I think they just drove it from the car park into the centre had it running for a few minutes then tested it.
Its a standard exhaust no de-cat.
I started the car up today and left idling it took 20 minutes for the fan to kick in.
The thermostat seems to be working properly.
I'll try another...
My car just failed its MOT on emissions. The results were pretty much the same across the fast idle tests and the natural idle test:-
CO% - 10.410
HC - 940ppm
Lambda - 0.694
I've checked the fault codes and had p0300. I checked and changed the spark plugs and you can see the car has been rich...
