Noisy Engine At Idle And Low Speed, Please Help

[linc100]

I have a mk3 mondeo tdci mk3 2.0 with full service and 60k miles,the engine has got louder at idle,its been gradual but now noticeable,its a bit jerky on accelerationfrom stand still and the engine hesitates at at idle,it has been to a diesel specialist, who found no faults,ie codes,and would not rule out injectors,but not certain.it starts 1st time and has no smoke from the exhaust,i get around 55 to 60 miles to the gallon,but in a nutshell it sounds and feels rough,i blanked of the egr cleaned the maff sensor, changed the fuel filter, of which the specialist checked and found no debris.

now the little engine symbol on the dash has come on and stays on, ive used a rac code reader now and 0001 and 0002 show up, which if I remember was fuel pressure regulator/fuel pressure valve open. not sure if that helps or could make my engine loud and run bad, my big fear is the injectors.

if you guys can give any pointers I would be a grateful man

it could be a bad pump but to be honest, I know of some issues with the injectors on these models.

If you rev it in neutral does the car respond immediately? or is it only under load when the thing misbehaves?
