Hazards on hard braking

Hazard lights switch on by themselves under emergency braking.

Odyx Pro

What changes

Module 09: object 0A5E, byte 2, bit 6 = 1 (0D21, byte 1, bit 6 on a coded module). Under emergency braking the hazard lights come on by themselves.

Details

The 'Notbremsblinken' setting of the central electrics; a factory operation for the Q3 F3. The module sets the trigger by deceleration — normal braking changes nothing. The map comes in two variants — object 0A5E (module without long coding) or 0D21 (module with a filled long coding); Odyx uses whichever object the module has. Access code 31347; the module accepts changes only with the bonnet open. Rollback: write the object backup from the history.

  2. Odyx scans the units, recognises the car and shows what is on and what can be enabled.
  3. Open the feature card: before / after / how to check, and the change plan.
  4. Confirm the write. A backup is made automatically; put it back from the logbook any time.
