AFIL sensor 2 Citroën Peugeot 9659847280 6590W1

Description

Lane keeping sensor AFIL number 2 for CITROEN PEUGEOT cars
The screw that holds the unit to the undercarriage may be broken – it must be unscrewed

Part description

The AFIL sensor (sensor) is used for the lane monitoring system in selected Citroën and Peugeot cars. If you are dealing with malfunctioning lane assist or AFIL-related outages, this part is a good choice as an original used replacement part with matching markings.

It is often searched directly by part number, so always compare the markings on your original sensor when choosing – especially 9659847280 and 6590W1.

Installation recommendations

Note from practice (for this part mentioned in the documents): the screw that holds the unit to the undercarriage may be “checked” – in this case it is necessary to drill it out.

Generally/typically the exact procedure may vary depending on the specific car design and sensor access. Below is a practical procedure typical for mounting a sensor/electrical sensor of this type.

1) Before assembly (checks of the used part, what to compare with the old part)

• Compare the codes on the part (min. 9659847280, 6590W1) with the old sensor.
• Check the undamaged connector, snap elements, holder and sensor body (cracks, deformation).
• Check the condition of the wiring and the contact of the connector in the car (oxidation, twisted pins, broken wires).

2) Necessary tools and materials (in general, without specific extra parts)

• Basic set of ratchets/bits and screwdrivers
• Tools for removing plastic rivets/upholstery (trim tools)
• Penetrating agent (if the screws are rusted)
• Drill and a suitable drill bit (if the screw is “notched” and drilling is required)
• Čistič kontaktů (volitelně, při známkách oxidace)

3) Step-by-step assembly procedure

1. Secure the vehicle against movement and prepare safe access to the installation site.
2. Turn off the ignition and for safety when working on the wiring disconnect the battery (general recommendation).
3. Dismantle the necessary covers/parts of the undercarriage or the surrounding cladding so that the sensor is accessible (the specific range depends on the car).
4. Disconnect the electrical connector of the sensor – do not pull on the cables, release the connector lock.
5. Enable sensor attachment. If the screw is “notched”, proceed in a controlled manner: use a penetration tool, or drill out the screw so as not to damage the holder or the surrounding parts.
6. Remove the old sensor and clean the mounting surface/holder from dirt.
7. Before installation, compare the numbers and design of the new sensor with the old one again.
8. Place the sensor in the holder in the same position as the original and secure it with a fastener.
9. Connect the connector and check that the connector lock is properly engaged.
10. Reinstall all the removed covers/undercarriage and check that nothing rubs against moving parts.
11. Connect the battery.
12. Perform basic functionality verification (see below).
• 4) Post-assembly checks and test drive/function verification
  • Visually check that the wiring is not stretched and the connector is holding firmly.
  • After turning on the ignition, watch for a warning related to the lane keeping system.
  • If you have diagnostics, verify that the system is reporting without errors and the sensor is communicating (general recommendation).
  • During a test drive, verify that lane assist behavior has returned to normal (under conditions where it normally activates).

  5) The most common assembly mistakes + how to avoid them

  • Torn/”Notched” Fasteners – use the correct tools, penetrant and be careful when drilling to avoid damaging the bracket.
  • Not clicked connector – always check the fuse and the clearance in the connector after connection.
  • Cabling damage during handling – do not pull on the wires, guide the cable so that it does not rub against the edges.
  • Exchanging the part according to appearance – the codes (e.g. 9659847280 / 6590W1) are decisive, not just the shape.

  Reasons why the part is damaged

  • Moisture and contact corrosion (undercarriage environment and road debris can accelerate oxidation).
  • Mechanical damage from stones, unprofessional disassembly or incorrectly fixed covers.
  • Damaged attachment (torn or “snapped” screw, deformed bracket) that leads to incorrect seating.
  • Problems in the wiring (broken wires, loose pins in the connector) that can act as a sensor failure.
