Jas11n started (and finished) this project a long time back; the photo above shows how it started- "missing" photos will be re-uploaded over the next few days. Covered in this project were things such as Tdi maintenance/ tweaks, 4 stud to 5 stud conversion (not using hub adaptors), HID fitment, retro fit trip computer, and a whole host of other things. Definitely a good read. Visit the forum for more details.
