Try leaving it in 3rd instead of drive when driving round town and build your speed up slowly.Teflon posted a lengthy thread on this .Do a search "auto box overdrive."My 98 import 300 tdi auto can only squeeze 22 miles out of one costly gallon of juice irrespective of my driving style. It has just been serviced, de-catted, EGR removed and has more power than when I aquired it, but no better economy. Has anyone got any suggestions for improving my economy? I am currently thinking of removing the auto box, but I know this will be expensive and troublesome. Could it be an EDC problem?
I bet its crap off road though?58 plate Corsa van.
It's 2 tons and brick-shape but capable, comfortable, affordable and acceptable performance, 22 mpg is probably not bad and better than some smaller 4x4s.
