Actual Sensor Representation
Example Fitment Vehicle (Skoda Fabia Mk3 5-Door)
Fitment Location: Inner Door Panel / B-Pillar Structure
Part Overview & Specifications
Part Number: 4H0955557 (Always verify this exact match)
Component: Driver Side (Right / O/S) Airbag Impact Crash Sensor
Material: High-impact reinforced plastic casing, sealed internal accelerometer circuitry.
Placement & Function: This critical safety sensor is mounted within the driver's side door structure or B-pillar. It detects sudden deceleration and lateral impacts, immediately sending a signal to the SRS Airbag Control Module to deploy the side/curtain airbags during a collision.
Symptoms of a Faulty Crash Sensor
- Persistent SRS / Airbag Warning Light illuminated on the dashboard.
- Diagnostic scanner reveals trouble codes specifically relating to the "Driver Side Impact Sensor" (e.g., Signal out of range / No communication).
- Failure of the airbag system to pass MOT inspection due to active warning lights.
The Massive Benefit of Buying Original Parts vs Cheap Copies
When it comes to safety restraint systems (SRS), compromising is not an option. Cheap aftermarket copies often suffer from delayed response times, poor calibration, or complete internal circuitry failure, leading to airbags either deploying randomly or failing to deploy during an accident. By purchasing this tested, original factory part, you guarantee proper calibration while saving as much as 70% compared to buying new from the main dealer!
Fitment & Compatibility Chart
| Make | Model | Body Style | Exact Years | Fitment Notes |
|---|---|---|---|---|
| Skoda | Fabia (Mk3 / NJ) | Hatchback (5-Door) / Estate | 2015 - 2021 | Driver Side Right / O/S B-Pillar / Door |
| Volkswagen | Polo (6C / AW) | Hatchback | 2014 - 2021 | Must match part number precisely |
| Seat | Ibiza (6J / 6F) | Hatchback / Estate | 2015 - 2021 | Right Hand Side ONLY |
❌ WHAT THIS PART WON'T FIT: This sensor will NOT fit older Mk2 Fabia models (pre-2015) or vehicles requiring a left-side/passenger sensor, as the internal calibration and wiring harnesses often differ side-to-side. Do not purchase if your current part number does not read 4H0955557.
Installation, Tools & Repair Guide
Fitting Instructions
- CRITICAL: Disconnect the vehicle's negative battery terminal and wait at least 15-30 minutes for the SRS system backup capacitors to discharge entirely.
- Remove the interior door card or B-pillar lower plastic trim using a non-marring pry tool.
- Locate the original crash sensor bolted to the metal chassis framework.
- Unplug the wiring harness connector, ensuring you do not snap the safety locking tab.
- Unbolt the faulty sensor (usually a Torx or Hex bolt) and remove it.
- Install the new sensor in the exact same orientation, plug in the harness, and reassemble the trim.
- Reconnect the battery. An OBD2 diagnostic tool may be required to clear stored airbag fault codes after installation.
Required Tools: Torx/Hex socket set, plastic trim removal kit, 10mm spanner (for battery), OBD2 scanner.
Estimated Repair Time: 45 - 60 Minutes.
