How much does it cost to fix a 2014 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 2014 Mercedes-Benz E63 AMG S?

To effectively diagnose the cruise control issue in your 2014 Mercedes-Benz E63 AMG S, start with the simplest solutions. Begin by checking the fuses and relays associated with the cruise control system, as a blown fuse can often be the culprit behind malfunctioning features. Next, inspect the cruise control switch located on the steering wheel to ensure it is operational; a faulty switch can prevent the system from engaging. If these initial checks do not reveal the problem, examine the cruise control module for any visible damage or corrosion, which could impair its functionality. Additionally, testing the cruise control sensors is crucial, as they must accurately relay information to the module for the system to work correctly. Finally, utilize an onboard diagnostic scanner to check for any error codes that may indicate specific issues within the cruise control system. If these steps do not resolve the problem, it may be time to consult a professional mechanic for a more thorough diagnosis. By following this structured approach, you can efficiently identify and address the cruise control issue in your vehicle.

What are the common problems that could cause the cruise control to stop working in a 2014 Mercedes-Benz E63 AMG S?

When the cruise control in your 2014 Mercedes-Benz E63 AMG S ceases to function, several common issues may be at play. One of the first things to check is the brake pedal switch, as a malfunctioning switch can interrupt the cruise control system. Additionally, inspect the fuses related to the cruise control; a blown fuse can prevent the system from operating altogether. If the cruise control exhibits intermittent functionality, it may be due to faulty components or sensors that are essential for its operation. Pay attention to the throttle body as well, as issues here can also impact cruise control performance. Lastly, ensure that your brake lights are functioning correctly, as defective brake lights can signal to the system that the brakes are engaged, thereby disabling cruise control. By systematically checking these components, you can potentially identify and resolve the issue without needing to visit a mechanic.

How urgent is it to address the non-functioning cruise control in a 2014 Mercedes-Benz E63 AMG S?

When it comes to the non-functioning cruise control in a 2014 Mercedes-Benz E63 AMG S, addressing the issue should be a priority, even if it may not seem urgent at first glance. While the absence of cruise control does not directly compromise the vehicle's safety or drivability, it can significantly detract from the overall driving experience, especially during long trips where maintaining a consistent speed is beneficial for both comfort and fuel efficiency. Ignoring this issue could lead to increased driver fatigue and frustration, particularly on highways where cruise control is most commonly utilized. Moreover, delaying repairs may allow underlying electronic problems to escalate, potentially resulting in more complex and costly repairs down the line. Therefore, while it may not be an immediate emergency, taking prompt action to restore the cruise control functionality is advisable to ensure a more enjoyable and efficient driving experience.
