Mercedes-Benz Clock Spring Models & OE Numbers (Reference Guide)

Use this guide to identify potential OE part numbers for aftermarket Mercedes-Benz spiral cables. However, due to the high number of variations across models and features, final verification via the vehicle’s VIN is mandatory.

Common Symptoms of a Failing Mercedes-Benz Clock Spring

A faulty clock spring disrupts the electrical signals between the steering wheel and the rest of the vehicle. If a customer’s Mercedes-Benz exhibits one or more of the following issues, a Mercedes clock spring replacement is the most likely solution:

• SRS/Airbag Warning Light: This is the most critical indicator. A constant or flashing airbag warning light on the dashboard means the system has detected a fault in the circuit, and the driver’s airbag may not deploy in a collision.[6]
• Unresponsive Steering Wheel Controls: Buttons for volume, phone, cruise control, or menu navigation may work intermittently or fail completely. This is a direct result of broken internal wiring within the spiral cable.[15]
• Horn Malfunction: The horn may not sound at all, or only work when the steering wheel is in a specific position. This is a clear sign of a compromised electrical connection.[7]
• Audible Clicking or Grinding Noises: A rubbing, grinding, or clicking sound when turning the steering wheel can indicate that the internal ribbon cable of the clock spring is broken or binding.[16]
• ESP/Traction Control Errors: On some models, the clock spring assembly also houses the steering angle sensor. A failure can lead to error messages related to the Electronic Stability Program (ESP) or traction control systems.

Understanding the OEM Steering Column Recall (NHTSA #17V627)

In 2017-2018, Mercedes-Benz issued a major safety recall (NHTSA Campaign Number: 17V627) affecting nearly 500,000 vehicles across multiple model lines, including C-Class, E-Class, CLA, GLA, and GLC.[17, 18] This recall highlights the critical nature of the steering column’s components.

The official recall documents state that the issue stemmed from a combination of factors: insufficient electrical grounding of steering components and a **broken steering column module clock spring** due to wear. Under certain conditions, this combination could lead to an electrostatic discharge causing an inadvertent deployment of the driver’s airbag.[19]

This known OEM issue underscores the importance of sourcing high-quality, durable replacements. Our IATF 16949 certified aftermarket Mercedes-Benz clock springs are engineered with robust materials and undergo stringent testing to prevent the very type of wear-related failures that contributed to this widespread recall. By choosing our parts, you provide your customers with a reliable solution designed for long-term performance and safety.
