I finally got round to working out a 'proper' MPG figure after a journey down to Surrey and back this weekend. The trip computer was showing ~ 30 mpg after about 400 miles of motorway at around 75mph which I figured was about right. After doing a quick calculation on refuelling, the actual figure seems to be just above 25 mpg.
If such a large discrepancy normal for the UrS4 trip computer? Or have I got a leak somewhere?!
