If you're an Audi S4 owner, you may have experienced the dreaded AWE resonator rattle. This issue is not uncommon, and it can be frustrating to deal with. The AWE resonator rattle is caused by a loose weld in the exhaust system that allows the resonator to move around and make noise. In this article, we'll discuss the causes of the AWE resonator rattle, how to fix it, and how to prevent it from happening in the future.

What Causes the AWE Resonator Rattle?

The AWE resonator rattle is caused by a loose weld in the exhaust system. The resonator is a component in the exhaust system that is designed to reduce noise levels. The rattle occurs when the resonator is allowed to move around due to the loose weld. The movement of the resonator causes it to hit against other components in the exhaust system, which creates the rattling noise. Another possible cause of the AWE resonator rattle is a broken hanger. Hangers are used to hold the exhaust system in place. If a hanger is broken, the exhaust system can move around and cause the resonator to rattle.

How to Fix the AWE Resonator Rattle

There are a few different ways to fix the AWE resonator rattle. The easiest way is to take your car to a mechanic and have them weld the loose weld. This will permanently fix the issue and prevent the resonator from moving around. If you're handy with tools and want to fix the issue yourself, you can try using a muffler clamp to secure the resonator in place. This is a temporary fix, but it can help reduce the noise levels until you can get the issue permanently fixed. If the issue is caused by a broken hanger, you'll need to replace the hanger. This is a relatively easy fix, but you'll need to make sure you have the right replacement hanger for your specific Audi S4 model.

How to Prevent the AWE Resonator Rattle

Preventing the AWE resonator rattle is relatively easy. Regular maintenance of your Audi S4 will help prevent the issue from occurring. Make sure to have your exhaust system inspected regularly and have any loose welds or broken hangers repaired as soon as possible. Another way to prevent the AWE resonator rattle is to upgrade your exhaust system. Upgraded exhaust systems are designed to be more durable and less prone to issues like loose welds and broken hangers. If you're considering upgrading your exhaust system, make sure to do your research and choose a reputable brand.
