Description
Bosch Parking Assist Control Unit For Peugeot 407
Overview
High-quality Bosch control unit for the Parking Distance Control (PDC) system on Peugeot 407. This unit processes signals from the ultrasonic parking sensors and provides distance warnings to the driver via the vehicle’s buzzer and dashboard indicators. The listing is focused on professionals and experienced DIY mechanics who commonly search by OE and supplier numbers such as 0263004095, 6590L7 or 6590T5.
How It Works
The control unit receives input from multiple ultrasonic sensors mounted in the bumpers, filters and interprets echo signals, and determines obstacle distance. It then sends warnings to the vehicle’s HMI (audible beeper and visual indicators) and communicates vehicle status over the CAN network. Proper operation depends on intact sensors, secure connector contacts and correct software configuration for the vehicle.
Technical Information
- Manufacturer: Bosch
- Model: Peugeot 407
- Product Codes: 0263004095, 6590L7, 6590T5
- Additional Numbers: 9656174280, 9659350680
Recommended Replacement Procedure
- Before starting, disconnect the vehicle battery to avoid short circuits and protect electronic modules.
- Access the PDC control unit. On many vehicles it is located behind interior trim panels near the rear bumper or in the luggage compartment—remove the necessary trim or bumper covers following manufacturer guidance.
- Unplug all electrical connectors and release any mounting clips or screws holding the unit.
- Fit the replacement unit, secure fastenings and reconnect connectors ensuring clean, corrosion-free contacts.
- Reconnect the battery and perform system checks: verify sensor recognition, test audible and visual warnings, and clear any stored fault codes as required.
Installation Recommendations
- Always disconnect the battery before removal and installation.
- Handle connectors carefully; avoid pulling on wiring harnesses and protect pins from contamination.
- Clean and inspect mating surfaces and connector pins for corrosion. Use contact cleaner if needed.
- After installation, verify sensor wiring continuity and perform a functional test of the PDC system. If fault codes appear, address sensor or wiring issues first.
Most Common Failure Reasons
- Water ingress and corrosion in connectors or the housing—moisture is the most frequent cause of failure.
- Physical damage due to impacts or collisions that affect sensors, wiring or the control unit.
- Short circuits or electrical surges damaging internal electronics, often caused by faulty sensors or damaged wiring.
- Connector pin corrosion or poor grounding leading to intermittent faults or complete loss of function.
- Age-related degradation of seals and potting compounds allowing moisture penetration over time.
Practical Notes For Workshops And DIYers
Searches are often performed by OE or supplier numbers, so use the product codes listed above when checking fitment. The unit itself is an electronic control module rather than a wear item; proper installation and ensuring sensor/wiring integrity are critical for reliable operation. If the PDC system shows faults after fitting a new unit, inspect sensors and harnesses thoroughly before concluding the replacement unit is defective.
