My 2006 S60 started sounding like a jet engine from the start up and continues that sound the entire time while I drive. I checked my temperature gauge and it's buried to cold. It doesn't budge, it looks inoperative. I phoned the Volvo service dept and they stated to bring it in for a $50 look. They stated that since I haven't received any warnings on the dash I should be okay until it's looked at. My question is this or could this be a quick fix ie.. fuse replacement etc?
