Frequently Asked Questions

What is the most common reason for check engine light on a 2025 Alfa Romeo Giulia?

• Loose or damaged gas cap is the simplest and most frequent cause — it can trigger EVAP system codes.
• Faulty oxygen sensors or air/fuel mixture issues often follow; these affect emissions and fuel economy.
• Ignition misfires (spark plugs, coils) are common on turbo engines and can generate immediate driveability concerns.
• More serious items like catalytic converter degradation may appear if maintenance is deferred.
• Bring your Giulia to Herb Chambers Alfa Romeo of Millbury for a quick scan; warranty-covered repairs must be done at a certified dealership.

What does it mean when the check engine light comes on in a 2025 Alfa Romeo Giulia?

• It indicates the vehicle’s onboard diagnostics detected a fault in emissions, engine, or powertrain systems.
• Codes range from minor issues (EVAP leaks) to urgent conditions (misfires that can damage the catalytic converter).
• If the light is steady, the car may be driven carefully to the dealership; flashing indicates an active misfire and higher risk.
• Our factory-trained technicians use OEM tools to read and interpret codes specific to the Giulia’s 2.0L turbo inline-4.
• Repairs covered by warranty must be performed at a certified dealership to preserve coverage and ensure long-term savings.

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

• Check the gas cap: ensure it’s tight and undamaged — a quick fix that often clears EVAP fault codes.
• Verify fuel type: the Giulia requires premium unleaded; incorrect fuel can trigger performance and emissions warnings.
• Note any new symptoms — reduced power, rough idle, or unusual noises — and report them to service advisors.
• If the light remains, schedule a diagnostic with Herb Chambers Alfa Romeo of Millbury; certified diagnostics protect warranty rights and avoid long-term costs.

How long does a check engine light service take?

• Initial scan and code retrieval typically take 15–30 minutes with our OEM diagnostic tools.

• Choosing Herb Chambers Alfa Romeo of Millbury often saves you time and money: we stock parts, offer efficient scheduling, and our factory-trained techs resolve issues faster than many independents.
