P287E Engine Disconnect Clutch Actuator Circuit/Open

EmissionsRelevant
Drive cycleNot required
Limp modePossible

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.

Likely causes

Loose, corroded or water-damaged connector at the transmission or actuator
Broken wire in the actuator feed or return line
Open coil in the clutch pressure solenoid or actuator
Failed output stage in the transmission or hybrid control module

Symptoms

  • Malfunction or transmission warning in the instrument cluster
  • Engine does not start or cannot drive the wheels
  • Reduced power or limp-home operation
