Descrizione
OEM part number 6904010. This is a genuine used BMW PDC control module (parking sensor ECU) for the E46 3 Series and E39 5 Series. Each unit is tested before listing and supplied in good used condition.
As the central controller of the parking distance warning system, this module provides power to and exchanges data with every ultrasonic sensor installed in the bumper. It measures the round-trip travel time of ultrasound pulses reflected from nearby objects to continuously compute obstacle proximity. The calculated distance is translated into a stepped audible warning — tones growing more rapid as clearance decreases — and, on models with a graphical display, the module drives the proximity visualisation shown in the instrument cluster or iDrive interface. System communication runs across the vehicle CAN bus.
Parking sensor system completely silent when reverse gear is selected or when the front sensors are activated, audible warning tones absent during close-proximity manoeuvring, a constant unwanted beeping when no obstacle is present, a PDC warning message or amber alert symbol appearing on the instrument cluster, or one or more sensor positions appearing unresponsive while the others function correctly.
The module is supplied in good used condition. Please confirm the OEM part number matches your exact vehicle configuration before purchasing — PDC control modules are vehicle-specific and multiple variants exist across the model range. Fitting by a qualified technician is strongly advised. On most applications, coding to the vehicle VIN via BMW ISTA is required following installation; a module that has not been coded may fail to activate or generate continuous stored fault codes. Returns are accepted within 14 days on parts returned unmodified.
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.
