.
I don't recall the details, but if you're thinking of extracting go to ClubTouareg and do some research. Awhile back there was some question as to how effective that method was -- I stopped following so I don't know the outcome. The Treg definitely has a lot more oil and much deeper sump than the Jettas, Passats, etc. we might have driven before.
