In generic OBD-II terms, this often translates to codes like (Overboost) or P0299 (Underboost).
If you already own a DF137, or you buy one tomorrow, here is your immediate action list:
: "Check Injection," "Stop," or a glowing "preheater" (glow plug) light often appear simultaneously on the dashboard.
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. df137 renault clio 15 dci link

While the ECU will usually store the DF137 code, the symptoms you experience can vary depending on whether the underlying issue is causing excessively high pressure, low pressure, or erratic regulation.
Both conditions will affect your engine's performance and fuel efficiency.
