大众奥迪泊车雷达传感器 4B0919275B 电眼探头 原厂替换

When your vehicle reverses or moves in reverse and the parking radar system reports false positives, continuous chirping, no response, or detection range substantially reduced, this usually indicates aging or damaged piezoelectric ceramics or circuitry in the original sensors, leading to inaccurate ultrasonic transmission/ reception. The part is an OEM replacement, OEM number 4B0919275B; fits VW and Audi models including Passat, Magotan, A4, A6, etc. Installation: disconnect battery negative first; ensure sensor color matches bumper mounting holes; after installation, calibrate with a diagnostic tool to ensure all sensors operate without false alarms.
