Maybach 57 airbag control unit repair⁽¹⁾

What should be considered with Maybach 57 airbag control units?

The airbag control unit of the Maybach 57 evaluates the signals from the crash sensors, triggers the airbags and belt tensioners in an emergency and monitors the system. If a fault is detected, the airbag warning light indicates it.

The control unit is the central component of the restraint system. In a crash, it decides which airbags and belt tensioners are triggered, and it continuously checks the connected components for faults.

After an accident, the control unit stores crash data and locks itself. The airbag system is safety-critical, so work on it should be left to a specialist workshop. Airbag24 repairs your own control unit: you send it in, we inspect, repair and test it at our workshop in Berlin. The return shipment is made by UPS.

Which Maybach 57 generations are there?

The shop lists one series for the Maybach 57: the W240 Limousine, built from 2002 to 2012. Whether your vehicle falls within this production period can be checked from the year of manufacture on the vehicle registration document.

• W240 Limousine (2002–2012): limousine of the Maybach 57 from the W240 model line.

For an exact assignment, the vehicle's year of manufacture and the part number of the control unit count, not the model name alone.

The year of manufacture is therefore the first point of reference before you send in the control unit.

How do I identify my Maybach 57 airbag control unit?

The part number on the label of the control unit determines the exact version. The year of manufacture and the equipment of the vehicle also matter.

The label is located on the housing of the control unit. Read off the part number before having the unit removed. Together with the year of manufacture and the vehicle identification number (VIN), the version can be assigned.

Fault codes help with classification. Our verified sources list the following examples for this control unit:

• 9000 and 9001: control unit N2/7 (restraint system) defective
• 9076: CAN communication disrupted
• 9002: circuit 15R without voltage although terminal 15 is present

A fault code alone does not prove a defect. Only reading out and testing by a specialist workshop shows whether the control unit is affected.

Which airbag equipment does the Maybach 57 have?

Equipment data for the Maybach 57 lists driver and front passenger airbags, front and rear side airbags, and front and rear head curtain airbags. Which airbags are actually fitted in your vehicle depends on the equipment of the individual vehicle, not on the model name alone.

The restraint system combines these airbags with belt tensioners and the control logic of the control unit. The scope depends on year of manufacture, market and trim level; exact details are in the vehicle documentation.

The repair takes four steps. First, have the fault memory read out at a workshop. The specialist workshop disconnects the battery and removes the control unit. Then create a repair order online. After that, send in the unit.

Airbag24 usually processes the control unit within 3–4 working days: checking, repairing, testing. The repaired control unit returns with all vehicle data and is ready for use immediately after reinstallation — coding or programming is not necessary.
