leave it like it is - the XF workshop manual will explain what the EGR is for.

the benefit of it working is that the car (may) pass a strict emissions test

Other than the blank off plate, you can achieve the same effect by putting a ball bearing in the vacuum line running to the valve.

Re: xf egr valves

EGR stands for Exhaust Gas Recirculation - some exhaust gas is added to the air/fuel mix under certain conditions to reduce emissions...

Can cause trouble with economy and running hot...
