It's not common it's impossible for a dealer to overwrite polestar it is an integral part of the official volvo ECU so the factory has a record of it and sends the correct software down if a re load or upgrade ECU software is carried out by a Volvo Authorised repairer..
I doubt a reload would fix a tampered with ECU as it will check the original software before the download starts ...
