Clio DCI 65 fault

[paul_h172]

My 2002 clio DCI 65 has developed a fault, it's lost a lot of performance, cuts out while driving and has become difficult to start. Had the car on a diagnostics check, came back with two DF137 faults.
1. DF137 Rail pressure regulation function, pressure above maximum
2. DF137 rail pressure function, low flow current above maximum.

I have a feeling the fuel pressure regulator is broken, any one had similar experience or suggestions on what the problem could be?

Cheers.

It's not the fuel rail pressure sensor dying is it??

I don't know. Any way to test it?

Short of replacing the sensor I don't know.
