I have a C230 2.5 Petrol Avantgarde SE Auto estate. First registered 02/2006 Mercedes Benz have informed me its Euro 4 (IV) . TFL's own website state that to be exempt from the ULEZ (ultra low emission zone) cars must be at least Euro 4 My C230 isn't exempt in the upcoming ULEZ charge in 2019 in the current congestion zone, and then the expanded ULEZ zone in 2021 (from the north circular to the south circular , basically the whole of inner London). My MB reg doc figures are: CO2: 233G/KM CO: 0.282 HC: 0.058 NOx: 0.018 I also have a 2004 Jaguar XJ6 3.0 petrol which is exempt as per the TFL website Its figures are: CO2: 249G/KM CO: 0.794 HC: 0.142 NOx: 0.046 I have asked TFL to clarify this but no one knows anything because they employ numptys who have a degree in bulls**t. How on earth can a car that isn't Euro 4 and emits twice as much across the board be exempt and one that is Euro 4 and emits half as much have to pay? I contacted the MB customer services who employ the same dullards, and they said they will give me my local MB dealers number as they could answer this (they couldn't, but their parts dept confirmed its Euro 4). Any thoughts?
