Battery change – a single disaster

Hello With our Fiat Punto Evo (199) the battery was weak a few days ago. Cars did not start. Only with multimeter tested – and to be sure also with starting aid cable the car started. -so clear case. Battery removed and new stock. The thing again installed and: nix display reported fuel barrier and various other error messages. I then tried to find out how to reset this. After unsuccessful search behind the glove compartment and disguises, then the tip that you can reset this by means of turn signals to the right and left combinations. That actually led to success. The car starts and drives again. But: All electronic helpers are still without function. These would be among others: Start & Stop, Hill holder, servo steering, ASR and also ESP.Has someone eventuel a tip on how to breathe the systems back in life? Is nevertheless really annoying, that you can not even change the starter battery without Pobleme. And I really have changed some – just not at our Fiat Bisario –
