Frequently Asked Questions

What is the most common reason for check engine light on a 2013 Volkswagen Golf R?

• Common causes include oxygen sensor failure (P013x/P014x), catalytic converter efficiency issues (P0420), and misfires (P0300 series).
• Smaller causes such as a loose or damaged gas cap or an EVAP leak (P0455/P0442) also trigger the light and are inexpensive to fix when caught early.
• Ignoring codes like misfire or catalyst inefficiency can lead to larger repairs—fuel economy drops, higher emissions, and possible damage to the catalytic converter.
• At Nalley Volkswagen of Alpharetta, factory-trained technicians diagnose codes precisely so you avoid unnecessary parts replacement and save both immediately and long term.
