bikerwales posted a topic in Ford Fiesta ClubHi I have owned various Fiesta Diesels models for 25 years and driven them over the same route. I recently bought a 6 month old ford fiesta "econetic" 1.6 diesel edge and the fuel economy is frankly appaling. I am now getting under 40 mpg on what is an urban cycle route which is way way below the government figures, the Honest John average (85% of claimed,) and also 20% less than I used to achieve on the same route with all 3 previous fiesta diesels (which all had emission levels over that claimed for this model). It has been in for inspection under warranty twice and as there are no fault codes reported, the dealer and Ford will do nothing about it. I reckon I am now paying around £200+ a year more on fuel for this car than I would, have on my previous models. I am so incensed by this and the lack of response from the deaer (and Ford) that I am plannng to take the dealer to small claims court to claim back these extra costs. If anyone has had a similar experience I'd really appreciate their advice!
