If all of them have spontaneously gone out then it is likely a blown fuse. Look in the fuse box for hazard lights and pull the fuse out with the fuse puller. Then replace it with one of the same color (and probably the same number on the top). However, if your fuse is blown, there is usually a reason, which will cause it to soon blow again. There could be a short in your wires somewhere. But just replace the fuse and if it keeps happening then look into it more closely.
many possible causes, but first look at a faulty hazard button switch assembly faulty.
My research to date finds that the turn signals and hazard signals are controlled by a common relay. That relay is behind the hazard relay switch. My 2002 Audi A6 has the same symptoms you describe, and I will be removing the hazard switch to get at the relay for replacement. Good luck.
Flasher is faulty.
If the turn signals are inoperative check the hazard switch, if the hazards don't work replace the hazard switch, the signals will start working. if the hazards are ok ,the turn signal switch may be bad.
Often, a separate flasher unit is used to activate the hazard flashers. This unit might be bad, or the switch to activate the hazard flashers might be bad. answer always there are 2 flashers.one for turn signals other for hazard replace hazard flasher They have separate fuses also.

The flasher is a type of switch that regulates the turning on and off of your vehicle's turn signals and hazard signals.
Check the fuse
hazards and turn signals have separate flashers. replace flasher for turn signals
== Hazard and turn signals switch are different. Sounds like you need a new turn sig. switch. The turn signals are routed through the hazard switch. Re-check fuses 4 and 19. If they are fine, check/test the hazard switch and related wiring; if the switch is faulty, replace it. If the switch is good, check/test relay in position 12.
