REASONS BEHIND VOLKSWAGEN CATALYTIC CONVERTER FAILURE IN ROWLETT
Catalytic converter in Volkswagen removes the harmful gases from the exhaust.
In general, the catalytic converter sits ahead of the muffler in its exhaust system.
However, it converts harmful gases into less harmful emissions before exiting the tailpipe.
When the converter is failed, you will more likely end up with the worst driving.
The below points define the reasons for the failed catalytic converter in Volkswagen.
Fuel entering the exhaust system
For your engine to run properly, it requires an exact ratio of fuel to air.
If too much fuel enters the exhaust system, the unspent fuel ignites and reaches the catalytic converter causing it to heat up.
Deteriorated spark plugs
When the spark plug misfires, it causes unburned fuel to enter the exhaust system.
The unburned fuel ignites inside the converter and melts down the ceramic catalyst.
Lack of engine tune-up
When the engine gets out of tune, the entire car will undergo more wear and tear.
An improper air/fuel mixture will affect the exhaust coming from the engine and fail the catalytic converter.
Coolant in the exhaust system
When the cooling system is failed, the engine runs hotter than it should and cause: Cracked manifold gasket Broken cylinder head gasket
Coolant in the exhaust system will result in the accumulation of carbon deposits on the catalytic converter.
Failed oxygen sensor
An oxygen sensor failure can lead to incorrect readings of exhaust gasses.
Bad sensor can cause a too rich or too lean condition and the converter unable to convert the hydrocarbons into safe elements.
Conclusion
For avoiding the replacement of catalytic converter, maintain the Volkswagen regularly.
Consult with a reputed mechanic for inspecting the converter and fixing it accordingly.
