There is a board called TDIClub.com that I became a member of, and subsquently read a story about a chap in Florida who unfortunately had a semi back up onto the hood of this car to the roofline. The car was totalled but he had photos of the damage and I noticed that the interior, including leather heated electric memory seats, matching door cards were untouched. I bought a wiring harness from Germany and a buddy who at the time lived close by and I spent a November Sunday tearing out the old interior and installing the new leather, power, etc parts so that it was a "FrankenTDI". I bought all the parts, including a steel belly pan - TDIs typically come with plastic below engine covers that dont last in cold climates where ice and snow accumulate and pull them down. The ripper was the guy sold me all the parts for $500 delivered to my door, I spent probably another $250 for an OEM CD player, wired in an XM radio kit, and a gaggle of small odds and ends, and for a while she was a stunner.. then parts that were unrelated to the work we had done (ie non electrical) started to fail, and being "naked" with an untrustworthy TDI was not looking good to me..I ended up selling it for about what it cost me 3 years and 30K miles later as diesel prices were about 25-40 cents cheaper in NJ than reg or premium.. but it was a bugger to keep running..special tools needed, ie VagCom..unique anti-freeze.. My favorite part since they take a while to warm up in the interior, was installing an electric heat pump that would circulate (via an A/C plug I installed in the bumper) and heat the coolant on a timer when I knew I was going to be driving the next day. It took about 2 hours and when you got inside and fired her up it was all warm and toasty. My neighbors thought I had an electric car !

Oh and the additive I used at EVERY fill is called Power Service.

Good Luck and Happy Thanksgiving all
