Car tax rules for a 2002 car

  • Cars first registered from 1 March 2001 to 31 March 2017 are taxed by CO2 emissions band, from band A (the lowest emissions) to band M. The band is set by the CO2 figure on the V5C logbook.

These are the rules, not the amount for a specific car. Car tax check

ULEZ and clean air zones

  • Many petrol cars first registered from 2001 to 2005 already meet Euro 4, but not all of them. For a 2002 petrol car the Euro standard of that car decides.
  • Diesel cars first registered before September 2015 usually do not meet Euro 6, so a 2002 diesel usually pays the ULEZ daily charge. A few models met Euro 6 early.
  • The clean air zones in Birmingham and Bristol use the same Euro 4 petrol and Euro 6 diesel standards. The low emission zones in Scotland use them too, but enforce them with fines, not a daily charge.

The Euro standard of the car decides, not the year alone. ULEZ checker

More on the Audi TT

Read this with care. A fail rate is not a measure of build quality. How far cars are driven, how they are used and how well owners maintain them all change it, and wear items such as tyres and brake pads are common fails. Compare a model only with cars of the same age. Methodology and limits.
