Thank you but I already scanned and the result is P3055

 

Hopefully this helps

 

Thanks. I have seen something similar - I need to investigate further, maybe clean all connectors, clear the codes and see what happens. Thanks again

 

This code points at the capacitor for start/stop in the trunk next to the battery. A common cause is water intrusion from the 3rd brake light leaking (if you find water in the spare tire well rather than the battery tub, that one's from the trunk spoiler needing a reseal).

 

Thank you, there was no water but a lot of sand (car came from FL), I used compressed air to blow the sand off all connectors and it is fixed
