2013 Ford Escape 2.0 Eco Diesel P0299 Underboost Fault - Engine Dies at Idle, No Restart Without Battery Disconnection

Model: 2013 Escape 2.0 Eco Fault Code: P0299 Posted: 2021-08-06 11:54

My 2013 Ford Escape with a 2.0L EcoDiesel engine is experiencing a P0299 diagnostic trouble code indicating underboost. The vehicle starts and runs normally at idle but then suddenly stalls when the engine reaches idle speed. It will remain running at higher RPMs, but once it drops to idle, it stops completely. No restart occurs without removing the negative battery cable and performing a reset. Initially, the issue would resolve after cooling down and driving, allowing the vehicle to start and run again. However, during a recent freeway drive, the engine died unexpectedly while driving at highway speed, and no restart was possible—only after disconnecting the battery did it reboot. This behavior suggests a potential issue with fuel pressure or turbocharger function related to the P0299 code.
