Description
OEM part number 4104215. This is a genuine used BMW PDC control module (parking sensor ECU) for the E53 X5. Units are tested and confirmed functional before listing.
The PDC control module serves as the central processing unit for the parking distance warning system. It energises and interrogates each ultrasonic sensor fitted in the front and rear bumper, measuring the time of flight of reflected sound pulses to derive the distance between the vehicle and nearby obstacles. That distance data is translated into an escalating sequence of audible alert tones — increasing in frequency as the gap closes — and, where a visual display is fitted, the module feeds proximity information to the instrument cluster or iDrive screen. All communication with the body control module and further vehicle systems takes place over the CAN bus.
Signs that this module has failed include the parking distance system producing no sound when reverse gear is engaged or front sensors are switched on, missing alert tones during close manoeuvring, an unsolicited continuous beep, a PDC warning or fault indicator lit in the cluster, or isolated sensor positions becoming unresponsive while the rest of the system continues to function.
This module is supplied in good used condition. Always verify the OEM part number against your exact vehicle and specification before ordering — PDC modules are VIN-specific on most applications. Professional installation is recommended. Coding to the vehicle VIN using BMW ISTA diagnostic software is required after fitting on the majority of applications; without coding the system may not activate or may log persistent fault codes. 14-day returns are accepted on unmodified parts.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
