Frequently Asked Questions

What is the most common reason for check engine light on a 2025 Mercedes-Benz CLE?

• Common causes include ignition misfires (spark plugs, coils), an EVAP system leak (loose gas cap or purge valve), and catalytic efficiency codes.
• Left unattended, misfires can damage the catalytic converter and lead to far higher repair costs and reduced fuel economy.
• Our factory-trained technicians at Park Place Motorcars Fort Worth identify root causes quickly with OEM diagnostic tools to avoid unnecessary repairs.
• For covered repairs under warranty, work must be completed at a certified dealership to retain coverage and ensure proper parts and procedures.

What does it mean when the check engine light comes on in a 2025 Mercedes-Benz CLE?

• A check engine light signals that the vehicle’s onboard computer has detected a fault in emissions, ignition, fuel, or engine management systems.
• The light can indicate minor issues (loose gas cap, EVAP leak) or more serious faults (misfire, catalytic converter efficiency) that require prompt attention.
• Our dealership uses OEM-level scanners to read stored codes, interpret freeze-frame data, and recommend the correct repair path to avoid trial-and-error fixes.
• For warranty-covered faults, authorized service at Park Place Motorcars Fort Worth is required to maintain coverage and ensure repairs are done to factory standards.

How long does a check engine light service take?

• Time varies: a diagnostic scan and initial inspection typically take 30–90 minutes; repairs depend on the diagnosed issue and parts availability.
• Minor fixes (gas cap, sensor replacement) can often be completed the same day; complex repairs (catalytic converter, engine repairs) require longer intervals for parts and calibration.
• Park Place Motorcars Fort Worth prioritizes quick, accurate diagnostics and offers online scheduling via our Service Scheduler to minimize downtime.
• Warranty repairs must be completed at a certified dealership to protect your coverage and ensure correct procedures and parts are used.

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

• Start with the basics: check the gas cap is tightened—an EVAP leak from a loose cap is a common, simple cause.
• If the light remains, avoid long high-speed drives; record symptoms (power loss, unusual noises, flashing light) and schedule a diagnostic with us.
• Do not reset the light yourself without diagnosis; clearing codes can mask intermittent problems and void warranty coverage if repairs are later required.
• Book a timely inspection at Park Place Motorcars Fort Worth so factory-trained technicians can diagnose with OEM tools and preserve warranty eligibility for covered repairs.
