C0614 Right Park Brake Actuator Stuck On

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modePossible

C0614 is set when the right parking brake will not let go, or when the module cannot confirm that it has. To release, the motor runs in reverse; Advics treats the force as released when, after a minimum run of roughly 200 ms, the current has settled, and then lets the motor run on briefly to restore pad clearance. If that pattern never appears, or the motor stalls, the right side counts as stuck on. Bosch also uses current monitoring to spot abnormal behaviour and may command a release on its own. Causes are mostly mechanical: a seized piston or spindle nut, pads rusted to the disc after standing, or a jammed gearbox. ZF notes that the actuator must be wound back with a scan tool before service. Driving off overheats the right rear brake.

Likely causes

Seized caliper piston or corroded spindle nut on the right side
Pads rusted to the disc after the car stood for a long time
Jammed gearbox or damaged motor in the right actuator

Symptoms

  • Right rear brake drags; car pulls or feels held back when driving off
  • Hot right rear wheel and burning smell
  • Parking brake warning and release request not completed
