Check engine light still on. 2001 Jetta 1.8 T
Posted yesterday asking for help. No one even wants to give my question a shot?!?! Continuous problem with check engine light.... please see my posted question from yesterday
have you taken it to your parts store yet to have the codes read?they will usually do that for free.my experience with check engine lights usually ends up being a bad egr valve,bad o2 sensor,or a simple fix of a loose or bad gas cap.hope this helps!
Gas cap tightened on? Happened with my 03 if I ever got full service gas. Also, if it did go on randomly it would go off after a few starts.
I have recently had that same problem. I would unscrew the gas cap and then replace it and make sure it is on tight and secure. The light went off. I think I need a new cap, but when I do that it works!
