Sorry about the movement. It's just me, myself, and I right now in this state. I now have a tripod and higher resolution camera. Too bad I didn't have it for this video :\ I would consider re-shooting it, but I sold the car.
I may have been able to get the real leather one repaired with a new panel, but I was looking for the cheapest option and the heated seat on the skin I replaced was wearing out. I ended up tossing it.
I purchased a leatherette one off ebay and it worked fine. I didn't notice any real difference in breathe-abilty. The upper seat back was still leather.
If there isn't a matching color on ebay my next place to check would be your local junkyard or
Brickyard Imported Cars not sure if they'll sell just the skin or the cushion and skin. The good news is I'm pretty sure the driver's and passenger's seat cushion and skin are interchangeable. I think you can also interchange A4, A6 seat custions and maybe Jetta. Sedans and Wagons appear to be different.
