How to Solve the Exhaust Pipe Abnormal Noise Issue in Mercedes-Benz E-Class?

[BethanyMarie]

Mercedes-Benz E-Class exhaust pipe abnormal noise causes and solutions: Exhaust pipe aging: When a car is too old, the exhaust pipe is prone to aging problems, leading to loosening, detachment, or holes, which eventually cause abnormal noise from the exhaust pipe. This situation is relatively simple to solve, requiring only re-fixing or replacing the exhaust pipe. Automobile three-way catalytic converter failure: If the car's three-way catalytic converter fails, it cannot properly purify exhaust gases, causing exhaust gases to block and compress inside it, leading to abnormal noise from the exhaust pipe. In this case, it is necessary to go to a repair shop or 4S store for professional inspection and repair. Automobile ignition system failure: If the car's ignition system fails, fuel cannot burn normally in the cylinder, and the car will experience symptoms such as weak acceleration, easy stalling, and abnormal noise from the exhaust pipe. In this case, a detailed inspection of the car's ignition system is also required.
