Q: Bad turn signals

My turn signals don't work.

A: Hello. This happens al lot on this vehicle....

Hello. This happens al lot on this vehicle. The problem is typically the turn signal switch assembly. The switch contact fail internally and cause this to happen. I typically check the voltage at the switch first to verify that it is failing, but every time I have seen this on your BMW it is the switch. If you plan on having this fixed, consider using YourMechanic, to have a certified mechanic come and replace your turn signal switch if needed.
