This oddidity eats my mind so i'm trying to find an explanation supposing that the diagram is not wrong. When you get to it try something: let it in neutral and bridge again the pins which are activating the reverse lamps but watch if the R led and dash indication are coming on too cos if they do means that the diagram is good and problem is still in the XYZ switch as the contact is weak and the bulb's load drops the voltage on that wire but the BCU is still detecting some low voltage which is enough to trigger the indications but not the lights, i double checked everything i knew about this circuit and all the information is the same that it's a single reverse wire from the switch which splits between the BCU and lamps(and SLABS or ACE if fitted) i checked ALL the related diagrams and i doubt that all are wrong and if it's so i apologize and i retract my statement that it's not the switch at fault even though it contradics all logic but at least if it's that i've learned something new. The diagram of C0294 is relevant as well, the red arrow points toward the header where the reverse lamps are connected

I will do, there's a bit of storm hitting us just now and it has been wild out there all day but as soon as this bad weather passes I will get back out to it. I will post a reply on here as soon as I can and thank you

Hello Sierraferry, I have been out to my disco today now that the storm has passed and I have done as you asked. When I select neutral all dash indications are as expected, the led lights up at the shifter and the N appears on the dash with pin one and two bridged. I have a spare XYZ switch that I'm going to check over. I will open it to check the contacts and make sure the inside is free from contamination, reseal it and fit it next week at some point. Fitting secondhand stuff is never a good idea but right now I have no choice. I will keep you posted
