Hi recently bought a megane dci with a faulty turbo and had codes for the egr valve so recently fitted with a brand new Renault turbo and a new pier burg egr valve cleaned a few things out but keep getting a fault code snap on diagnosis 0468 egr circuit I even fitted the old egr and same again now I'm not bad at mechanics just not good with wiring testing I read a forum on here and tried to do the test to see if the vault age was right on the plug it seem's on my machine that it's not opening and shutting the egr I opened the loom and can't see no split wires any help would be good
