C0916 code meaning
Active Roll Stabilisation Rear Actuator Circuit
What C0916 means
C0916 has no documented user; it is absent from every accessible list, bulletin and index. It names the rear axle actuator of active roll control. Systems with actuators on both axles split the stabilising torque between front and rear, which also lets them tune self-steering; ZF describes this for its electromechanical roll control. Faults at the rear unit therefore change balance as well as body lean. Bulletins show how carmakers handle such cases under their own codes: Mercedes updated the front and rear roll stabilisation units of 2021 GLE and GLS models whose software could display a warning not to exceed 50 mph, and Land Rover quarantined 2022-23 Range Rover and Range Rover Sport cars whose front and rear roll control modules sometimes failed to initialise, lighting an amber suspension lamp.
C0916 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor0.5 to 6 hours
- Clears after repairWhen cleared with a scanner
Symptoms of C0916
- Amber suspension warning lamp
- Speed limit advice in the cluster, more body roll and changed handling balance
Common causes of C0916
- Most likelyDamaged harness or plug at the rear stabiliser actuator, exposed to road spray
- PossibleRoll control software needing an update (Mercedes 2021060016, Land Rover N733)
- Less likelyRear actuator motor or gearbox failed
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note C0916 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about C0916
What does C0916 mean?
C0916 means "Active Roll Stabilisation Rear Actuator Circuit". C0916 has no documented user; it is absent from every accessible list, bulletin and index. It is a generic code, so it means the same on every make.
Is it safe to drive with C0916?
Drive gently and only to a workshop. With C0916 the car can go into limp mode (reduced power) to protect itself.
Will C0916 fail an emissions test?
C0916 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is C0916 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 6 hours of work. This is a job for a workshop.
Will C0916 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
