2026 BMW 530i Cruise Control Not Working

Some BMW 530i owners report experiencing issues related to a malfunctioning Mass Air Flow (MAF) sensor, including rough idle and power loss. Symptoms of a bad MAF sensor can manifest as loss of power, slow acceleration, engine hesitation, erratic idling, misfires, poor exhaust emissions, and black smoke from the tailpipe. A dirty or faulty MAF sensor may lead to an incorrect air-to-fuel ratio, contributing to these performance problems. Additionally, rough idling can also be linked to a malfunctioning Idle Control Valve (ICV), which regulates idle speed. Improper installation of a MAF sensor can result in false readings, causing the engine computer to deliver incorrect fuel amounts and further exacerbating idle issues. Even after replacing the MAF sensor, some owners may still experience rough idle due to other factors such as low fuel pressure, a dirty throttle body, vacuum leaks, or incomplete MAF learning procedures. Proper diagnosis and maintenance are essential for restoring the vehicle's performance and addressing these concerns.

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.
