Frequently Asked Questions

What is the first thing to check when the check engine light comes on in a 2016 Mercedes-Benz S-Class?

  • Start with simple visual checks: secure the gas cap and confirm the fuel filler is closed—an EVAP leak from a loose cap is a common trigger.
  • Scan for obvious symptoms: unusual noises, loss of power, smoke, or overheating. If the car runs roughly, avoid driving far.
  • Check dashboard gauges (oil, temperature) and ensure fluids are normal; low oil or overheating can cause immediate harm.
  • If the light is flashing, stop driving and contact us—flashing often signals an active misfire that can damage the catalytic converter.
  • Schedule a factory diagnostic with Park Place Motorcars Fort Worth online to protect warranty coverage and save on long-term repairs: /service/schedule-appointment-pmf.htm.

What is the most common reason for the check engine light on a 2016 Mercedes-Benz S-Class?

  • One of the most frequent causes is an EVAP system leak—often a loose or damaged gas cap that triggers an emissions code.
  • Other common faults include oxygen sensor failure, ignition misfires, and failing catalytic converter efficiency readings (which can be costly if ignored).
  • Environmental factors and aged wiring/connectors can also produce codes that need professional diagnosis with dealer tools.
  • Addressing the issue at Park Place Motorcars Fort Worth with factory diagnostics prevents escalation and typically costs less over time than repeated independent repairs.
  • Schedule a certified inspection to confirm root cause and preserve warranty eligibility: /service/schedule-appointment-pmf.htm.

2016 Mercedes-Benz S-Class Check Engine Light Flashing

A flashing check engine light on a 2016 Mercedes-Benz S-Class almost always signals an active misfire or severe engine condition that risks immediate damage, especially to the catalytic converter. Continued driving under a flashing condition increases exhaust temperatures and can warp or destroy the converter, leading to costly replacements. For safety and cost control, stop driving when safe, avoid hard acceleration, and contact Park Place Motorcars Fort Worth for towing and diagnostic priority. Our factory-trained technicians use dealer-level analyzers to identify misfires, ignition, and fuel system faults quickly. Because warranty-covered repairs must be done at a certified dealer, timely service here protects your coverage and reduces long-term expense.

2016 Mercedes-Benz S-Class Check Engine Light Reset

Resetting the check engine light on a 2016 Mercedes-Benz S-Class can be done with an OBD-II scanner, but clearing codes without repairing the underlying fault is only a temporary fix and can hide problems that cause further damage. Dealer-level resets often include follow-up readiness tests and software updates so the vehicle’s control modules perform correctly. At Park Place Motorcars Fort Worth we pair code clearing with comprehensive diagnostics, genuine OEM parts, and required reprogramming so your vehicle meets emissions and warranty requirements. Choosing dealership service often costs less over time because we prevent repeat failures, maintain proper module calibration, and ensure any warranty work is completed by certified technicians.

2016 Mercedes-Benz S-Class Check Engine Light Codes

Common codes on a 2016 Mercedes-Benz S-Class include P0300 (random/multiple misfire), P0420 (catalyst efficiency low), P0171 (system too lean), P0442 (EVAP small leak), and P0135 (oxygen sensor heater). Ignoring these codes can lead to poor fuel economy, failed emissions testing, and progressive engine or emissions-system damage—catalytic converter replacement can range into the thousands if left unchecked. Oxygen sensors and EVAP repairs are typically less costly but escalate if neglected. Park Place Motorcars Fort Worth provides dealer diagnostics that pinpoint the correct repair and use OEM parts to avoid repeat failures. Repairs covered under warranty must be performed here to preserve coverage and save you money long term.
