Remove your rear signal light assembly (accessible in the trunk). Remove the wire harness plug and check for any visible burn marks. The wiring in the harness may have been shorted to cause intermittent signal problems.

Hello, I tried what you posted and can see burn. What do I need to replace to fix this at this point?
I have the same problem with wire burns. Anyone know how to fix??

It most cases any burn wires or connectors should be replaced as necessary. You may need to check with BMW in order to see exactly what parts are available to make the repairs.
I just had this fixed at a local mechanic and he charged me $102 to fix including materials.
On mine, it was the ground wire that was burned out on both rear light assemblies. Splice in a new bit or wire, add a blade connector and slide it onto the tab built into the metal frame of the light assembly.

There is a good possibility the fault lies within your turn signal switch. Please have this issue diagnosed by a qualified technician before replacing parts.
