Frequently Asked Questions

What is the most common reason for check engine light on a 2026 Mercedes-Benz CLE?

• Common causes include ignition misfires, oxygen sensor or catalytic converter issues, and evaporative emissions (EVAP) leaks.
• Misfires can lead to increased emissions and catalytic converter damage — addressing them early avoids larger repair costs.
• Our dealership often costs less than independent shops when factoring diagnostics credit, parts warranties, and long-term reliability offered by factory-trained technicians.
• Repairs covered under warranty must be done at a certified dealership to preserve coverage and ensure genuine parts and software updates.

What does it mean when the check engine light comes on in a 2026 Mercedes-Benz CLE?

• The light indicates the vehicle’s onboard diagnostics has detected a system outside normal parameters — anything from minor sensor drift to engine misfire.
• It does not always mean a major failure, but it signals that a diagnostic scan is needed to identify the trouble code(s).
• Getting service at our dealership ensures accurate diagnosis with Mercedes-Benz diagnostic tools and software calibrations that independent shops may not have.
• Timely dealer diagnosis can provide immediate savings by avoiding compounded damage and preserving warranty eligibility for covered repairs.

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

• Check for obvious issues first: a loose or missing gas cap can trigger an EVAP code and is an easy fix.
• If no simple fix is found, schedule a diagnostic so our technicians can read the stored trouble codes and live data using Mercedes diagnostic tools.
• If your vehicle is under warranty, remember any warranty-covered repair must be completed at a certified dealership to retain coverage.
• Bringing the car to Park Place Motorcars Fort Worth often reduces both immediate and long-term costs thanks to accurate diagnosis, proper repairs and parts backed by warranty.
