Sadly, although this would seem to be a bonus for the environment, I don&#x27;t think it is.  A lot of people have been tempted into buying diesels based on the claimed fuel consumption and emission figures.  I was one of them.  However, unless you are regularly making long journeys these figures are a false economy.  I moved closer to my work and ended up making a lot of short trips in my car.  The result?  The engine&#x27;s Exhaust Gas Recycling (EGR) unit clogged up after several months which cost a fortune to replace (and of course the environmental impact of more of these units being manufactured).  The garage&#x27;s suggested fix for this was to make a weekly superfluous trip up and down the motorway in 4th gear to burn off clogged particulates (thus wasting fuel that was supposed to be saved). Other &#x27;fixes&#x27; I found on the internet were to apply a kit to bypass the EGR entirely (thus re-emitting the particles that were supposed to be cleaned up).<p>My fix?  Sell the car and go back to a guzzly petrol model.
