The warning screen keeps saying sidelight faulty, RH reversing light faulty, Fog light faulty. All the bulbs are ok and working. I took it for diagnostic and both circuits read no recorded faults.

I've taken out the rear light pods and cleaned the connector blocks and all bulb connections but not the fronts as that looks a lot more involved. The problem is still there and whilst it doesn't affect anything it is bl***y annoying to have it going off all the time. Dealers advice is predictable and potentially very expensive so does anyone have any ideas for me to try?

Thanks
