Renault TRAFIC II 2.0 Error P1425, P2425, No communication with the ECU

Hello
Since yesterday I am struggling with the following 2 problems in Renault Trafic II 2012, 2.0 DCI 115 HP:
1. The message "Check injection and check exhaust system" pops up. After connecting to TEXE, it displays the error P1425 - EGR coolant pump, controller circuit 2. Value beyond the limit.
I pulled the EGR, there was some soot, but I flushed it. Unfortunately, nothing helped. I saw under the air filter by the left lamp 2 circulation pumps, one of them had a broken wire +, after soldering, unfortunately, it did nothing. I don't know where to look for the cause.

After removing and cleaning the EGR, a second error P2502 also appeared - Battery charging flag status. Signal beyond the lower limit. I will add that this error was not there before removing the EGR.
Have any of your colleagues dealt with a similar problem?
I ordered a circulation pump from BOSCH just in case.
Thanks in advance for any advice.

A third pushup not there somewhere?

Pump topic solved, but now displays unknown error P2425.

P 2425 Exhaust Gas Recirculation Cooler Bypass Valve, So Fast.

Where to look for it? How can he look like? Do you mean the EGR valve itself?

Added after 14 [hours] 22 [minutes]:

Now another problem, when I looked into the fuse box and relays in the engine compartment with the ignition on, I pulled out the relays one by one and put them back in, the diagnostic computer stopped connecting to the ECU, it connects normally to the other components. When I try to connect to the ECU on a running engine, the car jerks and goes out and you can't start it until the OBD is disconnected.

I don't have the strength anymore, where to look for the reason?

How did you deal with error 1425? I have the same.

I turned off the EDC EGR.
