Volkswagen Golf Emergency Brake Warning Flash

When braking in an emergency the hazard lights flash to warn traffic following behind.

This feature can be turned on and off in Vagcom/VCDS using Byte 17 Bit 0.

For the lights to flash the following parameters must be met

  • Deaceleration has to be higher then 7m/s² and
  • for a duration longer then 700ms or
  • the ABS must be active for more then 2 seconds.

Once one or both of these requirements are met the indicator lights will flash until until the paramters are no longer met.
