Description
BOSCH brake booster for Stellantis vehicles
From a vehicle with 33,000 km mileage
Part description
The used BOSCH brake system part is listed as a Citroën Peugeot ABS ESP unit under numbers 0265956353 and 9812786180. The documentation also lists number 1654078580. One advantage is the documented mileage of the donor vehicle: 33,000 km. However, this alone does not replace checking the condition and operation of the used part.
The original description identifies the component as a brake booster, while the name and category place it among ABS ESP modules. Before selecting it, compare the markings and design with the old part. A match with the vehicle model alone is not sufficient grounds for substitution. This used part may be an economically sensible repair solution if it matches the required version and the fault in the original component has been correctly identified.

Product codes
Product codes: 0265956353, 9812786180, 1654078580.
The numbers are used to identify the listing and compare it with the markings on the original component. The documentation does not confirm that all the listed numbers are interchangeable for every vehicle version.
Installation recommendations
The following general procedure applies to replacing a brake system part. Due to the differing designations in the documentation, it is not possible to safely determine the exact component type or specific installation procedure. The exact steps depend on the vehicle model and the actual version of the part. Have work on the brake system carried out by a person with the appropriate knowledge and equipment.
1) Before installation
- Verify the cause of the fault. In electronically controlled brake systems, the problem may also be related to the power supply, wiring or associated components.
- Compare the markings, housing shape, mounting points and, depending on the version, connectors and connection points with the old part.
- Check for cracks, deformation, corrosion, damaged contacts and any signs of leakage. Do not allow dirt to enter open connections.
- Find out in advance what diagnostic checks, adjustments and bleeding the manufacturer requires for the specific type of part being installed.
2) Tools and materials required
In general, prepare suitable hand tools, a torque wrench, protective equipment, clean cloths and means of protecting open connections. Depending on the version, compatible diagnostic equipment and brake hydraulic system service equipment may be required. Select materials and service specifications according to the documentation for the specific vehicle.
3) Step-by-step installation procedure
- Park the vehicle safely, secure it against movement and prepare a work area where there is no risk of contaminating the components.
- If the system condition allows, record the diagnostic findings and any information required for subsequent commissioning.
- Switch off the ignition. Disconnect the battery and release any residual pressure in accordance with the manufacturer’s service procedure.
- Access the part according to the vehicle documentation. Before disconnecting anything, record the routing and position of the connected components.
- Clean the area around the connections. If opening the hydraulic section, prepare to protect the connections from dirt and catch any fluid that may leak.
- Carefully disconnect the connections appropriate to the actual type of part. Release connectors using their locking tabs, not by pulling on the wires.
- Release the fasteners and remove the original component without straining nearby lines. Compare the two parts once again.
- Fit the replacement part without putting it under strain. Tighten the fasteners to the manufacturer’s specifications and reconnect all relevant connections.
- If the hydraulic circuit was opened, refill and bleed it as specified. If the procedure requires diagnostic control of the system, use the appropriate equipment.
- Restore the power supply according to the manufacturer’s procedure and carry out any required adjustment, diagnostics and static function check.
4) Post-installation checks and test drive/function verification
Check the fasteners, connector locks, routing for strain and the tightness of any disconnected connections. Check brake pedal behavior, warning lights and diagnostic results as applicable to the system version. Do not drive the vehicle if there is a leak, abnormal pedal behavior or an unresolved brake fault. Carry out a test drive only after a successful static check, carefully and in a safe location.
5) Common installation mistakes + how to avoid them
- Fitting the wrong version: compare both the numbers and the design, not just the model name.
- Contaminating connections: work cleanly and protect open connections immediately.
- Damaging connectors or lines: do not use force and maintain the original routing without strain.
- Skipping bleeding or adjustment: follow the manufacturer’s requirements for the specific component type.
- Replacing the part without identifying the cause: check related components before installation so that the original problem is as unlikely as possible to persist.
Reasons why the part may become damaged
The following factors can generally damage brake system components; this is not a description of any faults found in the part offered:
- Moisture and corrosion, which can affect the housing, connections or electrical contacts.
- Mechanical stress, impact or improper handling during removal and installation.
- For electrical components, power supply faults, damaged wiring or water ingress.
- For hydraulic components, dirt and neglected maintenance, which can contribute to wear and leaks.
- Long-term operating and thermal loads, the effects of which depend on the design and conditions of use.
