Hi Apologies if this has been asked before but if anyone could shed some light on possible answers to rectify this annoying problem , would be greatly appreciated

Recently started after MOT which had bulbs fitted only ,

Thanks

Fitting incorrect or poorly fitting bulbs can cause lots of problems,, especially if it's the brake lights that have been changed. Get some genuine osram bulbs,, don't discount the brake light switch also,, cheapest option to try first. Do a search on here for the problem, loads of info to sift through. 2010 RRS, TDV8
