🔍 Technical Background

The Bang & Olufsen audio amplifier in the Bentley Continental GT MK3 is a high-performance digital amplifier designed for premium, multi-channel audio distribution. It integrates tightly with the vehicle’s CAN-Bus network and the central infotainment system.

These amplifiers are known for their precision and clarity, but due to the complexity of their design, they are also vulnerable to failure from:

• Voltage spikes during engine cranking

• Moisture ingress from trunk or under-seat locations

• Sleep mode and wake-up cycle errors

• Internal EEPROM or microcontroller malfunction

At Module Medics, we isolate the root cause using detailed circuit analysis, repair damaged traces or components, and test each unit in simulated Bentley environments to ensure compatibility and reliability.
