i have a really odd fault with the A3. when i indicate, the green arrow comes on as it should, and the indicator, err, indicates as it should. this will only last a few seconds when the indicator arrow stops flashing and it doesn't flash at the side repeater or the headlight either. this happens both left and right - sometimes it doesn't work at all the hazzards work fine though. any thoughts? its driving me mad, i feel like a bit of a danger with no indicators!
