Volvo Repair: 2000 s80 dash warning lights, volvo mechanics, warning lights

Question
2000 s80 non turbo..The dash warning lights/messages are constantly on, ie..SRS, anti-lock brakes, emmissions, etc...They change as you are driving..I have had this checked out by 3 different volvo mechanics and they all say that they get no faults when hooking up to the computer...Have you seen this before and any ideas/insight would be much appreciated..thanks...

Answer
Jimmy, The anti-lock is probably going to be a control unit but a code should be stored.  The S80 is a temperamental beast.  There really isnt much I can do about this car.  Those guys just have to keep working on it and Im sure they will find the code eventually.  Roger
