P25BDUnmetered Fuel - Forced Engine Shutdown
The engine controller commanded a forced shutdown after detecting unmetered fuel reaching the combustion chambers. Common on diesels with leaking turbo seals or cracked intercoolers that drip oil into the intake — the engine then runs on the oil and can overspeed.
