Left Turn Signal Turns On When Pressing Brakes

[e dubb]

I am having a weird issue with my 318is. Whenever I press the brake the left turn signal on my cluster comes on. Has anyone else ever experienced this?

Same issue. Remove bulbs from tailights, wire brush connections, reinstall .

Your left brake/turn signal has a bad ground causing the brake light to ground through the turn signal bulb filament instead of the ground. Clean everything up as Sonny suggested and check the wiring for shorts and/or corrosion as well.

I cleaned them up as Sonny suggested and all is back to normal. Thanks everyone!
