tdiclub was a great intro for me to diesels. Unfortunately their depth of topics is pretty narrow. Best thing I ever got from there is how to replace my clutch/flywheel and contact info for a chip tuner.I guess I went backward from there because it was after I got my pd-tdi that I rebuilt my first ever engine (son's 1.6TD) and now I intend to let my wife have the 2006 and I want to rebuild another 1.6TD for myself! It's very addictive!
