Default Engine System Service Urgent + Emission System Service Urgent

Year and model: 1999 S80 (2.9L)
Miles: 180K

Problem: Engine System Service Urgent + Emission System Service Urgent warning messages come on during normal driving on highway. The second message often disappears after shutting engine off overnight. The first message disappears less often than the first.

Observations: Car rides rough when messages and cautiontriangleappear. It seems like car is not burning on all cylinders. Messages appear to be related to driving speed and length of drive. Short 5-10 min trips do not trigger message but longer trips do. Commute42 miles roundtrip daily.

Questions: What is the cause of this? How can it be repaired? Volvo dealer cleared these messages once but they re-appeared within a day.

When the message appears your car is going into a limp mode, that's why it's riding so rough. When it does this your mechanic can pull the codes and tell you exactly what's going wrong. I don't understand why your dealer would just clear the codes without telling you what's wrong?

I highly recommend that you don't drive the car much until you find out what's wrong. You could damage your vehicle more by driving it with a system that isn't working properly.
