I think you would need the Volvo specific Vida/Dice set up to get the pressure values .I have only got a multi make reader which will not go into such detail .The Vida is connected to a laptop which must have at least Windows 7 Professional on it .These kits are on ebay from various sources ,but some are hard to make work ,so i read on the forum .If you search the forum there are lots of references to these kits ,but not having one I cannot advise .
Yes ,this is what the dealers use ,but it would be infinitely useful to you too.
