I will probably need a longer test over a few days.

On Gas 2 codes 0033, 172. it detected the missing Sensor.
codes erased.
.
Petrol only, was the same result, 2 codes, still unplugged.
codes erased.

plugged in, petrol only and same 2 codes, so I thought somehow they where still stored.
codes erased.

petrol only , a short 1 mile spin, engine still warm, no codes.

LTFT , there was no difference, I red them between each test.
idling, -24
2000 reves, -10 or lower.

I did drive for a period last year and I didn't have the engine light on, that's how I got through the mot, they switched on the gas by the emissions test
and it passed, but they didn't notice the engine light came on.
