What is the first thing to check when the check engine light comes on?

• Start with the simple items: ensure the fuel cap is tightened — an EVAP leak from a loose cap is a common trigger.
• Check for obvious issues like low fluid levels, unusual noises, or loss of power; note any symptoms to share with the technician.
• Do not immediately clear the code without diagnosing; clearing may hide an active issue and can complicate warranty or inspection records.
• If the light is steady, schedule a dealer diagnostic; if flashing, stop driving and seek immediate dealer attention to prevent engine or catalytic converter damage.

How long does a check engine light service take?

• Initial diagnostic scans typically take 30–90 minutes, depending on whether road testing or extended live-data capture is required.
• If repairs are needed, time varies by job: sensor replacements are often same-day, while tougher repairs like catalytic replacement or hybrid-system work may take longer.
• Nalley Volkswagen of Alpharetta emphasizes efficient scheduling and accurate diagnostics to minimize downtime and avoid repeat visits that increase overall cost.
• For warranty-covered repairs, the full process must be completed at a certified dealership to ensure coverage; we will advise on estimated repair time when we present your written estimate.
