6Q0 909 606 Lateral Acceleration Crash Sensor

What you get with your purchase

Your 6Q0 909 606 lateral acceleration sensor arrives coded to your vehicle and ready to fit. The sensor measures acceleration at right angles to the direction of travel and supplies the airbag control unit with the data the control unit uses to decide whether to deploy the side restraint systems.

The same sensor is listed under three numbers: the Volkswagen number 6Q0 909 606, the successor number 6Q0 909 606 K and the number 5WK4 2895 used by the supplier Siemens. If your vehicle paperwork or a quote shows only one of these numbers, it refers to the same part.

Technical background on how the sensor works, where it is mounted and why these sensors typically fail can be found on the information page for part number 6Q0 909 606.

Why we need your vehicle identification number

The 17-character vehicle identification number (VIN) is part of the ordering process because we use it to code the sensor to your vehicle before dispatch. Without it we cannot prepare the part – with it, the sensor leaves our workshop fully coded and only needs to be fitted.

The 6Q0 909 606 was fitted across many model ranges and build years – among them the Lupo, Polo, Golf 4, Beetle, Passat B5, Caddy, Fox, Sharan and the Transporter T5. The VIN pinpoints exactly which of those versions is yours, which is more reliable than giving the model and year of manufacture, because crash sensors across the Volkswagen Group look almost identical from the outside.

Fitting and safety

The crash sensor is part of the restraint system and therefore safety-critical. Have it fitted by a specialist garage: the airbag system must be de-energised before any work begins, and restraint systems call for hands-on experience.

Because the sensor reaches you already coded, no separate coding step is needed at the garage. It is fitted in the same position as the original part that was removed.

Airbag24 has been working on airbag systems for over 20 years and has repaired more than 20,000 control units. If the airbag warning light stays on after fitting, the cause usually lies not with the new sensor but with the wiring, the connector or the control unit – reading the stored fault codes will show which of these it is.
