The Oxygen Sensor, OEM part number 7544655, is a critical component located in the vehicle's exhaust system, typically situated before and/or after the catalytic converter. Its primary function is to monitor the oxygen levels in the exhaust gases, enabling the Engine Control Unit (ECU) to adjust the air-fuel mixture for optimal combustion. This ensures efficient engine performance and reduced emissions. Common issues requiring replacement include faulty readings due to wear or damage, leading to poor fuel economy or increased emissions. Compatible with various BMW models such as the 525i, 525xi, 530i, 530xi (2006-2007), 528xi (2008), and 528i xDrive (2009-2010), this genuine OEM part guarantees reliability.
