I've owned my 07 140bhp 2L TDI S-Line for approx 6 weeks now and I can't fathom how badly its doing for economy. I haven't got DIS so just working this out based on the trip computer on miles til fillup (which is fairly accurate) here's what I get: I filled up Â£20 @ 137.9 per litre of diesel. That equals approx 14.5L/3.18 Gallons of diesel. I've only managed to get 85 miles from that. That's 26.6MPG on a 2L diesel that's been driven slowly. I don't understand how that is possible? I've not gone above 2K rpm and I've hardly been in any traffic. Now I understand the cold weather is a factor but this is just ludicrous. What I found totally confusing was, before I parked up one day it was at 80miles before fillup. Then when I started it up, it shot down to 50 miles. I'm startled. Can any other owners share their experience, mpg and some advice?
