The car had the anti pollution warning light on and had intermittent loss of power every now and then, took it to peugeot who run a diagnostic test and came up with the following, mass air flow sensor fault and egr valve fault. l replaced the mass air flow sensor and bought a egr valve but the problem is still there. At this point any advise welcome

l have been told it could be advanced electro valve in the diesel pump has anybody had this problem and how to get over it

thanks

When you replaced the parts, it is very important you remove the codes.
If you have not already, go to the dealer, remove the codes and check again.

l wonder if the diesel particulate filter is clogged?

try a different dealer, some are better than others

l had this same problem today. l bought the car second hand from a dealer he is going to look at it. if their is any thing different l will let you know
