If it's a database error, it needs fixing! I just checked both of our 2010 4.4 TdV8's and according to the official Glasgow website, they can both enter any ULEZ in Scotland.

Have I read the website correctly ref non-compatible vehicles? ie you simply can't drive them in the ULEZ, there's no fee that you can pay?

Edit: Just checked on gov.uk and the only clean air zone that I would have to pay to enter is London (in either car). Drives:
