Description
OEM part number 6982403. This is a genuine used BMW PDC control module (parking sensor ECU) for the E90 3 Series saloon and E92 3 Series Coupé. Units are tested before listing and supplied in good used condition.
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.
Failure of this unit is typically indicated by complete silence from the parking sensors when reverse gear is engaged, the absence of alert tones during tight manoeuvring, an uninterrupted beeping tone sounding with no obstacle detected, a PDC fault or warning lamp appearing in the instrument cluster, or individual sensor positions becoming unresponsive while adjacent sensors remain active.
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.
