P0810
Clutch Position Control Error
- Severity
- High
- Driving
- Drive only to a garage
The module commanded the clutch to a position and it did not get there. The circuit is not being blamed - this is about the clutch physically failing to do what it was told, which points at the actuator, the hydraulics or clutch wear rather than at wiring.
Possible causes
- CommonWorn clutch, past the range the actuator can compensate for
- CommonFailing clutch actuator motor
- CommonLow hydraulic fluid or air in the clutch circuit
- CommonCalibration never performed after a clutch or actuator repair
- PossibleSticking or seized release mechanism
- PossibleFaulty position sensor misreporting where the clutch is
What you might notice
- Judder or slipping when moving off
- Transmission will not select a gear
- Car rolls back on a hill because the clutch is not engaging
- Burning smell from a slipping clutch
- Transmission warning message
What to check, in order
- Assess clutch wear first. On a high-mileage automated manual, this code is very often simply a worn-out clutch, and no amount of electrical diagnosis will change that.
- Run the clutch adaptation or calibration procedure. If the code returns immediately afterwards, the fault is mechanical.
- Check the clutch hydraulic fluid level and look for leaks at the slave cylinder and pipework.
- Watch commanded against actual clutch position on the live data screen through a full cycle.
- Do not keep driving a clutch that is slipping. It destroys itself quickly and can damage the flywheel with it, which multiplies the cost of the repair.
