P287F concerns the actuator of the clutch that couples the engine to the electric motor of a parallel hybrid. The circuit is not broken; instead, the electrical feedback (current, voltage or duty cycle) does not match what the control module expects for its command, or the clutch reacts to the command differently than the model predicts. Rising coil resistance, a sticking valve, contaminated fluid or wrong adaptation values can cause this. No manufacturer documents P287F publicly. Audi shows how closely software and hydraulics interact here: for slip faults on the Q5 and A7 plug-in hybrids it prescribes a software update, a fluid level check, a hydraulic test and a touch point adaptation of the clutch. Open circuit and short faults belong to P287E, P2880 and P2881.

Likely causes

Clutch solenoid or actuator with drifting resistance or sticking spool
Low, aged or contaminated transmission fluid
Lost clutch adaptation values or outdated control software
High contact resistance at connector pins

Symptoms

  • Jerky or delayed engine engagement when switching from electric to hybrid mode
  • Transmission warning, sometimes only intermittently
  • Limited hybrid functions or limp-home operation
