Ok tiny is going in for an mot either Friday or Monday now just doing a couple of pre mot checks couple of issues I need some help with

Prob 1 fuel filler flap switch has died it's been bodged back together by a po now in bits behind the dash. Can I get away with no switch if I just leave it open and the plug sitting on the dash? Ordering one tonight.

Prob 2 rear drivers side belt is jammed and won't pull out any clues?

Prob 3 after painting and refitting plenium Im having an issue with the throttle position sensor and high revs loosen it off and revs nicely at idle tighten up and high revs and she smells rich at the exhaust.

We will see what else the mot man picks up prob front tyre but I've a replacement in the boot, brakes she has sat for a few months.

The fuel flap should be able to be operated manually from the boot by a cable that is located nea the filler flap on the inside

I've tried to feel the cable in there no luck but using a bit of wire to short the the connector I can open the flap ok as a temp job. More worried about the idle and belt thanks tho
