Just bought a car to sell on, the nearsid rear tail light does not work. It has no power, I have ran a temporary live to the side that has no power and it is now working fine but the bulb warming light is still illuminated..? I will be looking for the issue at the weekend I suspect its obviously a broken wire, no blown fuses etc. 1. Why is the bulb warning light still on when I have piggy backed off the working tail light? Is the canbus really that intelligent? 2. Can the 3rd brake light at the top of the boot cause a bulb warning light as that doesn't work I noticed after putting my tools away! Thanks!
