My engine management light keeps coming on. I keep checking for the fault and everytime comes up the code po400 so I was told to clean egr valve but I can't locate it. Has my car got one. Someone told me that maybe I have not got one and it might be the oil preasure switch but if that was the problem I would have thought that would be a different code please can you help me

400 is an egr flow code. The valve cannot be cleaned. It would have to be replaced, if it is the proble, Passages need to be checked to be sure that there is sufficient vacuum to the valve and the passage to the manifold as well.

If there is a code, you have an egr valve. There is no motor listed so I cannot help you any further.
