Damn Failed MOT

Good to hear there is some progress, but if you look at the wiring diagram you will see there is only one relay for both headlamp Dip beams, so if one is illuminating, the problem has to be after the relay, either the cable, the bulb, poor connection, or the Gnd.

The Gnd for each side is shared with the main beam lamp and the sidelamp, so if they are working (especially the main beam), then you should be able to assume that is sound. Testing is always a good idea. The Gnd points are m1 and m2 respectively, so each side inner wing Gnd point.

I suspect you disturbed the contact onto the Dip beam bulb which then caused it to work.

The side repeaters will be bad connections at the actual unit, or the bulb itself, which is common on cars that have been laid up.

I find that odd as well, I was behind wheel messing about with those plugs and sockets to indicator stork when that light decided to come back on, the wing indicators I am falling on the same side as you on those things, they are not a good bulb to use because of those contact points on the bulb, put it all back together today and book it in for an mot
