Land Rover Fake Engine Noise

Solving Fake Engine Noise Issues for La Jolla Audio

At OEM Activations, we recently had the pleasure of working with La Jolla Audio, a premier car stereo shop known for high-end custom audio installations. They reached out with an interesting challenge—one that showcased the complexities of modern vehicle electronics and the expertise required to solve them.

 

The Problem: Fake Engine Noise and Aftermarket Subwoofers

Modern Land Rover vehicles include a system known as fake engine noise, or Active Sound Enhancement (ASE). This feature is designed to enhance the driving experience by generating artificial engine sounds through the vehicle’s speakers. While some owners enjoy the added dramatics, others prefer a more authentic experience—especially when upgrading their audio system.

The issue arose when La Jolla Audio installed an aftermarket subwoofer in a high-performance Range Rover SV model. Because this SV featured Signature Sound, it also came equipped with Active Road Noise Cancellation (ARNC)—a sophisticated system designed to counteract road noise using in-cabin microphones and sound processing. However, when the vehicle’s factory balance was altered by adding new amplification, the ARNC system misinterpreted the changes. Instead of canceling out unwanted frequencies, it created an unbearable booming noise.

 

The Solution: Coding Out the Noise

OEM Activations was brought in to solve the problem at the software level. Using advanced coding techniques, we were able to:

✅ Disable the artificial engine noise to eliminate unnecessary enhancements.

✅ Turn off Active Road Noise Cancellation, preventing the system from interfering with the new audio setup.

✅ Restore pure silence, allowing the custom audio system to perform exactly as intended—without factory interference.

 

The Outcome: Clean, High-Fidelity Sound

With these adjustments, La Jolla Audio’s customer was finally able to enjoy their upgraded system without unwanted noise interference. This is a perfect example of how factory settings, designed for stock vehicles, can sometimes become obstacles when upgrading to high-end aftermarket components.

By leveraging coding and vehicle programming expertise, OEM Activations ensures that customers can enjoy the best possible experience—whether that means activating hidden features or eliminating factory nuisances.
