2002 525i Codes PO 491 & 492
I have a 2002 525i and the service engine soon light is on. The code comes up as PO 491 & 492. What does this mean and how can I fix it? My registration is incomplete because I need to have it smogged and I need that light to go out. I can't get my sticker without the smog cert. and I can't drive to work without a current sticker. And I really hope it's not too expensive because I only work 1 day a week for 3 hours at minimum wage. Please tell me this is an easy fix that can be done by anyone other than taking it to a shop.
