The exhaust noise has suddenly become unusually loud. What is the right thing to do?

If your exhaust noise suddenly becomes unusually loud, it usually means there is a defect or damage in the exhaust system, such as a hole or a loose part. According to German traffic regulations, you must immediately check the exhaust system to find the cause (answer 1) and make sure any damage is repaired as soon as possible (answer 2). Continuing to drive with excessive exhaust noise is not allowed, as it creates unnecessary noise pollution and can be illegal. You are never permitted to just wait until the next vehicle inspection to address the problem. Taking immediate action ensures your vehicle remains safe and compliant with noise and emission laws.
