The heavens opened up here on my way to the test station today and i only travelled a few miles. Longer run tomorrow..

Well the car went back after a 'very spirited' 30 mile drive. Re-test and still failed.

The Tester wouldnt "rev the nuts out of it" as its 'not policy' but suggested a more mechanically sympathetic organisation might be a better bet.

Anything obvious I should (with my limited skill set) look at? I do have VCDS lite.

Befriend a dodgy MOT tester, preferably one that does all the taxi drivers where you live

Mr Ronin

I have spoken to a 'sympathetic' MOT tester today who has managed to fit me in for Monday at the earliest.

My MoT guys gently let off the throttle after the fast idle test to allow everything to stabilise gently. They take it from ~2500-3000 rpm back to idle over about 5-10 seconds rather than just taking the foot straight off. That allows the closed-loop control to sort everything out by the time the machine takes its reading. If you just close the throttle and hit the test button the mixture can still be a bit rich and cause this sort of problem, on older cats.

Well MOT day again. I explained the above guidance and the MOT tester understood what needed to be done.

He had to adjust the main beam.

Passed with zero advisories.

Great news

My MOT tester told me his rule of thumb is whether the car is likely to kill you or somebody else, if not then it passes.

But surely, one look at the driver and it'd be a fail
