The error code is P0191. Did replacing the rail pressure sensor resolve the issue for you completely? Was it difficult to replace?

Yes, P0191 confirms it. I'd advise against trying to replace it yourself unless you're very confident. It's not the easiest job. In my case I ended up just taking it to a workshop.

Thank you for the confirmation and advice. I've taken your advice and had it diagnosed and repaired at a local garage. The rail pressure sensor was indeed defective. The total repair cost was 240€. Engine performance is now back to normal.

I had similar symptoms with my Latitude. Intermittent stalling and limp mode. Check the sensor and wiring. What is the exact error code you are getting?
