17911 defective rear light
« on: April 03, 2014, 11:54:47 PM »
R1150GS 2004 I have this 17911 error code and I can't clear it. Rear light works fine brake and running. Anyone seen this? Thanks

Haven't come across it but try changing the bulb and clean the internal and external contacts and check the wiring from the lamp in case it's partly chafed through.

bmw has a system in place that even if one filament is fused it will show two different brightnesses try replacing the globe

Correct!

Remove the taillight lens and check whether the individual filaments are working.
