I'm new here, but not brand new to the TDI world. '03 Jetta with an O1M, no mods to speak of. 160K and have done some of my own maintenance to it, had help with the timing belt. Recently changed the temp sensor to get rid of annoying codes, and the turbo actuator due to rust-through and not holding vacuum. Biltsteins and wagon springs keep my skid plate from rubbing.
