Ok, just purchased a mondeo 1.8lx petrol 2002 and has a known mot failure on emmissions (don't know the numbers on latest but previous was failed on 2nd fast idle excessive on all 3 carbon monoxide, hydrocarbon and lamda). I did an error check and it showed up the egr fault p0400. I assume as there is no other errors and the engine running fine that this is probably the cause. I have removed the valve and am in the process of cleaning (not too bad) Question is would this suffice or is it a replacement job?
it would also be worth a look at the pipe work connecting the egr to make sure none of that is blocked.
