Hmm, can’t believe I missed your reply...
Yes I did test the sensor first. I’m freshly armed with a multimeter!
The car passed the MOT with a few little advisories, but nothing serious. However I got one short error free trip out before the door ajar light started to remain on at all times - probably due to my youngest Son slamming the door as if it were my Land Rover! I’m sure it would have failed soon enough anyway without his help.
Of course now the interior lights won’t turn on when any of the doors are opened. From reading other posts on here it seems like a slightly fiddly job to extract the sensor from the door, so that’ll have to wait for some better weather.
In the meantime she’s had a service, and a new distributor cap and rotor are waiting for the weekend. The fuel filter is stuck on due to rust, but I’ll soak it in wd40 a few times and hope for the best...
