hi i have just today had a small problem when selecting my left indicator. when selected it flashes as normal for a couple of seconds and then stops and then flashes fast then stops, strange. assumed it must be a relay problem. i have tried to find the relay but have discovered that its all incorporated within a siemens BSI. surely i dont have to replace this whole unit to change a relay?? i have tried changing bulbs and checked all fuses but made no difference.
