Product Title
Audi A4 A5 S5 MMI Multimedia Control Module 8T0 035.462 - Used Original Parts
Diagnosis and Common Symptoms
From the workshop floor, the MMI 3G control module (J794) is a frequent point of failure in the B8 chassis. A faulty unit will typically break the MOST fiber optic loop, resulting in a complete loss of infotainment functionality. The primary customer complaint is a black or flickering MMI screen, no audio output from any source (radio, media), and non-responsive center console controls.
Diagnostic scans will often reveal "No Communication" with the Information Electronics Control Module 1 (J794). Common fault codes stored in other modules on the MOST ring include:
- 00384 - Optical Data Bus: Open Circuit
- 03175 - Invalid Data Set
- 03006 - Control Module in Protective Transport Mode (after a failed flash attempt)
Failure is often due to internal hardware faults on the main circuit board, sometimes triggered by liquid spills in the center console area or voltage irregularities.
