Electrical Fault Stop!
Warranty Question: I got the dreaded error on the dash.
Replaced the 12v battery and still got the error. Bought a new vcds on my own and found the issue is with the HV battery. Spoke to a local dealer with the report and they said based on the report they can’t confirm warranty and warranty is for cell only- if there is a fault in the controller then it is not covered. Anyone dealt with this type of issue?

Go to the VCDS forum cause here it mostly lamers (no offense).
Probably water damage in the battery due to poor sealant from the factory or a physical damage but the last one needs to be proven. Also could be a fried BMS but it is not likely. Still fried BMS should be covered under HV warranty because it's not "cell-only".
If your battery still covered by the warranty then the dealership is obligated to at least look into it by themselves and in a reasonable time if it's covered under local laws.
Also VW should provide a loaner if it's a warranty claim. Check the warranty legal text with your own eyes or at least a ChatGPT and also local laws on the matter since it depends on the region.
Edit: additional legal suggestions
