I need you're help with this one. I have a 06 S60 turbo with 81,000 miles on it and it suddenly lost power, it's so bad that I can barely make it up a hill at 20 mph. Does anyone have an idea of what this could be?

 

sounds like you've either lost fuel pressure (ie pressure sensor is not telling the pump to speed up) or you have some serious air restriction (crimped exhaust) or losing boost (loose/torn hose) between the turbo/intercooler/intake. BTW, best to post tech questions in the vehicle specific board to get the most views (let us know and the mod's move the thread)
