Essentially, the Engine Control Unit (ECU) is confused. It is telling the turbo to perform a specific action, but the pressure sensor is reporting a different result. The "link" between the command and the result is broken.
The six-speed manual gearbox (standard on the DF137 90hp) is a highlight. It has a long throw but a precise feel. The clutch is light, making stop-start traffic bearable. The 1.5 dCi pulls cleanly from 1,500 rpm, meaning you rarely need to downshift on a motorway incline.
Pierre unclipped the wiring connector at the top of the accelerator pedal. He peered inside with a flashlight. df137 renault clio 15 dci link
Several factors can trigger the DF137 error code on your Renault Clio 1.5 dCi:
: The starter motor will crank the engine extensively without firing up because fuel pressure cannot meet the 230–300+ bar threshold required to activate the injectors. Essentially, the Engine Control Unit (ECU) is confused
The clamps holding the Delphi injectors can loosen, causing a “chuffing” noise (combustion gasses escaping past the injector seal). This erodes the aluminum cylinder head. Re-torque clamps every 60,000 km to 18 Nm.
Realizing this was no simple sensor glitch, the mechanic performed the "leak-off test" on the injectors. They watched as the fuel pulsed unevenly into the test bottles—evidence that the injectors were failing to hold pressure. The six-speed manual gearbox (standard on the DF137
If you are scanning your Renault Clio 1.5 dCi and have encountered the fault code , you are likely dealing with a performance issue ranging from a slight lack of power to the car entering "Limp Mode."
Excessive leakage within one or more fuel injectors can prevent the system from building necessary pressure, resulting in the DF137 code. 3. Wiring and Electrical Connections
The is a mouthful of an identifier for a surprisingly straightforward car. It is a testament to a dying breed: the affordable, ultra-economical diesel supermini.
