Hello. I've got an old Volvo whose MSA 15.8 has lost its connection to the DIM the second time, and try to figure out whether I'll need to reload its software - and how I can possibly do this without a subscription to VIDA (again) and buying it (again) from Volvo. I actually don't know if it's possible after so many years, and I'm not very happy having to spend about 200 USD and days of work for diagnosis and fix every time I accidentally disconnect the battery or pull a relais withoug giving it enough time....
