Hi, Im having problems with indicators at the moment on a 2002 A3 TDI. They come on for a few 'flashes' then stop working whether turning left or right. Sometimes they only come on for about 1 flash or 5 or 7 etc etc. Hazard lights work fine when pressed. Is it a problem with the indicator stalk and related connections or could it be something electrical ? All advice will be appreciated.
