does anyone know what it means when the emergency light key flashes in slow intervals?The problem occured with A4 2.5tdi AKE motor ,year 2001,and the red triangle button lights up for five seconds and then turns off.This cycle is repeated continuously and it seems that any module can not go to sleep.this happens only when the car is stationary without the engine running.I would also like to know how can I check which module is asleep and who is awake.Thanks in advance!
