Common faults

  • Repeated blown fuses on one circuit
  • Central locking or windows dead on one side of the car
  • Battery drain flattening the car overnight
  • No communication with the SAM on diagnostics

Repairable?

// Bench verdict

Usually — water ingress is the classic killer, followed by corroded connectors and failed output drivers. Caught early, most boards are saveable: tracks rebuilt, drivers replaced, every output channel exercised on the bench. Repairing your original keeps all coding intact, which is the whole point.
