I too have a 2003 v70 wagon with the airbag warning and then the dash goes out. I have checked and see that it is easily removed. I can send it out to be repaired for $350 or pick up a used one for $75 My question is if I install a used one will all of the diagnostics function or do I have to have it reprogrammed?
Ideally I would like to pop in the used one just as long as there will be no mechanical problems
