Electric or electronic problems in Renault Traffic

I have already solved everything.
The diagnosis was not conlitant because it had 3 alarms without reset. One of them was P0400 (exhaust gas recirculating flow).
I changed caudalimeter and was surprised to see that the engine was new. The electrical failure notice did not come out again.
For those who interest you.
Siemens' original flow cost about € 260 and I have put the Bölk compatible bought in Mister Auto. It cost me about € 80 and works perfectly. It is wearing 1 month.
