Frequently Asked Questions

What does it mean when the check engine light comes on in a 2016 Mercedes-Benz CLS-Class?

It indicates that the vehicle’s onboard diagnostics (OBD-II) system has stored a fault code — anything from an emissions sensor to an ignition misfire.
At Park Place Motorcars Dallas, our factory-trained technicians use Mercedes-Benz diagnostic tools to identify the exact code and recommend OEM repairs that protect long-term value.
Choosing dealership service often costs less than independent shops when you factor in accuracy, genuine parts, and reduced rework — delivering immediate and long-term savings.
We offer service financing so you can get repairs now and pay later, plus seasonal service specials to reduce out-of-pocket expense.
Remember: any repair covered under warranty must be performed at a certified dealership to maintain coverage and vehicle integrity.

How long does a check engine light service take?

Diagnostic scans and inspection typically take 30–90 minutes depending on symptoms and whether a road test or live-data capture is required.

Check Engine Light Flashing

A flashing check engine light on a 2016 Mercedes-Benz CLS-Class means the engine is misfiring or a fault is creating conditions that can cause immediate damage. In Dallas, Park Place Motorcars Dallas recommends pulling safely to the side and scheduling a prompt inspection rather than continuing to drive. Ignoring a flashing indicator can lead to severe consequences — burned catalytic converters, increased fuel consumption, and potential engine damage that dramatically raises repair costs. Our technicians use Mercedes-Benz factory diagnostic equipment to capture real-time data, perform controlled road tests when needed, and isolate root causes quickly. We back repairs with OEM parts and clear estimates so you understand immediate costs and long-term savings. Take advantage of available service specials and our service financing options to manage expense. To protect performance and avoid secondary damage, schedule service at Park Place Motorcars Dallas today — our certified team will prioritize safety and lasting value.

2016 Mercedes-Benz CLS-Class Check Engine Light Reset

Resetting the check engine light on a 2016 Mercedes-Benz CLS-Class is a simple step after repairs, but a reset alone does not address underlying faults. At Park Place Motorcars Dallas we explain why a true resolution requires a calibrated diagnostic, OEM replacement parts when needed, and confirmation that the fault is cleared from the vehicle’s control modules. Dealer-performed resets paired with verified repairs protect your warranty and reduce the chance of recurring issues that independent shops might miss. Our transparent process includes written estimates, technician notes, and a post-repair verification drive. For added value we offer rotating service specials and service financing so you can complete necessary work without delay. When you want confident, warranty-safe service from certified Mercedes-Benz technicians, schedule service online and trust Park Place Motorcars Dallas for accuracy and peace of mind.

2016 Mercedes-Benz CLS-Class Check Engine Light Codes

Common OBD-II codes on a 2016 Mercedes-Benz CLS-Class include misfire codes (P0300–P0312), oxygen sensor faults (P0130–P0167), catalytic efficiency codes (P0420), and EVAP system leaks (P0440–P0457). Left unresolved, these codes can escalate repair costs: persistent misfires can destroy a catalytic converter (replacement can be costly), oxygen sensor faults reduce fuel economy and emissions compliance, and EVAP leaks may lead to failed inspections. At Park Place Motorcars Dallas we diagnose codes using Mercedes-Benz factory tools, explain the likely consequences of delayed repair, and provide honest cost comparisons demonstrating immediate and lifetime savings when you choose dealership service. Certified technicians, OEM parts, documented repairs, and available service specials combine to keep your CLS-Class performing like new.
