Aston V8 Failed emissions test
Discussion
The code reader was just a generic code reader. It did pick up that the exhaust valve circuit was inactive but that has been like that since I bought the car and has always got through all previous MOTs at the same MOT station. There had been a loose clamp on the exhaust but even after it was tightened the readings were still too high and we couldn't find any other leaks with the car up on the ramp.

But a lot does also suggest an air leak in the exhaust, or flawed test method allowing air to be sampled too
With the other readings being low it says to me you have an exhaust leak.
Get a rag of something and hold your hand over the tailpipe (without burning yourself) and see if you can head any more obvious leaks. May need another person whilst you take a look.
Only do it for a few seconds at a time though
