When your OBD2 scanner pulls up , it is essentially saying: "The ECU tried to send a data packet to the engine management system, but the response was either wrong or didn't arrive."
The good news is that the DF137 fuel pressure regulator is a part you can replace. It's accessible on the side of the high-pressure fuel pump. OEM part numbers commonly associated with this component include DF137, 9307Z523B, and 9109-903. In some cases, removing and blowing out the regulator with compressed air can help temporarily, but often complete replacement is the only long-term solution.

The 1.5 dCi is extremely sensitive to voltage drops. A weak battery (below 11.5V during crank) or a loose alternator ground strap causes the ECUs to "brown out." When voltage dips, the digital signal becomes corrupted, triggering DF137. In some cases, removing and blowing out the
The DF137 error code is a diagnostic trouble code (DTC) that indicates a problem with the engine's fuel system. Specifically, it relates to a fault in the fuel pressure regulator circuit.
Because diesel fuel systems are complex and high-pressure components can be dangerous to work on without experience, it is highly recommended to seek professional help. If you'd like, let me know:
Compare fluid levels. Any injector returning more than of fuel within two minutes is worn out and requires professional rebuilding. Step 3: Inspect the Low-Pressure Fuel Lines
