C5 X7 Saloon: Centre/high Brake Light Out/flickering

[Higgo]

A friend of mine was driving behind me last night and told me that my high brake light was not working (but flickering sometimes). I've not seen it myself but will get one of the kids to press the brake pedal at the weekend.

 

I've seen a few threads about water ingress for the tourer but not sure that applies to the saloon. 

 

Any idea what the problem is likely to be and is it an easy fix?

Maybe its wiring connector is loose, there is something wrong with its wiring or the light needs replacing. To remove it unclip its cover and then undo 2 screws holding the light in place and undo the electrical connector. The light part number may be 6351EA but this should be checked using your VIN but it may be a dealer only supply. Replacement time is supposed to be 12 minutes so not a big job.

 

For the MOT it might just be an advisory rather than a failure item since I think the high level brake light is not tested.

The latest MOT manual is a bit ambiguous by saying, "Additional stop lamps, over and above the mandatory requirements, must be tested. However, if you aren't sure that they're connected, you should give the benefit of the doubt."

09 C5. Traced mine back to the actual lamp which is wired in parallel with the n.s. brake light.

The hardest and most nerve racking part of the job was getting excess to the actual lamp. Then carfully sepatating the front cover to expose the leds. Turned out to be corrosion. A good clean up and all was good to go again.

Thanks all. I'll have a look at some point tomorrow afternoon to see if I can get to it.
