Hey guys, I have a slight problem... I was going around a round a bout when my check engine light suddenly came on. The car doesnt seem any different and is driving perfectly fine, I dont know what it could be and maybe you guys might have some insight. its a 96 2.8 Quattro 5spd.

 

Zero way to know without scanning the car. I don't know if they still do it in CA, but you used to be able to go to Advance Auto or Autozone and they would scan your car for free.
