AFIL sensor 2 Citroën Peugeot 9653381080 6590W1

Description

Lane driving sensor AFIL number 2 for CITROEN PEUGEOT
cars
There may be a broken screw that holds the unit to the undercarriage – must be unscrewed

Part description

The AFIL sensor (lane monitoring sensor) is part of a system that evaluates driving in a lane and cooperates with the car’s electronics. This particular part is listed as AFIL sensor 2 and is intended for Citroën/Peugeot cars.

The advantage of searching by part number is the quick identification of the correct piece – in practice, the most common comparison is the matching of product codes directly on the part. The documents also contain a practical warning: the screw holding the unit to the undercarriage may be cracked, so drilling may be necessary during disassembly/assembly.

Installation recommendations

Generally/typically for this type of electrical sensor, the exact procedure may vary depending on the specific model and make of the car. Below is a practical procedure aimed at safe replacement and minimizing the risk of damage to cabling or fixings.

1) Before assembly (checks of used part)

• Compare the codes on the part with the old part: 9653381080, 6590W1 (possibly also 603.012).
• Check the connector (locking latch, pins, oxidation) and the condition of the cable input to the sensor.
• Inspect the body of the sensor and the holder (cracks, deformation, traces of impact or overheating).
• Account for the fact that according to the documents the screw holding the unit may be notched – prepare for the drilling option.

2) Necessary tools and materials (in general)

• Basic set of ratchets/bits and screwdrivers
• Tools for removing plastic clips/upholstery
• Penetrating agent (for hardened joints)
• In the case of a cracked screw: suitable drills or a screw extractor
• Electrical contact cleaner
• Protective gloves and goggles (especially when drilling)

3) Step-by-step assembly procedure

1. Secure the vehicle against movement and turn off the ignition.
2. Disconnect the battery (recommended safety procedure for electrical parts).
3. Get access to the sensor according to the specific design of the car (removal of covers/undercarriage, etc. – depending on the situation).
4. Disconnect the electrical connector of the sensor: first unlock the latch, then pull the connector off without prying the cables.
5. Unfasten the sensor. If the screw is stiff, use a penetrant and be careful not to damage the bracket.
6. If there is a problem with the screw: according to the documents it may be notched – in that case it will be necessary to drill it out. Drill while protecting surrounding parts and wiring.
7. Dismantle the old sensor and clean the mounting surfaces/holder (keep them dry and free of dirt).
8. Before fitting, compare the codes again and visually verify that the connector and mount match.
9. Place the new (used) sensor in the holder and fasten it.
10. Connect the connector – it must fit clearly and be secured.
11. Put back the removed covers/clips and check that nothing rubs and the wiring is not under tension.
12. Connect the battery.

• 4) Post-assembly checks and test drive/function verification

  • Visually check that the sensor is firmly attached and the connector is properly secured.
  • After turning on the ignition, watch for related system warnings.
  • If you have diagnostics, perform a check of stored faults and a basic verification of system function (depending on the car’s capabilities).
  • On a test drive, verify that the problem that caused the part to be changed does not return.

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

  • Disconnecting the connector by the cables → always handle by the body of the connector, there is a risk of pulling out the wires.
  • Screw pull/snap → use penetration, proper bit and adequate force; protect the surroundings when drilling.
  • Poor locking of the connector → after clicking, do a light tensile test.
  • Mechanical damage to the sensor during assembly → do not clamp the part in a vise by the body and do not hit it during handling in the undercarriage.

  Reasons why the part is damaged

  • Moisture and contact corrosion in a demanding operating environment (pollution, water, salt).
  • Damage to wiring or connector (loose harness, pull on cables, poor securing).
  • Mechanical stress – vibration, impact, deformation of the holder or surrounding parts.
  • Incompetent disassembly/assembly leading to tearing/scratching of fasteners (possible cracked screw mentioned in the documents).
