Having some problems with the indicators on my 51 plate S3, and hoping some1 can help? when turning either direction, sometimes they flash and sometimes they dont, when u move the stalk, the indicator light comes on but won't flash, however a good whack on the dash to the left of the hazard switch, makes it start flashing!? The hazards work fine and all indicators flash as they should when arming/disarming the alarm. Wondering if maybe a dodgy flasher unit hence the dwsh whacking (if thats even where its located?) Any help greatly appreciated cheers guys!
