Hi peeps, my left hand combi switch has stopped working (all functions) I have checked the fuse and that's all good including its connections and housing.
Any thoughts please. Regards Kev R1200 GS LC TE 2013

Dont forget that the combi switch on BMW bikes is not directly connected to the flashers. It only send a command to the ZFE (electronic unit).

On the pre-LC models (and I suspect it's the same for the LC) there is a common wire and one wire for each function. If no buttons at all are working, the common is suspect. See the drawing for the older model, the wire numbers and color might not match but that will give you an idea.

Check if your switches operate when steering full right or full left. Hold one switch and move the bar from stop to stop (with the bike on the double stand) and see if something happens.

Then remove the side panels and tank then follow the wire from the bar to the computer, uplugging/cleaning/putting a dab of dielectric grease in each connector.
