Check engine light 2003 Porsche boxstet
Help!!, My check engine light is illuminating, My put my old scanner on the car and it's not showing any faults. Can anyone provide me a direction i should consider. I first thought I needed to replace the 2 camshaft sensors or the oxygen sensors. I also thought I should consider replacing the AOS. I don't want to just fix other stuff if it doesn't solve my proplem. I'm a DIYer, so I hope someone can help.
