Project Summary
Diagnosed and restored total audio failure on a 2021 Mercedes-Benz E350. Located a broken MOST fiber optic loop node caused by trunk water leakage.
1. The Vehicle & OEM Challenge
The customer brought in a Mercedes-Benz E350 with zero audio output across all sources.
2. Custom Engineering & System Design
Audio Matrix plugged in specialized Xentry diagnostic equipment to scan the MOST fiber optic ring.
3. Step-by-Step Technical Installation Breakdown
1. MOST Fiber Optic Loop Attenuation Test
Using an optical power meter, we measured light transmission across all 5 nodes on the Mercedes MOST ring.
4. Real-Time Calibration & Post-Installation Results
100% audio recovery with zero warning light messages on the Mercedes COMAND dashboard.

Installation FAQs for This Project
Why does a single broken module turn off all sound in a Mercedes?
Mercedes-Benz vehicles use a MOST fiber optic ring network where audio signals travel in a continuous series loop.
