01224: Front Crash Sensor G283

Hardware fault

What 01224 means

Satellite sensors sit at the front of the car so they feel a frontal impact before the controller in the cabin does. G283 is the driver side unit. The controller compares what the satellite reports against its own internal sensing to decide whether and how hard to deploy, so it disables the system when that input is not trustworthy.

Mounted up front means mounted in the weather. The sensor and its connector live near the radiator support or the inner structure, where road spray, salt, and heat reach them constantly. A minor front-end hit that barely marks the bumper cover can still move the bracket enough to affect how the sensor reads.

Common causes

• Corrosion inside the sensor or its connector after years of road spray and salt
• A bent or loose mounting bracket from a low-speed frontal impact
• A sensor reused through a previous collision repair rather than replaced
• Connector damage or a broken conductor from bumper, radiator, or condenser service
• Internal sensor failure after a long service life of heat and vibration

Crash data or hardware fault?

01224 is a live hardware and signal fault, so it reflects what the controller sees at this moment. Fix the sensor or its connection and the code stops being reported. Crash data is the permanent record written after an actual deployment, and that one does not respond to parts replacement at all.

Does our reset clear it?

Erasing 01224 will not repair a corroded sensor or a bent bracket, and the controller stores it again at its next check. Replace or repair the sensor first. Our mail-in module reset is for a controller locked on crash data, and front satellite sensors are usually replaced as part of that same collision repair.

Which makes throw it

Our lookup carries 01224 on the Audi side. Confirm the code against the index matching the vehicle before ordering, because front satellite sensors vary by platform and are not interchangeable.

What to do next

Get eyes on the sensor and its connector first, since corrosion and a bent bracket are both obvious once the bumper cover or the wheel liner is out of the way. Confirm the mounting surface is flat and the fastener is properly torqued, because a sensor that is not solidly mounted gives readings the controller rejects. With the mounting and wiring verified and the code holding, install a genuine OEM Audi front impact sensor. Related codes: 01222, 01226, B1113.
