Hello all, can anyone help me as I’m pulling my hair out!! 

I had my bulb warning light come on but no bulbs out, now when I turn my lights on the drivers rear lights flash then go off. I have a Fabia monte Carlo 13reg

 

 

Have you done ,some LED rear lights modifications?It happens mostly if the OEM filament bulbs were replaced by LED's.Due to its  lower power consumption,BCM getting erratic readings whilst checking the lights.
