    confused EGR valve

    Hello

    My first posting. 06 1.9CDTi 120 60k

    Having read up about the EGR valve problem I took mine out. It was full of carbon so flushed all this out of the metal vavle structure? Then drilled the 3mm hole in valve cap but couldn't get the assembly apart. However, I managed to free up its movement so that I could push the pin in by hand and the spring pushed it back. Put back together and fitted using old gaskets.

    Change in the car's performance was and still is amazing. However the spanner light keeps coming back on and occasionally the emissions light. So I borrowed a code reader and got P0400 EGR flow malfunction. Is this because I didin't get the valve apart and clean the spring etc? Will it matter if I leave it as it is? Should I try again and hit the plunger harder?

    Any help/advice greatly appreciated.

    Its probably stored the fault in its memory as you didn't clear it. If the fault is gone it will disappear after 25-30 starts. Give it a week or so and see if the light go out.
