ULEZ exemption for older cars pre Euro4/2006

It would be interesting to see the outcome of an appeal against a ULEZ fine for a car that was compliant but had incorrectly been flagged as not.

It can only be a matter of time before that happens and a class action follows and there is then a realisation at TFL that they have no database against which to assess compliance or otherwise and the outcome will be forced refunds of all fines levied to date (since there simply is not the mechanism to do otherwise).

I have received the CoC today (very quick response from Ford )
I think it is ambiguous:

How does this work if there is no stated value for NOx?

How much of the combined HC + NOx 0.126 is NOx?  If 0.05 is HC, then the car is compliant.

I think it really needs the NOx value on its own. My car is NOx + HC of 0.187 but HC is 0.152 and NOx 0.035. So if your car follows the same proportions it should be below the limit.

Thank you - but this is the issue.
My car has been granted Type Approval at the appropriate period in time and that did not require NOx to be presented as a unique parameter - clearly so from the CoC that Ford have shared.
This new criteria is now brought in that is assessing my older car, which has full Type Approval in place, yet it is being assessed against a later set of Type Approval criteria that are never and can never be demonstrated retrospectively so I can't prove compliant but TFL cannot prove non-compliant against ULEZ criteria.

I view it as having an old car that was never fitted from new with rear seat belts.
A new car (for quite a long time now, actually) must have rear seat belts.
The MOT test requires that rear seat belts are properly functional.
The MOT test does not apply that assessment to a car that is of an age to have never have had rear seat belts.
It must be similar for an old car that never had a specific emissions criteria to be measured against.

Thanks for sharing your figures - your HC+NOx is quite a bit higher than mine but the NOx is well-within the parameters for ULEZ.
Is there any way to get the separated figure when that is not available on the CoC?

The real scandal, here, is that the relevant authorities already have - or could have - the data they need to confirm or deny compliance.  An emissions test is carried out as part of each MOT including, for diesels, a measure of NOx quantity in the exhaust.  That part of the test could be extended to petrol cars and the results, like everything else to do with the MOT, fed to the national computer.  That could then generate a yearly ULEZ compliance certificate and, to save effort, link to the ULEZ database itself.  

It doesn't have to be a problem, however TFL are choosing to make it one.

Are you sure?

AFAIK, diesel cars are visually checked that all the emission equipment is present and untampered with, that the MIL isn't on, and then they have the smoke opacity measured.

There is certainly nothing in the current MOT manual about NOx- but it is on GOV dot UK so could be totally wrong, I'll ask an MOT tester.
