An external leakage is detected in the low pressure parts of the fuel supply system.
â–¶ How to fix
Look for gas leakage preferably with a sniffer. This shall be done outdoors. Seal the leakage by replacing pipes, couplings and/or hoses. Check the sensor for railpressure and temperature T134 Check the gasregulator
What you'll see
Gas leaks from the system to the atmosphere.The engine will be torque limited when rail pressure is too low.

Detection
The GSC is indicating a too large differece between actual railpressure and low-pass filtered railpressure for a too long time.
Possible cause
Small external leakage in the rail.
