Re: MPG Reading
AH..but the garage is sorting it free of charge, was under a 6 month warranty, their trying a new fuelsender unit next week....
I'd be surprised if that fixes the problem- I suspect the figure comes from the engine control module by adding together each injection time and calculating the fuel used from that. The distance covered will be calculated from the vehicle speed, provided by the ABS control module.
Is the speedometer accurate? If not the dash could be programmed for different size tyres to those actually fitted.
Also are your own MPG calculations from full tank to full tank?
Currently in Disgusted's garage:
Renault Kangoo 1.5 dCi 70PS, LDV Sherpa 2.0 VTdi 140PS, Vauxhall Vivaro 2.0 CDTI 115PS.
