Warning Lights on start up
Hi all, I keep getting warning lights saying rear brake light failure or rear fog light failure, but having checked them they are fine, I take it there is some sort of sensor that is giving these faults? Is it something that can rectified?

I received this when I first bought my X5M... it was caused by aftermarket LED bulbs the previous owner installed. Installed stockers and the errors went away. Do you happen to have aftermarket bulbs of some sort in there?

Does "they are fine" mean that you physically opened the cover and undid both the brake and rear fog light bulbs to see if they are physically okay and don't have a burnt out filament or loose filament (if it is one of the incandescent bulbs)...or if there is arching/pitting on the contact points? Or does "they are fine" mean that you looked at the tail light assembly from the exterior with the lights turned on and someone possible pressing the brake pedal to see if the bulbs illuminate? Or does it mean you or someone was standing or following behind the vehicle and looked to see what was going on when you press the brakes or turn the rear fog lights on? If yes, did this include the 3rd (hi mount) brake light...or since the rear fog light warning comes up...the dynamic braking light bulb which comes on under extreme braking conditions (this would be the rear fog light if you don't have the rear fog light button on your headlight switch).

Bulbs
The bulbs illuminate as they should(where I have said they are fine), one of the bulb holders inside the assembly seemed to have rotted, so I purchased some new ones and replaced, but I still get the warning errors saying brake/fog light failure

Also to add, they are 'fine' if looking from the outside, so all the lights(brake, fog, high tailgate and normal lights all illuminate as they should), have replaced all the bulb holders inside the assemblies on both sides
