Have recently bought a 2001 E46 320i saloon and have very erratic indicators!
They often flashes at double speed on both/either sides. I have replaced the front indicator bulbs and the front side lights too but this hasn't cured the problem. All the bulbs are working and this problem doesn't seem to happen when in hazard mode, on all other occasions when I indicate left or right they flash at double speed. They can sometimes return to normal and then go back to their crazy flashing.
Can someone please help with a solution to this irritation problem??
