brake light warning

[pastyloverA30]

2007 93 cabriolet
Warning keeps appearing
saying right hand brake light nor working
It`s working fine
Press the clear button on the steering wheel and it goes out only to come on again later.
Any ideas why? or how to reset?

Make sure the bulbs are the same both side. Also clean up the contacts.

just means the resistance is out of range - system seems to be able to predict an impending failure. it'll also trigger if it gets mismatched readings between the two sides
