Check Engine Light S80 2001

Make sure all your vacuum hoses and especially the turbo and intake hoses are secure. If you replaced the air filter, it is possible the pipe connecting to the air filter housing is loose. But it sounds like the problem may have existed before that.

If all are ok, the boost sensor may be defective. I replaced one a few weeks ago on a friends car for the same problem. It is located in the plastic pipe that goes to the throttle module (ETM)
