I have a 2010 xc90 3.2L with AWD and have an error code showing an internal fault in the SAS. The sensor doesn't work at all, all PIDs are frozen. Is it possible to disassemble and maybe clean the SAS? Otherwise, I can buy a new one but they said I'll need to take it in to a dealer to have the correct software loaded on it. How much should that cost and is there a way to do it myself?
