Have owned the beast for a few months now and have been using this awesome site for info. Thought I should contribute as well so I registered. I have a fully equipped shop so do everything myself. So far just maintenance( all fluids and filters, Intake manifolds off to clean, proper air/oil seperators etc). Currently running 22's and have it lowered about 1 1/2" via vagcom. Also turfed the suitcase muffler, and went straight thru to the factory tips. Next up is building a true straight thru deleting the dpf and getting a Malone tune(engine out time). Touareg currently has 148K km(90K miles), will post some pics soon.
