What Causes Volkswagen Tiguan Exhaust to Rattle While Accelerating? German carmaker Volkswagen designed and developed Volkswagen Tiguan in 2007. Its concept form was unveiled at the 2006 LA Auto Show and the first-generation Tiguan was unveiled at the 2007 International Motor Show Germany. Tiguan (“Tiger” in German) is one of the most popular compact SUVs due to its generous cargo space and comfortable riding experience. It uses upscale cabin material to design its interior. Moreover, easy-to-use infotainment system and standard advanced safety features have made it people’s choice. However, it needs special attention to run smoothly and last longer. Tiguan is powered by a typical internal combustion engine which generates mechanical energy by controlled detonations within the cylinders. The main function of your vehicle’s exhaust system is to get rid of the byproducts of the internal combustion. Moreover, it also helps to reduce air pollution by converting noxious gases into inert gases. However, a faulty exhaust system could not do its job efficiently as a result of which you might not be able to keep your vehicle operational. If the exhaust of your vehicle rattles when accelerating, then it is a clear sign of failing exhaust. Have a look at some of the most common reasons behind such kinds of abnormal behavior by the exhaust system.
Causes Of Exhaust Rattling When Accelerate: Malfunctions in the exhaust system not only affect the power output of your vehicle but also could kill the engine of your vehicle in the middle of nowhere. So, signs of a failing exhaust system in your Tiguan should not be overlooked. If the exhaust is making a rattling noise when accelerating, then something is clearly wrong with it that needs immediate attention. The following factors are primarily responsible for the emergence of rattling noise from the exhaust system of your vehicle.
Exhaust system leak: The heat generated due to the combustion process could damage the exhaust system of your vehicle. A damaged exhaust system could make a rattling noise when accelerating. So, conduct a visual inspection to detect and repair the malfunctions in the system. Rust could also damage vital components of the exhaust system. So, efforts should be made to prevent the deposition of mud and other kinds of contaminants on the exhaust system. Moreover, cracks or leaks in the exhaust should be repaired as soon as possible.
Damaged muffler: The primary job of a muffler is to reduce the noise emitted by the exhaust of an internal combustion engine. However, a damaged or failing exhaust muffler could not do its job as a result of which the exhaust could make unnatural noises while driving your vehicle. Moreover, malfunctions in the muffler could adversely affect the performance and fuel economy of your vehicle. So, check the condition of the muffler regularly and replace it if necessary.
Clogged catalytic converter: The catalytic converter is a crucial exhaust emission control device that helps to minimize the emission of toxic gases into the atmosphere. However, a clogged or damaged catalytic converter could not do its job efficiently as a result of which your Volkswagen Tiguan might fail an emission inspection. The emergence of rattling noise from the exhaust is a sign of a clogged or damaged catalytic converter. So, inspect the condition of the catalytic converter after a certain time interval and replace it if necessary.
Broken exhaust hangers:
Exhaust system hangers are used to support the exhaust pipes underneath your vehicle. These hangers are made of rubber which is an anti-vibration material and supports the weight of exhaust pipes. Loud exhaust making rattling or hissing sound is a clear sign of broken exhaust hangers. So, check the condition of exhaust hangers used in your Volkswagen Tiguan regularly. Broken hangers should be replaced immediately.
How to fix rattling exhaust Malfunctions in the exhaust system could adversely affect the performance and gas mileage of your Volkswagen Tiguan. So, signs of exhaust malfunction in your vehicle should not be neglected. Detect and repair the faults in the system as soon as possible to keep the vehicle in its top order. Take your vehicle to a reputed auto repair shop in order to fix the faults in your Volkswagen to keep it in working condition.
Final thoughts The exhaust system helps to get rid of the byproducts of internal combustion in a vehicle. Moreover, it also minimizes the level of harmful emissions. If the exhaust of your vehicle makes a rattling noise when accelerating, then it indicates that something is clearly wrong with it that needs immediate attention. Faults in the system responsible for the emergence of such kinds of unusual noise from the exhaust should be repaired as soon as possible.
