P06FE
Cold Start Diesel Intake Air Flow Control Performance
Moderate severity
What it means
During cold-start of a diesel engine the ECU controls intake airflow (e.g. anti-shudder valve, swirl flaps) to support smooth ignition. The control loop does not deliver the expected airflow - flap stuck or position offset.
Is it safe to drive?

The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
