Hi , Hope you can help me out here , going round in circles at the minute and spent roughly £200 pounds so far, and no problem solved yet. i have a few codes here that came up on the computer. The problem is after ten minutes of driving i get a restriction on the amount of revs on the gas.
p0402- Exhaust-gas re-circulation Amount out of range
p1198- Fuel pressure regulation faulty .Has been changed.
p1113- Rail pressure sensor signal improbable Has been changed.

What on earth are you reading it with? None of those codes - even when correctly identified - have anything to do with any specific component. PSA code definitions are system specific.
P1113 EDC16C3 - Diesel high pressure regulation circuit. Rail pressure below the minimum pressure.
P1198 SID801 - Diesel high pressure monitoring. Flow regulator (VCV) at stop.
P0402 EDC16C3 - EGR circuit. Air flow measured at lower than the reference value.
So what exactly has been changed? As those codes refer to two different makers of HDi fuelling systems; which one have you got fitted?

thanks for the reply.
Readings are taken from a mechanics computer, and this is what they said needed to be changed, fuel regulated switch and a rail pressure sensor switch, which have been changed.
I also experience stalling and engineer lights comes on and thats when I get problems with low revs.
I don't know which HDI fuelling system I have, how do I find out?

I'd suggest that you take it to someone with far better equipment, technical data and, at least, a rudimentary understanding of how an HDi works.
Codes have nothing to do with replacing parts; they merely add information to the diagnostic process.
You appear to have a fuel pressure problem that's causing both the limp-home mode and the stalling. There can be many reasons for that and "poke-and-hope" parts replacement guesswork isn't going to find them.
The fuel feed to the pump; the state of the fuel filter; [any dodgy fuel been used?] the HP pump itself and the injector leak-off rate all need testing before even the outline of the problem can be established.
The EGR flow issue can be investigated once the major problem has been solved.
