do diesel injectors need to be matched to the ecu?

Hi everyone,

My x type diesel estate 2.2  2008 is in the process of being 'de-limp moded' by my local garage. The fault codes are all on the fuel system. They changed the solenoid on the pump as it was both looking rusty and came up faulty, but that didn't get rid of limp mode. The fuel and air filters have been changed - both clean inside, no shavings in the fuel filter. Tests showed the injectors were shot, so now a new set of injectors is being fitted for me. BUT - does the car need to have the ecu matched to the new injectors, or will they just fit OK? And if so, where can that be done? Being in a remote area on the Welsh borders I've no dealer anywhere near and with the car as it is, not driveable, that makes it awkward to get it to one.

Now, if new injectors don't solve the limp mode problem, what else is there to change? Obviously this was a cheap x type, and I desperately need an estate car to get abroad on a long trip but haven't mega bucks to buy something newer and can't afford to just give it to the dealers to 'sort out for me'.  I'd need a mortgage....
