P287EEngine Disconnect Clutch Actuator Circuit/Open
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- In a parallel hybrid, the engine disconnect clutch (often called K0) sits between the combustion engine and the electric motor and is opened for electric driving. P287E reports that the control module sees no plausible current path through the actuator that operates this clutch, typically a pressure control solenoid in the transmission valve body or an electric actuator. An open wire, a loose connector or a burnt-out coil are the classic triggers. No manufacturer publicly documents this exact code; Audi traces a related stuck-open fault on the A3 e-tron to the pressure valve of clutch 0 in the mechatronic unit. Without a working actuator the engine can no longer be coupled reliably, so electric-only or limp-home operation is likely. Circuit Low/High are covered by P2880/P2881.
- What you may notice
- Malfunction or transmission warning in the instrument cluster
- Engine does not start or cannot drive the wheels
- Reduced power or limp-home operation
- Likely causes
- LikelyLoose, corroded or water-damaged connector at the transmission or actuator
- PossibleBroken wire in the actuator feed or return line
- PossibleOpen coil in the clutch pressure solenoid or actuator
- RareFailed output stage in the transmission or hybrid control module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
