Hello! Give me a hint Generally, the error returns at idle or near idle ... The car is super fires and runs well at high revs, if it catches the error, it is in emergency mode and max 3,000 rpm. Sometimes the error crashes right after firing DF053 - Bar pressure regulation function 2.DEF...

Hello . The error suggests a fault in the injection system. Check the pressure on the bar. Of course, first replace the fuel filter. And be sure to check the overflow for leaks.

Delphi pump? There were no filings in the old filter? 2.DEF regulator to the maximum and not enough so what is the pressure on the rail and is it undulating?

Return from the slat path? Have you changed the pressure control valve? I do not know what you diagnose it, how to clip it, see the context of the defect. Show what you have displayed there. How what, I will send you a technical note, you know - defect and repair procedure.

2def is the measured pressure too low, but from what I remember, it was also done there to adapt the pressure control valve, one of the LC procedures

Which year of the car before or after the improvement of these engines? 2def to ecu flushes the ratio of valve opening on the pump to the pressure on the rail is too low. It can be a filter, pump, valve, sensor on the rail, injected injectors lose pressure, etc. Maybe give him a trick from the oil banks and bypass the filter. Check if there are no filings in the system. Take a look if there was nothing buried in the ecu, maybe someone was looking for more horses and rummaged something

New filter and also ok on transfers ... checked ...

The pressure is good and there are hardly any deviations I was recording parameters with Clip and I cannot see any pressure fluctuations when there is an error on the board ?? hagiew ...

I did not change the valve Earlier in the first letter I wrote the error DF053 context 2.DEF - regulator open ... this is what Clip shows me ..... If you sent me this note, it would be great !!!!!!!!!!

I did not change the valve
Earlier in the first letter I wrote the error DF053 context 2.DEF - "regulator open" ... this is what Clip shows me .....
If you sent me this note, it would be great !!!!!!!!!!

Topic summary

The discussion revolves around a recurring error DF053 related to the Renault Kangoo 1.5dci, specifically indicating a bar pressure regulation function issue that limits the engine to a maximum of 3000 RPM. Users suggest that the error may stem from faults in the injection system, recommending checks on the fuel filter, pressure control valve, and potential leaks in the overflow. Despite good pressure readings, the error persists, indicating a possible need for ECU adaptation or further diagnostics on the pressure control valve and related components. The conversation highlights the importance of examining the entire fuel system, including the pump and injectors, for any obstructions or malfunctions.
