Frequently Asked Questions

How long does a check engine light service take?

• Most diagnostic appointments at Park Place Motorcars Fort Worth begin with a full computer scan and visual inspection; typical diagnostics take 30–90 minutes depending on codes and conditions.
• If the issue is straightforward (sensor or minor component), repairs can often be completed the same day; complex repairs that require parts may take longer.
• Because we use factory diagnostic tools and factory-trained technicians, we often troubleshoot faster and more accurately than independent shops — which can translate to immediate and long-term savings.
• Repairs covered under warranty must be performed at a certified dealership to maintain warranty coverage and ensure reimbursements and OEM-quality parts.

What does it mean when the check engine light comes on in a 2013 Mercedes-Benz CLS-Class?

• It means the vehicle’s onboard diagnostics have detected an emissions, engine, or drivetrain fault; codes are stored in the ECU that point technicians to the subsystem.
• Common causes include misfires, catalytic converter efficiency issues, fuel trim problems, and evaporative system leaks — each carries different urgency and risk.
• Immediate scanning at a certified dealership gives an accurate description of the fault and preserves warranty rights when repairs are needed.
• Choosing Park Place Motorcars Fort Worth provides access to OEM parts and factory-trained technicians, often reducing total ownership cost versus repeated fixes at independent shops.

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

• Start with basics: ensure the gas cap is properly tightened; a loose or damaged cap frequently triggers EVAP codes.
• Check for obvious issues such as low oil, severe overheating, or unusual noises—these may indicate urgent conditions requiring a tow.
• Schedule a diagnostic scan as soon as possible so trained technicians can read stored codes and evaluate severity before further damage occurs.
• If the fault is covered by warranty, repairs must be completed at a certified dealership to maintain coverage and ensure the correct OEM components are used.
