AmoQ7

Hi, I’m looking to by a used 2012 Audi Q7 from a dealer and trying to establish of the car is ULEZ compliant. The Autotrader website suggests it is, but TfL have listed that it is not. I also contacted DLVA but they just said contact TfL. I contacted TfL and they have responded saying they need a conformity certificate from Audi or a Homologation certificate showing: - vehicle registration mark (VRM) - vehicle identification number (VIN) - euro standard the vehicle was manufactured to - Fuel Type - Nitrogen Oxides (NOx) value and - Particulate matter (PM) value (if diesel) What is peculiar is that it is recorded with emissions of just co2 195 g/km on the v5 which is low, also the tax bracket is only £330, this would suggest it should be ULEZ compliant? Can anyone shed any light on this please? Thanks
