This part cross-references BMW OE numbers 7502444 and 13547502444 for the same application.

Common Replacement Issues

• Unstable idle caused by throttle body wear or sensor failure.
• Throttle response problems from an aging electronic throttle assembly.
• Airflow control faults related to internal contamination or corrosion.
• Driveability concerns tied to a failing idle air control motor.

Installation Notes

Verify connector shape, pin count, inlet and outlet dimensions, and vehicle application before installation. Mounting hardware is not included, and no gasket or seal is included beyond the listed O-ring. Confirm the intake tract is clean and inspect related electrical connections before fitting Nissens 955113.
