“Check engine light has been on for 2 years. I've repaired just about everything possible that comes up on the code reader and nothing keeps the engine light off. I've gone to the dealer for repairs and they cannot every guarantee their work will fix the problem. Another mechanic has repaired air flow sensors, etc. And he keeps telling me it's a computer update that's needed to fix the light - not the problem with my car.”
