Turn Signal Mechanism Disassembly

This site may earn commission on affiliate links.
I have a 2019 M3 running 2023.44.30.14.

I find that 90% of the time the first detent position on the turn signal mechanism doesn’t work when turning left, and the signal acts as though it is in the second detent position. Turning right, both the first and second detent positions work perfectly/as expected.

Does anyone know if disassembling the turn signal control and cleaning any contacts would fix this problem, and if yes, are there any videos that show how to do this?

Thank you.
