show the ecu relay sometimes it happens that the gnd don t arrive to the relay due to a wire who often is broken betwen battery and radiator

if you want to be sure of your problem just show what is the relay of ecu locate the +12 and make a bridge and show if car start

bonjour , did you try a "hard reset batterie" ? it maybe a bug of the habitacle unit controle , a hard reset can debug it . recurent case for this type of cars . good luck

[manueldord]

I should do then mate?

first you have to check fault codes to know if ecu communicates or not after that there many reasons for this problem
