Why is my motor tax so high on my Audi A4?

Why is my motor tax 600 Euro and similar car is €280? The dealer told me it would be around €400. The plate is 151 LH 4456.

Hi Jurgen,

According to our figures, your car's CO₂ emissions (it's a 2015 Audi A4 saloon 1.8 petrol) are in the 156-170g/km range according to the old NEDC system. 

For such cars, registered before January 2021, the tax band is D, costing €600 a year. 

A car registered after that date with a WLTP rating of 151-160g/km would cost €280 a year and the €400 rate you mentioned is for cars with an emissions rating of 141-155g/km so perhaps the dealer was mistaken.
