Here is how to check the manual operation of an EGR valve off a Peugeot 308 2.0 HDI 136. See how the mechanism returns to its seat with no problem. That me Is your EGR valve stuck! The spring at the top electronic part could be broken! This is how to take it apart and put it back together.This is in a response t just unbolt it and slide the egr blank in. if the egr has been on for a while it may be stuck. best way is to remove the fuel filter and the bracket for the fuel filter gives you full access. i tried doing it the easy way but dropped the blank behind the engine lol.
