Juke Diesel Rail Pressure Sensor Fault

Sounds frustrating. I've got a Juke as well, and while mine's petrol, I had a similar issue a while back. Check engine light, rough idling. Turned out to be something with the fuel injection. I'm no expert but could it be related to the fuel rail on yours too? Was the code you got specifically pointing to the sensor, or was it more general?

The diagnostic trouble code specifically implicated the rail pressure sensor signal. In your case, was the sensor replaced, or was the issue resolved by addressing another component within the fuel injection system?

If it's specifically the sensor, then yeah, that points right to it. In my case, it wasn't the sensor itself, it was some gunk buildup in the fuel line messing with the pressure readings. But since yours is diesel and the code is specific, I reckon you're on the right track. Honestly, I'd get it checked out by a pro if you're not comfortable fiddling with the fuel system yourself. It's a pretty sensitive area, and you don't want to mess anything up further.

I had the vehicle inspected at a workshop. The rail pressure sensor was indeed defective and was replaced. The total cost was 240€. The issue is now resolved.
