I checked the Plus 8.
Rear fog light comes on only when the ignition and headlights are selected. Dip, or Main, it stays on.
I agree that MMC electronics are not the best. The Plus 8, in 4 short years, has had the PCB that carries all the warning lights, the row above the switches, and now the PCB that carries the warning lights between the fuel and temperature gauges. The first was under warranty, the second cost £90.00 fitted, inc VAT. I was pleasingly surprised.
