Good news! I got the car back, and these were the items that were replaced:
Coolant leak:
Radiator hose- upper
Cooling hose- lower
Radiator
Coolant
Valve cover gasket:
Valve cover gasket set
Breather hose
Total:$1600
@OnlyGerman They did suggest that, I declined and that will be the next item on the list to replace.
As far as the ASS goes, they said the battery is at 70-80% so that can be the reason. Since it's not at 100%, it will prioritize where to send the power and will cut off extra features like ass to make sure everything else gets enough. 2nd item added to replacement list.
It's not a terrible inconvenience, I usually disable the ass feature anyway. I looked it up and as far as I understand it could be solved with some coding or battery replacement.
I love this F10 design and the car drives really well
Thank you everyone for the advice!
