My new-to-me E90 M3 is having intermittent low beam issues. About 50% of the time, the passenger low beam will not fire when I turn on the headlights. The other 50% of the time they work perfectly fine.

If they do fail to fire, I get the warning on the dash saying there is a low-beam malfunction. Sometimes I can "recover" by toggling the lights on/off a few times, but this is not fool-proof. There have been cases where they refuse to fire at all and I have to drive with 1 light out. In general, once they are on they stay on for the remainder of the drive, however I think once the passenger light actually turned off mid-drive when it was working fine.

There is no discoloration or dimness in the light output when they are working.

Has anyone experienced this in their car before?
