Hi I have a 2013 R56 and the warning light for an exterior bulb comes on each time I start the car (goes off after a few seconds usually) .When it first came on I found that a number plate bulb was out so replaced that but the warning kept coming on. I looked on the internet and found how to check the warning code (134) which is for the right rear brake light bulb. Although the light was working I changed that bulb and the left side but still the warning comes on.Its just been MOT'd and there are no other lights out. Any thoughts - I don;t want to take to the dealer as it could be expensive and its not that important just fairly irritating!
