Can I upgrade my Euro 5 car to Euro 6 to meet ULEZ standards?

I've just bought a 2015 Skoda Octavia 1.6L TDI CR which is considered Euro 5. However, on a recent MoT, it came out with 'Emissions too clean'. I'm wondering whether A) it's possible to have the car individually assessed to pass ULEZ compliance, or B) whether there are any small upgrades I can do to get it up to Euro 6 standards to be ultra-low emission zone (ULEZ) compliant?

Sadly, the short answer to this question is no.

Engine Euro ratings are weighted against a strict set of limits for CO2, NOX, particulate matter and many other compounds and gasses. To meet the latest Euro6 standards, a car has to be assessed in laboratory conditions - this is usually done by the vehicle manufacturer when the model is being developed.

In theory, it's possible you could adapt a car to meet Euro6. But this wouldn't be recognised by the DVLA, TfL or Skoda.
