9062 on Mercedes-Benz
Airbag Device Control - Wrong/Incorrect Coding
9062 on Mercedes-Benz vehicles indicates airbag device control - wrong/incorrect coding. Au7o has documented this code across 1 Mercedes-Benz model — most commonly on CLA. 9062 is a Mercedes-Benz SRS (Supplemental Restraint System / airbag) control-unit fault code, titled "Device control airbag, wrong code," and corresponds to OBD-II code B1062. It indicates the airbag control module's coding/configuration does not match the airbag device(s) actually installed in the vehicle — typically logged after a control unit is swapped, replaced, or not properly coded to the vehicle, causing the SRS warning light to illuminate. Typical repair costs on Mercedes-Benz range from $80 to $400, depending on the specific model and root cause.
Common Causes of 9062
- •Airbag/SRS control unit was replaced or swapped but not coded (SCN-coded) to the specific vehicle
- •Control unit installed from a different model, year, or specification with mismatched variant coding
- •Incorrect or incomplete software/variant coding after a repair or retrofit
- •Mismatch between the control unit's stored configuration and the airbag/restraint hardware fitted (e.g., changed airbag or seat option)
- •Corrupted control-unit memory or failed coding/initialization procedure
- •Wiring/connector or component fault causing the module to read an unexpected device configuration

Mercedes-Benz CLA(1 issue)
- Auxiliary (Backup) Battery Malfunction Warning2014-2023
CLA owners frequently see an 'Auxiliary Battery Malfunction' message on the dash. The CLA uses a small secondary 12V battery to support electronics and the start/stop system; it typically degrades after roughly 4-6 years. A weak auxiliary battery, or a charging fault (alternator/voltage regulator, loose connections), triggers the warning and can cause intermittent electrical glitches in the infotainment, lighting and start/stop function, sometimes with a stored 9062 fault.
