The most common reasons a 2016 Mercedes-Benz GLE63 AMG has a check engine light are an emissions system component, a sensor, or a catalytic converter.
  • Emissions System: A faulty emissions system component, such as an oxygen sensor or EGR valve, can lead to increased emissions and trigger the check engine light.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 2016 Mercedes-Benz GLE63 AMG has a check engine light?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

A faulty oxygen sensor is one of the most common causes of a check engine light. Symptoms may include a decrease in fuel mileage, hesitation or misfiring from the engine, rough idling or even stalling. A faulty sensor may cause the vehicle to fail an emissions test.

Any time there is an emissions fault the check engine light will be displayed. The purpose of the check engine light is to inform the driver that an emission related fault has been found, and that there are on-board diagnostic (OBD) trouble codes stored in the powertrain or engine control module. Additionally, since the emissions systems are so intertwined into engine control and transmission control systems, symptoms may include nearly any sort of drivability concerns. This may include harsh shifting, failure to shift, hesitation on acceleration, jerking, engine failure to start or run, loss of power, or any number of other drivability issues.

Due to the nature of electrical systems on modern vehicles, the range of problems these can cause are nearly limitless. However, there is a way to categorize them in two ways. Permanent and intermittent problems. Permanent problems appear and remain. This may be the vehicle will not start, the radio does not work, or the door chime will not turn off among many, many others. These problems are more straight-forward to diagnose since they present themselves at all time. This means there will always be a fault to find. Intermittent electrical problems, however, can be difficult or impossible to locate, since they appear then disappear without warning. The best case scenario for an intermittent issue is when replicating the problem is easily accomplished and understood. This allows a technician to make an issue semi-permanent, allowing them to find the fault. Other issues that come and go without warning and cannot be replicated on demand must occur when the technician is servicing the vehicle, otherwise there is no problem to correct. It is most important to understand that electrical system faults always require inspection, and can include the vehicle working in any manner, or not working at all.

Like we noted in the last section, general diagnosis symptoms are the most vague of the bunch. There are several diagnostic spectrums, electrical diagnosis, drivability diagnostics, engine diagnostics, transmission diagnostics, and the list could continue for about 5 or 10 more spectrums of diagnostics. The most important take-away here, is that general diagnostics are diagnostics that have no other spectrum in which they fit, or the problem is unknown. This means that any vehicle left outside of a repair facility with the keys and an authorization to perform diagnosis will be diagnosed under the general diagnosis spectrum.

When the Check Engine Light comes on, you may experience engine performance issues such as poor acceleration, rough idling, or an engine that won't start. In some cases, no abnormal symptoms will be experienced. Other systems like the transmission or ABS can cause the Check Engine Light to illuminate and lights for those systems can come on at the same time. Similar lights may say "Check Engine Soon", "Malfunction Indicator Light" or just "Check". In rare case the engine can overheat.

What are the initial diagnostic steps to take for a check engine light on a 2016 Mercedes-Benz GLE63 AMG?

When faced with a check engine light on your 2016 Mercedes-Benz GLE63 AMG, the first step is to check for a loose gas cap, as this is a common and easily fixable issue that can trigger the warning light. Next, inspect your dashboard gauges for any additional warning lights or unusual readings that may offer further insight into the problem. Utilizing an OBD-II scanner is crucial; connect it to the vehicle's diagnostic port to retrieve any error codes stored in the system. Once you have the codes, interpret them to identify the specific issue causing the check engine light. Additionally, ensure that essential fluid levels—such as oil, coolant, and transmission fluid—are adequate, as low levels can also lead to warning lights. A visual inspection of wiring and connections under the hood is important to check for any signs of damage or corrosion that could be affecting vehicle performance. Finally, consult your owner's manual for specific guidance related to the check engine light, as it may provide tailored recommendations for your model. By following these steps, you can effectively diagnose the issue and determine the best course of action for your vehicle.

What are the common problems that could cause the check engine light to activate in a 2016 Mercedes-Benz GLE63 AMG?

When the check engine light comes on in a 2016 Mercedes-Benz GLE63 AMG, it can indicate several common issues that DIY enthusiasts should be aware of. A faulty oxygen sensor is often a primary suspect, as it can significantly impact fuel efficiency and emissions. Another simple yet frequent cause is a loose gas cap; ensuring it is tightly secured can sometimes resolve the warning light. Additionally, problems with the catalytic converter, such as inefficiency or failure, can trigger the light, as can worn spark plugs that affect engine performance. A malfunctioning mass airflow sensor can disrupt the air-fuel mixture, leading to activation of the check engine light, while ignition coil issues may result in misfiring and rough idling. It’s essential to address these problems quickly to avoid further damage and maintain the vehicle's performance. For those who prefer a DIY approach, checking these components can be a good starting point, but consulting a qualified mechanic for a comprehensive diagnosis is recommended if the light persists.

How urgent is it to address the check engine light in a 2016 Mercedes-Benz GLE63 AMG?

When the check engine light illuminates in your 2016 Mercedes-Benz GLE63 AMG, it signals a potential issue that requires immediate attention. Ignoring this warning can lead to a cascade of problems, including reduced fuel efficiency and compromised engine performance, which may escalate into costly repairs. The urgency of addressing the check engine light cannot be overstated, as it often indicates underlying issues within the engine or emissions system that could pose safety risks. For those inclined to take a DIY approach, utilizing the vehicle's onboard diagnostics system can be a valuable first step. This system can help identify the specific trouble codes associated with the check engine light, allowing you to research and understand the potential causes. However, while some minor issues may be manageable at home, it is crucial to recognize when professional expertise is necessary to prevent further damage and ensure the longevity of your vehicle. Taking prompt action not only safeguards your investment but also enhances your driving experience by maintaining optimal performance.
