Co Emissions

[Deakin]

Hi guys can anyone tell me how much they are paying for car tax on there avensis T3-S D4D i payed £77 for 6 months i was looking up the Co emissions and on one part of the Registration Certificate it says that the Co is 0.140 and on the back page it says that it is Co 155 G/KM so which is the proper reading,because it goes into a higher tax bracket the higher the emissions go.I thought the toyota avensis D4D was meant to be low emissions ?.Cheers guys
