I get much, much better mileage driving in the hills because it acts like a forced pulse and glide. I pulse to the top, and glide back down. The thinner air will help you get even better mileage with that TDI engine because you will have less wind resistance. The turbo will make sure your engine is fed plenty of air. You don't see black smoke coming out of your exhaust do you? That would indicate your engine isn't getting enough air for the amount of fuel it's dumping into the cylinder.
The best thing you can do is use your clutch or shift to neutral on the downhill portions. If you can't quite maintain enough speed on the downhill, just pulse a little faster than you would like to be traveling and coast until you have slowed a little slower than you want to be going.
