What causes the exhaust pipe noise in Chery A5?
2 Answers
The reasons for the exhaust pipe noise in Chery A5 are as follows: Exhaust pipe blockage: Poor acceleration when stepping on the throttle and abnormal noise from the vehicle are caused by air filter or exhaust pipe blockage. Insufficient hydraulic oil: Engine noise, reduced power, shaking, and illuminated fault light indicate vacuum tube leakage. Noise when turning the steering wheel to full lock is caused by insufficient steering hydraulic oil or excessive steering. Exhaust pipe cracking: Noise from the exhaust pipe is caused by exhaust pipe gasket damage or pipe cracking. Cold start noise that changes when stepping on the throttle, and disappears when sprinkling water on the belt, indicates belt aging. It is recommended to have multiple issues inspected at a 4S shop.
I've been driving a Chery A5 for almost ten years. In the past, when I encountered strange noises from the exhaust pipe, it was usually due to a loose exhaust system or a leak at the connection. Once, when I started the car, I heard a thumping sound. Upon closer inspection, I found that the exhaust pipe hanger had aged and come loose, dangling under the car and causing the entire body to rattle. Once the hanger is loose, the exhaust pipe will bounce and hit the chassis, creating various noises. If there's a leak at the connection, it sounds like a puffing noise, possibly due to a damaged gasket or loose bolts. Internal issues, such as a perforated or cracked muffler, can also cause strange noises and, in severe cases, affect emissions and increase fuel consumption. I recommend first checking if the exhaust pipe is loose by gently shaking it by hand. If you're unsure, take it to a reliable repair shop immediately—they can diagnose the issue with professional equipment before it turns into a major problem. During regular maintenance, ask the mechanic to inspect the exhaust system to prevent such annoyances.
