2 Answers
Baojun 560 exhaust pipe popping noise fault reasons are as follows: Fuel line blockage and other faults: Fuel line obstruction, poor flow, rail pressure, etc., can cause abnormal noises in the exhaust pipe. Abnormal electric fuel pump or fuel filter blockage due to various reasons, hindered fuel delivery, etc. Fuel injector abnormality: Inherent quality faults, or blockages due to foreign objects, poor sealing, aging rubber rings, and other various issues can cause the exhaust pipe to make popping noises. Intake or idle control faults: Stepper motor, throttle valve body contamination or air leakage, abnormal sensors such as atmospheric pressure, temperature, throttle position, incorrect data leading to abnormal noises in the exhaust pipe.
I've been driving for over a decade and encountered many exhaust pipe noise issues, especially with SUVs like the Baojun 560. The most common causes are loose exhaust hangers or broken brackets. Last time my old car had the same problem - it made clanking noises while driving. Basically, road bumps loosen those screws or cause corrosion/breakage of hangers, making the exhaust pipe shake and hit the car body. Another possible reason could be leaks in the exhaust system itself, like hissing sounds from loose joints or internal components like muffler parts coming loose. If you notice similar noises after starting the car, stop immediately and tap the exhaust pipe to check if the sound changes - this helps preliminary diagnosis. Don't underestimate it - these noises aren't just annoying but may affect emissions or lead to costlier repairs. I recommend visiting a professional auto shop for inspection. Spending a small amount now can prevent further damage to other components.
