What to doArrange a workshop inspection now, and keep journeys short and local until then.

Your codes

  1. P0902 — Transmission (service now). The clutch actuator circuit is faulty, on a vehicle with an automated manual or dual-clutch transmission.

Checks to do first, in order

  1. Expect failure to engage a gear; do not rely on the vehicle for a journey you cannot abandon.
  2. Inspect the actuator connector and wiring.
  3. Have the clutch actuator and its adaptation values checked by a workshop with the right software — these systems usually need re-adapting after any work.

Codes this tool cannot interpret

How this result was reached
  • Interpretations cover standardised codes only, and describe what a code means rather than what is wrong with your specific vehicle.
  • A stored code identifies the circuit or system reporting a fault. It does not identify the failed part — a sensor commonly reports a problem it did not cause.
  • Reviewed by Project Owner on 2026-08-26.
  • This tool covers a reviewed subset of standardised codes. A code it does not recognise is reported as undocumented rather than guessed at.
