Help me please

 

Flat battery car is in protection mode. disconnect negative battery cable for 16 minutes. Charge battery fully. Replace charged battery and negative cable. IGN key in and WAIT till puters make many checks. Start car - what happens ?

You have no sig line T+C assumes America/petrol, no idea of protection/fob/etc. Best of luck.
