Understanding the Symptom: High-Speed Whistling

High-speed driving in your Mercedes-Benz should be a smooth and pleasurable experience. However, the joy can quickly be overshadowed by a persistent whistling noise. This noise, often emanating from the windows or door seals, can be particularly bothersome.

  • Tools Required: Plastic pry tool, weatherstrip lubricant, torque wrench.
  • Parts Required: Replacement weatherstrips (for Mercedes-Benz C-Class W204, part number A20472702887; for Mercedes-Benz E-Class W213, part number A2137200500).

Examples of Mercedes-Benz Cars and Specific Problems

  • Mercedes-Benz C-Class W204 (2007-2014): Known for weatherstrip degradation.
  • Mercedes-Benz E-Class W213 (2016-2021): Occasional door seal alignment issues.

Diagnosis: Pinpointing the Problem

Step 1: Carefully inspect the window and door seals for visible damage. Step 2: Test the doors by closing them with a sheet of paper to gauge the sealing pressure. Step 3: Listen for the specific location of the whistling sound while driving.
