What would we do without Google eh? ![]() ![]() To get back on topic, my MY2013 shows a consistent 3-4mph fast. (I trust my sat nav) The speedo and the lights are poor on this model. |

I've always found that the discrepancy is a percentage and is consistent so if it's 5 over at 50 it will be 10 over at 100. On some of our freeways we have speed check readouts on electronic boards. We also have temporary speed check readouts at road work sites. These are good places to check your speedo and gps for accuracy. We also have odometer check areas on freeways, usually a 5km stretch with a sign at every kilometre. Do you not have them in the UK? My gps is pretty close to the check readouts. I have larger tyres on, 245/65/17 and they make the speedo pretty accurate. I know that 245/70/17 will actually make the speedo read slow so can be a real trap. |

Well just filled up again and did the usual check with the miles travelled and gallons used (sorry for the imperial) and have clocked over 40mpg. Driving style, type of journeys, etc. has not changed and I have been getting 36-38mpg but on the odd occasion has dropped to 34mpg. I am quite aware of my driving style and always try to minimise fuel consumption so I am wondering if the odometer or fuel pump accuracy is variable (or both come to that matter!)? Anyone else noticed a 16% difference in mpg figures? |

.[/quote] That's very good but the ones coming towards you should have a slight blue shift and significant red shift really only shows up on really distant objects due to the expanding universe and I doubt if a Freelander has ever travelled that far (especially without having a few new rear diffs). 3 x FL1 2 manual + 1 auto 5 x FL2 4 manual + 1 auto Now Discovery Sport P250 MHEV SE |
