Product Title

Mercedes Benz W222 W205 W213 Sound Amplifier Module – A2229005110 (Original Used Part)

Diagnosis and Common Symptoms

The sound amplifier module in the W222, W205, and W213 chassis is a high-duty cycle component responsible for processing multi-channel audio via the MOST fiber optic network. Failure in these units is frequently caused by thermal stress or moisture ingress in the trunk cavities. Common symptoms include a complete loss of audio output across all sources, the "Sound" menu appearing grayed out on the COMAND display, or intermittent popping and crackling noises through the speakers. Technicians often find fault codes such as U112E00 (Communication with sound amplifier has a malfunction) or B129C15 (Output for speaker has short circuit) when scanning the audio gateway.

Unlike low-quality aftermarket alternatives, these Genuine units ensure the correct impedance matching and signal processing intended by Mercedes-Benz engineers.

Frequently Asked Questions

Q: What symptoms indicate failure? A: The most common sign is a "System Unavailable" message when attempting to adjust volume, or a total lack of sound even though the head unit appears to be functioning. If you see light coming from the fiber optic cable but get no sound, the amplifier is the likely culprit.

Q: Does this require coding? A: Yes. As a Genuine Mercedes-Benz electronic component, this module must be synced to your vehicle's VIN and speaker configuration using Xentry or a compatible diagnostic tool (SCN Coding).

Q: Is this original? A: Yes, this is an authentic factory-fitted part. We do not stock "universal" or aftermarket amplifiers, as they cannot properly communicate with the Mercedes-Benz fiber optic network.
