Tfl ulez confusion. I own two Hyundai getz cdx crtd,one on a 55 plate and one on a 56 plate. According to both vehicle registration documents they are one of the same, including co2 emissions. However,tfl ulez administration say the 56 plate is compliant but the 55 plate is not. Tfl ulez administration will not explain the difference and keep putting the onus on me to prove them wrong. Quite bizarre that their computer sees a difference between the same make model and engine. Any assistance with this matter will be welcomed.

 

Tfl ... transport for London
Sorry, live in the USA and have no idea what the issue is.
Hopefully someone can come along and help you.

 

Just out of curiosity, what do the vehicle stickers inside the driver's door with the vehicle info state?
There could be certain differences, and what are they?
