Update:

It was problem with the striped wire that made contact with the engine compartment (information from my mechanic). Car now runs and starts normal. So if anyone has same code make sure that all the wires are OK.

If I helped, press thankyou

The diag code said you exactly that.
I dunno why you've started chasing gremlins without checking the basics..
