Investigating the Underlying Cause

A clicking noise emanating from the power seat adjustment controls is not only disconcerting but can also indicate underlying issues. Here’s what you might need to investigate:

  • Worn Out Motors: For models such as the Mercedes-Benz E-Class (2010-2016), wear in the seat adjustment motors can cause clicking noises.
  • Damaged Gears: Found in the C-Class (2014-2019), damaged gears within the seat adjustment mechanism can produce this sound.

Tools and Parts Required

For DIY enthusiasts, the following tools might be necessary:

  • Torx screwdrivers
  • A new adjustment motor (part no. A2049063802 for specific models)
  • Replacement gears (part no. A2048700874 for C-Class)

Step-by-Step Troubleshooting

  1. Identify the Noise Source: Ensure the noise is coming from the seat adjustment mechanism and not elsewhere.
  2. Inspect the Motors and Gears: Disassemble the seat controls to inspect for wear or damage.
  3. Replace Damaged Parts: Carefully replace any worn-out motors or damaged gears.

Advanced Solutions for Specific Models

Owners of the following models may face unique issues:

  • Mercedes-Benz S-Class (2013-2020): Check for loose cables connecting to the seat adjustment panel.
  • Mercedes-Benz GLA (2014-2020): Inspect the entire wiring harness for breaks or pinches that might cause the noise.
