BMW i8 2014-2020 Emissions & Sensors Specifications

The BMW i8 from 2014 to 2020 is equipped with advanced emissions sensors, including oxygen sensors and exhaust gas temperature sensors. These sensors are designed to monitor and regulate emissions, ensuring optimal performance and compliance with emissions standards. The oxygen sensors are lambda probes that measure oxygen levels in the exhaust gases, while the exhaust gas temperature sensors monitor temperatures to prevent overheating. These sensors are compatible with the i8's 1.5L TwinPower Turbo engine and hybrid powertrain system.

Regular maintenance for the emissions sensors in the BMW i8 includes periodic inspections of the oxygen sensors and exhaust gas temperature sensors. It is recommended to replace the oxygen sensors every 60,000 to 80,000 miles or as specified in the service manual. Additionally, ensuring proper engine tuning and avoiding contamination from fuel or oil leaks can help maintain sensor accuracy. Always use BMW-approved replacement parts and consult a certified technician for any service.

To replace an emissions sensor in the BMW i8, start by locating the sensor, which is typically found in the exhaust system near the catalytic converter. Disconnect the battery and allow the system to cool. Use a wrench to remove the sensor's mounting nut, then carefully pull the sensor out of its housing. Install the new sensor by reversing the steps, ensuring it is securely tightened. Reconnect the battery and use a scan tool to clear any fault codes. Always refer to the service manual for specific instructions.

Common issues with emissions sensors in the BMW i8 include faulty readings, contamination, or electrical connectivity problems. Use a scan tool to check for fault codes such as P0130 (O2 sensor circuit malfunction) or P0036 (exhaust gas temperature sensor circuit). Inspect the sensors for physical damage or soot buildup. Clean or replace the sensors as needed, and check wiring connections for corrosion or damage. If issues persist, consult a certified BMW technician for further diagnosis.

To optimize the performance of the emissions sensors in the BMW i8, ensure proper engine tuning and regular maintenance. Avoid aggressive driving that may cause excessive heat buildup in the exhaust system. Use high-quality fuel to prevent contamination of the sensors. Regularly update the vehicle's software to ensure the emissions control system is functioning optimally. Additionally, consider using BMW-approved sensor cleaners or replacements to maintain sensor accuracy and reliability.
