I just signed up for the volvo forums. This my 1st time on this forum. so i have a 2002 s60 and for some reason the check engine light comes on but the weird thing is it never stays on permanently. sometimes it goes away for weeks and sometimes its just stays on. I really appreciate all of your help. thank you.

 

The check engine light is there to indicate a problem...what problem?? No one will know until the computer is scanned for codes.
