How much does it cost to fix a 2017 BMW 650i Gran Coupe 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.

What steps should I take to diagnose the cruise control issue in my 2017 BMW 650i Gran Coupe?

To effectively diagnose the cruise control issue in your 2017 BMW 650i Gran Coupe, start with the simplest solutions before progressing to more complex diagnostics. Begin by checking the cruise control fuse, as a blown fuse can easily disrupt functionality. Next, inspect the cruise control buttons on the steering wheel for any signs of damage or wear that could hinder their operation. If these initial checks do not reveal the problem, use an OBD-II scanner to identify any error codes that may provide insight into the issue. Following this, verify the functionality of the speed sensors, as they are essential for the cruise control system to operate correctly. Additionally, examine the wiring connections associated with the cruise control system for any loose or damaged wires. If all else fails, test the cruise control module to ensure it is properly sending and receiving signals. Should you still be unable to pinpoint the issue, it may be wise to consult a professional mechanic or an authorized BMW service center for a comprehensive diagnosis and repair. By following this structured approach, you can systematically identify and address the cruise control problem in your vehicle.

What are the common problems that could cause the cruise control to stop working in a 2017 BMW 650i Gran Coupe?

When troubleshooting the cruise control system in a 2017 BMW 650i Gran Coupe, it's essential to understand the common problems that may lead to its malfunction. One of the primary culprits is a faulty speed sensor, which can disrupt the system's ability to accurately gauge the vehicle's speed, preventing it from engaging or maintaining the desired speed. Additionally, issues with the brake light switch can pose significant challenges; since the cruise control is designed to disengage when the brake pedal is pressed, a malfunctioning switch may fail to signal this action, resulting in the cruise control ceasing to function. Another potential issue is a malfunctioning throttle actuator, which is responsible for controlling the engine's throttle opening and can hinder the system's ability to maintain a constant speed. Electrical problems, such as blown fuses or wiring issues, can also impede the cruise control's operation, as can vacuum leaks in the engine that disrupt the necessary vacuum pressure for the system to work correctly. By identifying and addressing these common problems, DIY enthusiasts can effectively restore the cruise control functionality in their BMW.

How urgent is it to address the non-functioning cruise control in a 2017 BMW 650i Gran Coupe?

When it comes to the non-functioning cruise control in a 2017 BMW 650i Gran Coupe, understanding the urgency of the situation is crucial for any DIY enthusiast. While this issue may not pose an immediate safety risk like malfunctioning brakes or steering, it is still important to address it promptly. A functioning cruise control system enhances driving comfort, particularly on long trips, by allowing the driver to maintain a steady speed, which can also contribute to better fuel efficiency. Ignoring this problem could lead to increased driver fatigue and inconvenience during highway driving, where cruise control is most beneficial. Moreover, delaying repairs might allow underlying issues to worsen, potentially leading to more significant and costly repairs down the line. Therefore, while the urgency may not be as high as with other critical vehicle components, taking timely action to fix the cruise control will ensure the overall performance and convenience of your BMW remain intact.
