Showing brake lamp warning
'Check left brake lamp'

However all bulbs seem to be working

What can I do?

Thanks
 
Have you recently put LED lamps in them?
If yes, that’s probably the issue.
If not, check the lampholder for corrosion, and the earth points for the cluster for corrosion.

Poor quality bulbs can cause this also ageing bulbs change their resistance value and spook the bulb out warning. Pull the bulb and see if it has any sign of darkening in the glass, this will show that it could soon fail.

The ‘ageing bulb’ thing fixed it. Replaced the bulb and the warning light went off. It seems as if the bulb was on the way out and it triggers the warning just before the bulb is finished.

. . . clever ;)
