Restore the rich, premium sound of your Bentley with our expert amplifier repair service. This is a professional repair service for the high-end Bentley Naim Audio PA4 amplifier, part number 4W0035466 — not a replacement part.

🔧 This Is a Repair Service for Your Existing Unit

If your Bentley’s Naim premium sound system has stopped working or is producing poor audio quality, it’s likely due to a failure in the factory amplifier. Instead of replacing this costly unit, let Module Medics professionally repair it.

You ship your existing amplifier to our facility in Baltimore, Maryland, where it is diagnosed, repaired, and returned with a 12-month warranty. Typical turnaround time: 2 to 3 weeks.

⚠️ Common Symptoms of a Faulty Naim Amplifier

These factory Naim amps, while high-performing, are known to fail over time. Symptoms include:

• No sound from all or specific speakers

• Distorted or crackling audio output

• Amplifier won’t power on or randomly shuts off

• Intermittent audio dropouts

• “Naim System Failure” or “Amplifier Error” on infotainment screen

• Blown fuse with no visual cause

• System stuck in protection mode

• Speaker channels not balanced (e.g. louder on one side)

If you're experiencing any of these issues, your amplifier likely has one or more failing internal components — which our experienced team can identify and repair.
