Volvo Repair: Engine System Service Urgent, volvo dealer, bozos

Question
We recently purchased a 2001 S60 with around 60K miles.  After two weeks the message above appeared.  The car has now been at a local Volvo dealer for two weeks and they cannot figure out what is wrong with the car.  Aside from the message the only thing we noticed was a slight hesitation in acceleration.  Any thoughts?

Answer
Andrew, well, I dont have the car in front of me to check out. Since this thing is all computerized, it needs to be scanned and checked out.  The bozos should just clear the modules and see if the light comes back on.  A throtle service or software upgrade may take care of the hesitation.  Where are you located?  Roger
