Mercedes-Benz Clock Spring Removal

In this guide, you will find the steps to replace the clock spring on a Mercedes-Benz vehicle. The video is based on the Mercedes-Benz C-Class W204 chassis, but other models’ clock spring replacement procedure is similar. The challenging part will be releasing the airbag from the steering wheel.

What will you need

• Clockspring Assembly
• Allen Wrench

Procedure

1. Disconnect the battery first to prevent the airbag from deploying. It could also trigger the airbag indicator warning light. See tips on disconnecting the battery here in this link: 2009-2013 Mercedes S-Class Main Battery Replacement. 
2. Remove T25 bolts on both sides of the back of the steering wheel. In other newer models, it doesn’t have holes in the back, but you use a screwdriver to release the airbag from its indents. 
3. Loosen bolts to remove the airbag. See tips here in this link to remove the airbag: Mercedes-Benz C-Class W204 Airbag Replacement Procedure. 
4. Disconnect the airbag connector from the steering wheel by pressing the clips to release it. 
5. Remove the 10mm Allen hex bolt that holds the steering wheel using the Allen wrench.
6.  Remove the steering wheel. You may mark it at the center to place it in the same angle position to prevent it from becoming off-center. 
7. Pull the clockspring. Disconnect the locking tab to release the clockspring assembly.  
8.  Install the new clockspring assembly.

Replacing the clockspring is easy. Make sure you follow the procedures provided in this guide for dismantling the steering wheel to save time and make it operable.

Airbag Light On

If the airbag light is on after replacing the clock spring, you can use the YOUCANIC Full System Scanner to reset the airbag light. This scanner can also read and clear fault codes through every vehicle’s control module.
