Just before Christmas I had my (excellent) local garage re-connect and re-seat the underdash wiring of my car. The car was in for them to do a more serious repair, so I thought they might as well deal with the bunches of plugs that had become disconnected and were dangling into the passenger footwell.

“Simple job! You could do it yourself,” from the car bore at the back.

Yeah, right.”

I am slightly nervous about the red light that is now continuously illuminated next to the steering wheel.
