EGR ?

Hello,

About 3-4 moths ago, there was some issue with my car. The engine was not able to go over 3k.
I removed my EGR valve and clean it and all was ok.

The same issue occurs today.
I got some codes :



It seems EGR again.

Can you please give me some advice about these codes ?
There may be a direct link between the first one in red and others codes ?

Thank you.
