I have a 1998 A4 2.8L Quattro with manual transmission. I got it in October of 1997. I would get about 24 miles to the gallon in town, and ~28 on the highway. At six months it started to drop and I regularly complained to my dealer who couldn't find a problem. One year ago, just before my warranty expired, my last complaint to the dealer indicated gas milage in town of 17-18 miles to the gallon,and highway of at most 22 if I was lucky.

Four weeks ago I was on a one week trip, and when I came back my car wouldn't start. The radio was really weak, but was getting some power. The car couldn't be jumped by a friend. I assumed it was the battery, so I took it out and went and got a new battery. The car started right up, no problem.

Other than this, I have made no modifications in driving style, or where I buy my fuel. I'm now getting 24 miles to the gallon in-town, and 28 miles to the gallon highway.

It's almost like the car got rebooted, or hard reset by the battery dying. Figure THAT out!

How are you measuring your mileage, with the computer or manually?

Yep, and you get a tps recycle.
