Should you consult a dealer service department before replacing a catalytic converter due to federally mandated warranty coverage on Volkswagen Passat?

Since there is a Federally required warranty on the emissions-related parts such as the catalytic converter, it would be prudent to contact a dealer service department before replacing the converter at your own charge. An emission control device installed in the exhaust system to reduce the pollutant level in the exhaust gasses is the catalytic converter in which a three-way catalyst design is used with the coating of platinum and rhodium to minimize the amount of oxides of nitrogen, hydrocarbons, and carbon monoxide in the exhaust gasses. Catalytic converter testing equipment is also expensive and advanced and in case of a suspected malfunction, one should visit a dealer or a certified emissions testing facility and have his diagnosis and repair. When servicing underbody parts, inspection of converter leaks, corrosions, dents and other damages, inspection of welds and flange bolts between converter and exhaust system, and replacement of converter in case of damages. A plugged catalytic converter may be investigated with the help of a vacuum gauge; it is connected at an intake manifold vacuum source and the engine is warmed and the vacuum readings at idle condition and at accelerating engine speed up to 2000 rpm are noted and any significant decrease noted. To replace, ensure that the vehicle is upheld on jackstands, unplug the electrical connections of the oxygen sensor, remove flange bolts that connect the exhaust pipe and exhaust manifold, and hold the exhaust pipe without excessive bending of the flex pipe. Disconnect the catalyst converter with the exhaust system, clean the mounting flanges, and put in place fresh gaskets, taking care not to overload the mountings and having them perfectly aligned and devoid of stress when tightening the clamps during re-installation.

Volkswagen Passat Catalytic Converter

The Volkswagen Passat Catalytic Converter purifies the exhaust of the car, ensuring that poisonous gases do not escape into the air inhaled by people. Within a small stainless shell, there is a honeycomb core lined with platinum, palladium, and rhodium, which accelerates the chemical reactions transforming carbon monoxide and unburned fuel into carbon dioxide and water and returning nitrogen oxides to harmless nitrogen. Early designs were two-way and only dealt with carbon monoxide and hydrocarbons, but the subsequent three-way design also addresses nitrogen oxides, thus making the later design the standard on all current Volkswagen sedans. The distinction is important since leaner engines would require the three-way unit in order to comply with tight emission regulations without negatively affecting power or fuel consumption. The Catalytic Converter may last as long as a normal Volkswagen, and with regular oil changes and a healthy ignition system this should be a minimum of 80,000 miles. Overheating, clogging, or cracking the part may be due to misfires, coolant leaks, rich mixtures, or road debris, and the vehicle may provide indicators such as rattling sounds, slow acceleration, dark exhaust, or a recalcitrant check engine light. When these signs are exhibited on a Passat, any further driving may suffocate the engine as the exhaust is not released through the broken Catalytic Converter, and therefore the only solution is to replace it. Early maintenance prevents a Volkswagen from running dirty, allows it to pass emission tests without any drama, and helps save the environment.

Choose OEM Catalytic Converter for superior quality and long-lasting durability. They match the Volkswagen's factory specifications exactly and pass strict quality control. If you plan to replace Catalytic Converter on your Passat, put OEM at the top of your list. You'll get the right fit, reliable performance, and peace of mind.

Volkswagen Passat Catalytic Converter Parts and Q&A

Q: Should you consult a dealer service department before replacing a catalytic converter due to federally mandated warranty coverage on Volkswagen Passat?
A:
Since there is a Federally required warranty on the emissions-related parts such as the catalytic converter, it would be prudent to contact a dealer service department before replacing the converter at your own charge. An emission control device installed in the exhaust system to reduce the pollutant level in the exhaust gasses is the catalytic converter in which a three-way catalyst design is used with the coating of platinum and rhodium to minimize the amount of oxides of nitrogen, hydrocarbons, and carbon monoxide in the exhaust gasses. Catalytic converter testing equipment is also expensive and advanced and in case of a suspected malfunction, one should visit a dealer or a certified emissions testing facility and have his diagnosis and repair. When servicing underbody parts, inspection of converter leaks, corrosions, dents and other damages, inspection of welds and flange bolts between converter and exhaust system, and replacement of converter in case of damages. A plugged catalytic converter may be investigated with the help of a vacuum gauge; it is connected at an intake manifold vacuum source and the engine is warmed and the vacuum readings at idle condition and at accelerating engine speed up to 2000 rpm are noted and any significant decrease noted. To replace, ensure that the vehicle is upheld on jackstands, unplug the electrical connections of the Oxygen Sensor, remove flange bolts that connect the exhaust pipe and exhaust manifold, and hold the exhaust pipe without excessive bending of the flex pipe. Disconnect the catalyst converter with the exhaust system, clean the mounting flanges, and put in place fresh gaskets, taking care not to overload the mountings and having them perfectly aligned and devoid of stress when tightening the clamps during re-installation.
