Now I have one of those flippy-key things like the VW and MB owners have, and saved about $35,000 on the car.
That's on my list of things to do for my Audi. Apparently the system has support for fobs, and I have instructions for coding them, but I don't actually have any fobs. So I have to go through the same process. It's an old car though, so it wasn't expensive either... just leaky.
The mechanics I've talked to say pretty much all the 4.2 liter Audis they've seen have been leaky... story of my life with bored-out versions. The 7.3 Ford is the same way.
