Seat Leon catalytic converter scrap price and what happens when it breaks

A catalyst (more correctly, a catalytic converter) is an exhaust system unit that cleans fuel combustion products from harmful impurities before they are released into the atmosphere. As a result of chemical reactions of oxidation and reduction, toxic nitrogen oxides, hydrocarbon compounds and carbon monoxide are converted into nitrogen, water and carbon dioxide. The reactions in the catalyst proceed in the presence of oxygen and high temperatures in the presence of platinum group metals.

Seat Leon catalyst

Seat Leon catalysts are made out of one of the most high-quality materials and can serve for many years without the need for replacement. However, not everything is perfect and sometimes the catalyst can go bad due to various factors.

Reasons for the catalytic converter of Seat Leon to go bad

Among the usual warranty expiration dates, the catalytic converter can break accidentally. Thus, it is always recommended to perform the necessary service maintenance and check the vehicle regularly.

• With a complex internal structure and operating at high temperatures, the converter is susceptible to mechanical and chemical influences. Ceramic honeycomb, used to save money and achieve a smaller cell diameter, breaks down under shock loads, as a result of shaking on bad roads, moisture ingress into the exhaust system. The particles are trapped inside the cylinders, resulting in increased frictional wear.

• Poor quality fuel and oil leaks lead to burning of impurities on the honeycomb. The volume is filled with sulfur, paraffin and other substances. The active layer on the honeycomb grid overlaps and does not participate in the reaction, which reduces the efficiency of the catalytic converter. Deposits of impurities on the mesh are fused into lumps, destroying its structure. Instead of a catalyst, a plug is obtained that prevents gas from escaping.

• The consequence of damage is the obstructed exit of the exhaust gases. The quality of the fuel mixture decreases, which leads to a drop in engine power. The motor ‘feels’ worse. The speed does not rise above a certain value. It is more difficult to start the car. When the catalyst is not working at all, the start-off becomes simply impossible.

Some of the modern catalytic converters are bound to the computer inside of the car. And when the catalyst is not operating at its supposed to, the vehicle cannot go above 60 miles per hour.

Used Seat Leon catalytic converter cost

Many drivers choose a great option that can save some money anytime and anywhere. Selling the used Seat Leon catalytic converter to a local shop or online might be a great deal.
