Check Engine Light & Engine Diagnostics

Is your check engine light on? Lutex Auto in Newmarket helps identify engine problems with professional diagnostics, clear explanations, and a quote before any repair work begins.

Signs You Need Check Engine Light Diagnostics

Your vehicle’s check engine light can turn on for several reasons, from a loose gas cap to a problem affecting engine performance. Getting the issue checked early can help prevent a minor fault from becoming a more expensive repair.

Book an engine diagnostic if you notice any of these warning signs:

Check engine light is on: The warning light stays illuminated on your dashboard, even if the car seems to drive normally.
Flashing check engine light: The light flashes while driving, potentially indicating an engine misfire that could damage the catalytic converter. Stop driving when safe and arrange professional assistance.
Engine running rough: Your vehicle shakes, idles unevenly, or feels less smooth than usual.
Loss of engine power: Your car struggles to accelerate, hesitates when you press the gas pedal, or feels sluggish.
Poor fuel economy: You are filling up more often than usual without a clear reason.
Hard starting or stalling: Your engine takes longer to start, stalls unexpectedly, or struggles to stay running.
Unusual engine noises or smells: You notice knocking, unusual exhaust smells, or other changes in how your vehicle sounds or operates.

If your check engine light is on, don't rely on guesswork. A proper diagnostic assessment helps determine what needs attention.

What We Do: Check Engine Light & Engine Diagnostics

At Lutex Auto, our goal is to identify the cause of your vehicle's warning light and explain your options before repairs begin.

Our diagnostic process:

Listen to your concerns. We ask about warning lights, unusual noises, recent repairs, driving conditions, and any changes in performance.
Scan for diagnostic trouble codes. We use appropriate diagnostic equipment to retrieve available fault codes from your vehicle's computer.
Investigate the underlying problem. Depending on the symptoms and scan results, further inspection and testing may be needed to identify the faulty component or system.
Explain our findings. We discuss what the results mean, what repairs may be necessary, and any recommended next steps.
Provide a quote before any work. We explain the proposed repairs and costs before proceeding. No repair work begins without your approval.

A diagnostic trouble code is a starting point, not always a definitive diagnosis. Our approach focuses on identifying the likely root cause rather than simply clearing the warning light.
