Do you mean the car still doesn't pass MOT on emissions readings? If so, do you have a hard copy of the fault sheet indicating the values, what gases and what the passing values would be in your test area in Spain?

second Mot It seems that the probes have changed values from one inspection to another. They are the same.

I have not yet passed 3 MOTs because the flashing light fails... There is no fault in the machine.
Post a picture of the flashing warning light. I have a feeling it may be a warning of catalyst overheating.
If it is a catalyst overheating warning light and it flashes all the time, even when the engine is cold, then it is a faulty warning system.
