How much does it cost to fix a 2016 Mercedes-Benz E63 AMG S cruise control isn't working?

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.

In the event that a wheel speed sensor fails, the ABS, traction control system (TCS) and manufacturer specific stability control system lights will illuminate, informing the driver that the systems are disabled. The vehicle will be more prone to tire slip, and normal driving patterns may need to be adjusted to correct for the loss of computer control. On older vehicle's, the speedometer can be affected, causing illumination of the check engine light as well.

The cruise control switch can cause complete failure of the cruise control feature, but in a lucky scenario only partial functionality will be lost. This means that the cruise control may come on, but that it will not increase in speed automatically, or the cancel button does not work leading the driver to cancel cruise control with the foot brake. In some vehicles, the cruise control light may illuminate, or a warning message may be displayed due to lack of functionality.

What are the steps to diagnose the cruise control issue in a 2016 Mercedes-Benz E63 AMG S?

When diagnosing a cruise control issue in a 2016 Mercedes-Benz E63 AMG S, it's crucial to follow a methodical diagnostic approach that prioritizes simpler checks before delving into more complex solutions. Begin by examining the cruise control fuse, as a blown fuse is a common and easily rectifiable problem that can disrupt the system's operation. Next, assess the functionality of the cruise control buttons located on the steering wheel; malfunctioning buttons can prevent proper engagement of the system. Utilizing a diagnostic scanner to retrieve error codes from the vehicle's onboard computer can provide critical insights into any specific issues affecting the cruise control. It's also important to check the speed sensors, as they are integral to the cruise control's performance. A thorough inspection of the wiring and connections for signs of damage or corrosion is essential, as these factors can significantly impair functionality. Lastly, testing the cruise control module will help confirm whether it is operating correctly. By systematically addressing these areas, you can effectively diagnose and resolve cruise control issues, ensuring your Mercedes-Benz E63 AMG S operates smoothly and reliably on the road.

What are the common problems that could cause the cruise control to stop working in a 2016 Mercedes-Benz E63 AMG S?

When the cruise control in your 2016 Mercedes-Benz E63 AMG S ceases to function, it can be frustrating, but understanding the common problems can help you diagnose the issue effectively. One of the primary culprits is a faulty brake light switch, which may fail to signal the system when the brake pedal is pressed, thereby preventing cruise control from engaging. Additionally, issues with the speed sensor can lead to incorrect speed readings, causing the system to malfunction or disengage unexpectedly. Another potential problem is a malfunctioning throttle actuator, which is crucial for maintaining a consistent speed; if it fails, the cruise control may struggle to operate correctly. Electrical problems, such as blown fuses or wiring issues, can also disrupt the cruise control system, as can vacuum leaks in the engine that affect its operation. By systematically checking these components, you can identify and address the root cause of your cruise control issues, allowing you to restore functionality and enjoy a smoother driving experience.

How urgent is it to address the non-functioning cruise control in a 2016 Mercedes-Benz E63 AMG S?

Addressing the non-functioning cruise control in your 2016 Mercedes-Benz E63 AMG S should not be overlooked, even if it may seem like a minor inconvenience. While the absence of this feature does not pose an immediate safety risk, it can lead to increased driver fatigue during long journeys and may negatively impact fuel efficiency. Ignoring the problem could also result in more significant underlying issues that may require costly repairs down the line. For those inclined to tackle this issue themselves, it is crucial to start with a thorough inspection of the cruise control system, including checking the fuses, wiring, and any potential error codes that may be present. If the problem persists, consulting a qualified mechanic or authorized service center is advisable to ensure a proper diagnosis and resolution. By addressing the cruise control malfunction promptly, you can enhance your driving experience and prevent further complications, making it a worthwhile DIY project.
