The 1.5 dCi was a marvel of compressed misery. Four cylinders, eight valves, a common rail injection system that operated at 1,600 bar—enough pressure to cut flesh from bone if a line failed. It was an engine that rewarded neglect with sudden, catastrophic silence. But Elara had never neglected it. She’d changed the timing belt at 240,000 km, again at 460,000. She’d replaced the turbo oil feed line before it could coke shut. She’d cleaned the EGR valve with brake cleaner and spite.
Renault Clio 1.5 dCi 2004 - Common Fuel Pressure Regulator Faults
The error code primarily indicates a Fuel Rail Pressure fault. More specifically, it points to either a pressure that is too low for engine demand or a discrepancy between the commanded pressure and the actual measured pressure. This issue is highly specific to the 1.5 dCi (K9K) engine and requires a targeted diagnostic approach to get your Clio running smoothly again.

Addressing DF137 requires a systematic approach, as the fault can stem from electrical, mechanical, or hydraulic failures. Clio DCI wont start! - ClioSport.net

is triggered when that conversation becomes corrupted, delayed, or stops entirely. Renault’s diagnostic software specifically labels this fault as "Link (Injection computer - Engine management computer)" . The keyword here is link —the digital bridge between two critical systems.

If actual pressure spikes erratically, suspect a sticky IMV valve or electrical circuit break. Step 2: Perform an Injector Leak-Back Test
The Renault Clio 1.5 dCi engine is highly popular for its fuel efficiency and long-term durability. However, it can face fuel system issues, with the being one of the most frustrating.
