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

• Start with the basics: ensure the gas cap is tight—an unsealed cap is a common, low-cost cause of a CEL.
• Confirm you’ve refueled with the required premium unleaded fuel; incorrect fuel can trigger drivability and emissions faults.
• Look for accompanying warnings (temperature, oil pressure) and note any changes in power or noise before scheduling diagnostics.
• Book a quick scan with our service team via Service Scheduler—we’ll diagnose correctly the first time and explain cost-effective repair options.

How long does a check engine light service take?

• Initial diagnostic scans usually take 30–90 minutes depending on code complexity and required live-data checks.
• Simple fixes (tightening a gas cap, resetting codes) are quick; repairs like spark plug or sensor replacement can take a few hours.
• More involved repairs—catalytic converter or turbo work—may require parts ordering and longer shop time; we provide clear timelines and updates.
• Scheduling through Herb Chambers Alfa Romeo of Boston often reduces total time and repeat visits thanks to our factory tools, parts availability, and trained technicians.

What is the most common reason for check engine light on a 2019 Alfa Romeo Stelvio?

• Addressing these at our dealership avoids escalated damage—preventing costly repairs and preserving warranty coverage.
• If you notice rough idle, reduced power, or poor fuel economy, bring your Stelvio to our certified technicians for an accurate diagnosis.
