The most common reasons a 2008 BMW 528xi cruise control isn't working are failed control module, sensor or switch issues, or throttle actuation problems.

Sensor: A faulty sensor can lead to incorrect readings, causing issues with engine performance or triggering warning lights on the dashboard.
Control Module: A faulty control module can result in erratic vehicle behavior or failure of various electronic systems due to improper signal processing.
Throttle: A faulty throttle body or a defective accelerator pedal position sensor may be causing inconsistent acceleration and poor engine response.

How much does it cost to fix a 2008 BMW 528xi 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.

How urgent is it to address the non-functioning cruise control in a 2008 BMW 528xi?

Addressing the non-functioning cruise control in a 2008 BMW 528xi should not be overlooked, as it can lead to significant safety risks and potential vehicle damage if neglected. While it may seem like a minor inconvenience, a malfunctioning cruise control system can indicate deeper electrical issues that, if left unaddressed, could escalate into more serious problems affecting the vehicle's overall performance. Moreover, the absence of this feature can increase driver fatigue during long trips, compromising focus and safety on the road. Timely intervention not only ensures a smoother driving experience but also helps maintain fuel efficiency, making it a practical concern for any driver. Therefore, it is advisable to consult a qualified mechanic promptly to diagnose and resolve any underlying issues, ensuring both the safety and functionality of your vehicle.

Mitsubishi Diamante cruise control malfunction after drive line obstruction removal

Some Mitsubishi Diamante owners report experiencing cruise control malfunctions after removing a drive line obstruction, often linked to issues with the control module, sensor, or switch. These problems may stem from failed components that prevent the cruise control system from engaging or holding speed, despite power being available to the dash and fuse. Additionally, throttle actuation issues, such as a faulty throttle position sensor, can lead to the engine's computer overcompensating with fuel, which may result in black exhaust from the tailpipe. Owners are advised to thoroughly troubleshoot the cruise control system and inspect key components like the control module, sensor, and throttle to identify any damage or malfunction caused during the obstruction removal process.

Acura TL cruise control will not engage after multiple button presses

Some Acura TL owners report experiencing difficulties with their cruise control not engaging, even after multiple button presses. This issue may stem from a faulty cruise control switch on the steering wheel, which can malfunction and prevent proper engagement. Additionally, problems with the control module, sensors, or switches are common culprits behind cruise control failures. Throttle sensor failures can also contribute to these malfunctions. Some owners find that a bad clock spring, located behind the steering wheel, affects the functionality of the cruise control buttons. Furthermore, issues related to the cruise system components, such as the brake switch, cruise servo, or wiring, may also be involved. To diagnose the problem, some owners recommend using a scan tool to identify any fault codes that could be disabling the cruise control system. It is also advisable to check for blown fuses related to the cruise control system, as these can disrupt power supply to essential components. If the cruise control remains unresponsive, it is important to have the necessary components checked or replaced to effectively resolve the issue.
