Setup, Compatibility & Care
Installation should be performed by someone familiar with vehicle trim removal, as many E46 models require accessing the rear or front bumper mounting points. Always disconnect the negative battery terminal before handling electrical sensors to prevent short circuits.
Compatibility: This unit is specifically engineered for BMW E46 series vehicles and replaces OEM part numbers 66206911831, 66206989067, and 6989067.
Care Instructions: To maintain sensor performance, keep the sensor face free of thick mud, ice, or heavy road debris, as these can cause 'ghost' signals or system errors. Use a soft cloth and mild soap to clean the surface; avoid abrasive chemicals or pressure washing directly at the sensor interface.
