The most common reasons a 2013 Mercedes-Benz E63 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 2013 Mercedes-Benz E63 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 2013 Mercedes-Benz E63 AMG?

When faced with a check engine light on your 2013 Mercedes-Benz E63 AMG, it's essential to approach the diagnosis methodically. Start by checking the gas cap; a loose or damaged cap is a common and easily fixable issue that can trigger the light. Next, examine your dashboard for any additional warning indicators that might offer further insights into the problem. Utilizing an OBD-II scanner is a crucial step, as it allows you to retrieve error codes from the vehicle's computer, helping to identify the specific issue at hand. Additionally, inspect the condition of your spark plugs, as worn or faulty plugs can contribute to engine performance problems. Finally, ensure that all essential fluid levels—such as oil, coolant, and transmission fluid—are adequate, as low levels can lead to significant engine complications. By following these initial diagnostic steps, you can effectively narrow down the cause of the check engine light and take appropriate action to resolve the issue.

What are the common problems that could cause the check engine light to activate in a 2013 Mercedes-Benz E63 AMG?

When the check engine light illuminates in a 2013 Mercedes-Benz E63 AMG, it often signals underlying issues that require attention. One of the most frequent culprits is a faulty oxygen sensor, which can disrupt the air-fuel mixture and negatively impact engine performance. Another common issue is a loose gas cap; if the cap is not sealed properly, it can lead to fuel vapor leaks, reducing fuel efficiency and triggering the warning light. Additionally, problems with the catalytic converter, such as clogs or failures, can also activate the check engine light while potentially diminishing engine power. A malfunctioning mass airflow sensor is another concern, as it can miscalculate air intake, further affecting engine performance. Lastly, worn or faulty spark plugs can cause misfires and rough idling, contributing to the check engine light's activation. Addressing these issues promptly is crucial for maintaining the vehicle's performance and preventing more severe damage. For DIY enthusiasts, understanding these common problems can aid in troubleshooting and repairs, ensuring a smoother driving experience.

How urgent is it to address the check engine light in a 2013 Mercedes-Benz E63 AMG?

When the check engine light illuminates in your 2013 Mercedes-Benz E63 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 more severe mechanical failures. For DIY enthusiasts, it’s crucial to understand that while some minor issues may seem manageable, the underlying causes of the check engine light can often be complex and require specialized knowledge to diagnose accurately. Delaying action not only risks incurring higher repair costs down the line but also poses safety risks, as certain engine malfunctions can affect vehicle handling and emissions. Therefore, it is advisable to utilize an OBD-II scanner to retrieve diagnostic trouble codes, which can provide insight into the specific issues at hand. However, if the codes indicate a serious problem, seeking professional assistance is the best course of action to ensure the longevity and reliability of your vehicle.
