Frequently Asked Questions

What is the most common reason for check engine light on a 2025 Mercedes-Benz Maybach GLS GLS 600?

• Common causes include misfires, failing oxygen sensors, mass air flow issues, or exhaust catalyst efficiency codes.
• For a twin-turbo V8, ignition or fuel delivery irregularities can show first; addressing them quickly prevents turbo and catalytic damage.
• Our factory-trained technicians use Mercedes-Benz diagnostic tools to identify root causes and recommend the correct repair plan.
• Repairs covered under warranty must be completed at a certified dealership to maintain coverage and long-term value.

How long does a check engine light service take?

• Typical diagnostic time ranges from 30 minutes to a few hours depending on code complexity and road-test needs.
• Simple sensor replacements can often be completed the same day; complex repairs require additional inspection or parts and may take longer.
• At Park Place Motorcars Fort Worth we prioritize accurate diagnosis over speed to avoid repeat visits and provide immediate and long-term savings.
• Schedule an appointment online at our service scheduler to minimize wait time: Service Scheduler.

What does it mean when the check engine light comes on in a 2025 Mercedes-Benz Maybach GLS GLS 600?

• The light signals the vehicle’s onboard computer has detected a fault — anything from an emissions sensor to an engine misfire.
• Some conditions are minor; some could lead to reduced fuel economy, increased emissions, or engine/turbo damage if ignored.
• Bring your vehicle to Park Place Motorcars Fort Worth for a full diagnostic with factory-level tools to determine severity and preserve warranty eligibility.
• Our certified technicians ensure repairs are performed to Mercedes-Benz standards, often delivering lower total ownership costs than independent shops.

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

• Confirm obvious items first: tight gas cap and recent fuel type — the Maybach GLS requires premium unleaded fuel.
• If the gas cap is secure and the light remains, avoid prolonged driving and have a diagnostic scan performed to read stored codes.
• Do not reset the light at home; a temporary reset can mask an underlying issue and jeopardize warranty coverage.
