I tested the above yesterday and the main beam headlamps did not illuminate when required. The main beam warning lamp in the instrument display did work every time the switch was operated but the lamps did not. Today the main beam headlamps work when flashed but I still can't get them to switch on permanently when required?

What am I doing wrong?

You can't "unbreak" the broken,you can only break the unbroken to break the break of the unbroken, for me, you cannot unbreak me, for I am already broken,so you have no need to break the break because I am not unbroken.

Maybe you are not doing anything wrong.
If they work on the flash, that proves the wiring and bulbs are ok.
So switch maybe faulty or on that vehicle it has probably got a bsi type of system that may not be working correctly.
Can you activate lights and see the switch being activated with diagnostics?

No. Scanner has the function and when tested nothing happens with the lights. Clearly there is something wrong!
