i,

I had a warning light on the dash. There were 2 errors to do with egr valve, but I cannot seem to find the photo where the errors are shown. Anyway after changing the valve I now get just one error (will have to find out what it again). Most of the time it has no power, but sometimes it kicks in. My old valve had a flap bit broken and the teeth were worn out. Do you think there might be a leak and I should have been replaced the gaskets? Maybe teeth worn out in the replacement valve? By the way the replacement valve, when it was out the flap was not completely closed .. is that normal?

in pending and stored error codes there is an entry for P0404 - Exhaust Gas Recirculation Circuit Range/Performance

Thanks in advance
