A diesel fuel pump will be VERY expensive. You may want them to guarantee that it will fix the fault before they replace it.

Perhaps ask them how they arrived at this decision - and what else they have already tried or would suggest trying first (preferably much cheaper things).

I have replaced the EGR on my 3.0CDTi but it was still in limp mode. All it needed was the codes to be reset.

i tried reset the but still come again,or i have the wrong software. i dont now,just i dont want expende 2.500 pounds on a new pump.

Check the plug that goes into the air flow sensor. Sometimes it can be the most stupid thing...This happened when we got our 2.2DTi serviced. They forgot to replug the EGR in...

If your car fires right up and does not cut out then it can NOT be the fuel pump.

yes it can i had one faulty before drove fine up to about 2500 rpm but had a faulty fuel pump,started first time every time just had no guts as it was constantly in limp mode,when pump was changed it was cured and back to full power

so yes it can fire up and not cut out with a faulty fuel pump,it was driven this way for over a year before it was changed

to original poster has vauxhall checked your car for split or burst vac pipes?
