This guide provides a step-by-step walkthrough for replacing a faulty lateral acceleration sensor (G200) using VCDS Lite. If your VCDS Lite scan reveals error codes like “01423 – Lateral Acceleration Sensor (G200) 57-10 – Electric Circuit Failure – Intermittent” or “01423 – Lateral Acceleration Sensor (G200) 27-10 – Implausible Signal – Intermittent,” a sensor replacement might be necessary.
Locating the Lateral Acceleration Sensor
The lateral acceleration sensor is situated to the left of the steering column, requiring removal of the lower dash panel for access. Begin by removing the fuse box cover by the driver’s side door. While removing the adjacent side panel can provide more room, it might not be essential.
Accessing the sensor involves detaching the lower dash panel secured by clips on either side of the steering wheel. Disconnect the connectors for the light controls and the OBDII port before completely removing the lower dash.
The lateral acceleration sensor is housed in a brass clip to the left of the steering column, positioned below the larger yaw sensor.
Replacing the Sensor
The sensor is held in place by a brass clip. Unplug the sensor’s electrical connector by pressing the clip and pulling gently.
To release the sensor, carefully lever down the back of the brass clip using a screwdriver. This will free the sensor from its mounting.
Install the new sensor by positioning it correctly within the clip and pushing the clip back into place until it secures the sensor. Reconnect the electrical connector, ensuring a firm connection.
Reassembly and VCDS Lite Confirmation
Reassemble the lower dash, side panel, and fuse box cover. After installation, use VCDS Lite to clear any existing fault codes and monitor the sensor’s readings to confirm proper operation. A test drive should also be conducted to verify the warning light no longer illuminates.
Further Troubleshooting and Resources
If the issue persists, a registered version of VCDS might be required for a more comprehensive diagnostic and reset procedure. Additional resources for troubleshooting and potential sensor repair can be found in online forums and guides, such as those focusing on VW/Audi models. Always consult reputable sources before attempting any repairs.
