BOSCH Parking Assist Control Unit For Peugeot 407
Reliable replacement ECU for the Parking Distance Control (PDC) system on Peugeot 407 vehicles. This BOSCH control unit processes ultrasonic sensor signals, manages audible and visual alerts and ensures correct parking assistance behavior. Ideal for professional workshops and skilled DIY mechanics who need a direct-fit electronic module referenced under common OEM numbers (see Technical Information). The unit helps restore proper PDC function after sensor faults, water damage or electrical failures and can significantly reduce diagnostic time when the correct product code is known.
Technical Information
- Manufacturer: Bosch
- Model: Peugeot 407
- Product Codes: 0263004095, 263004095

Function
The ECU Controls The Parking Assist System By Receiving Inputs From Ultrasonic Sensors, Evaluating Obstacle Distance And Triggering Acoustic And Visual Warnings. It Monitors Sensor Health And Communicates With The Vehicle Network To Display Information On The Instrument Panel Or Head Unit Where Applicable.
Applications And Compatibility
Primarily Intended For Peugeot 407 Vehicles. The Unit Is Also Listed Under Several Stellantis References And May Be Interchanged Where The Same OEM Part Numbers Are Used. Always Match The Product Codes Above With The Defective Unit To Ensure Correct Fitment.
How To Replace
General Replacement Steps (Vehicle-Specific Procedure May Vary):
- Disconnect The Negative Battery Terminal Before Any Work On The Electrical System.
- Access The Control Unit Location Per Vehicle Repair Manual (Trim Panels Or Luggage Compartment Covering May Need Removal).
- Unplug All Connectors Carefully, Unlock Any Retaining Clips And Remove Mounting Fasteners.
- Install The New Unit, Secure Fasteners And Reconnect Connectors Firmly.
- Restore Battery Power And Use A Diagnostic Tool To Clear Fault Codes, Run Sensor Tests And Verify Proper Function Of The PDC System.
Recommended Installation
Perform Installation In A Clean, Dry Environment. Observe ESD Precautions When Handling Electronic Modules. Use A Diagnostic Scanner To Verify Communication With The New Unit, Clear Historic Faults And Run The PDC Self-Test Sequence. If The System Shows Faults After Replacement, Inspect Sensor Wiring And Grounds Before Replacing Additional Modules.
Why This Part Commonly Fails
PDC Control Units Often Fail Due To Water Ingress Or Corrosion Of Connectors, Physical Impact From Rear Bumper Damage, Or Electrical Disturbances Such As Short Circuits And Voltage Spikes. Other Common Causes Include Faulty Ultrasonic Sensors That Place Excessive Load On The Module And Long-Term Degradation From Environmental Exposure.
Notes For Professionals
This Control Unit Is A Critical Electronic Component. While Many Replacements Are Plug-And-Play When Matching The Same Hardware And Software Versions, Some Vehicles May Require Diagnostic Initialization Or Software Matching After Installation. For Reliable Results, Use Standard PSA/Manufacturer Diagnostic Procedures To Confirm System Integrity.
