Responsible for breaking down your car’s harmful emissions into neutral compounds, your catalytic converter is essential to the environment. However, it’s also critical for the smooth running of your car, as a malfunction can affect the intake of air into the engine, and the efficient use of fuel. Read on for some of the signs that you need to ask your VW dealer about a converter replacement.
Do You Need to Contact Your VW Dealer About a New Catalytic Converter?
Previous Problems
Converters can last for over ten years, but they can also become clogged and damaged. There are a number of engine faults that can have a knock-on effect on the exhaust system, such as misfiring spark plugs, faulty valves that lead to engine oil or coolant leaks, or a sharp blow to the underside of the vehicle. If you know that your car has suffered from any of these problems recently, it’s sensible to get the converter checked out.
Rattling Sounds
The converter, or “cat” as it can be known, is covered in tiny pores, rather like a honeycomb. These are coated in platinum, palladium, and other precious metals that are used in the catalysing process. However, if it is damaged, pieces can break off and infiltrate the exhaust system. This may lead to a rattling sound underneath the car.
Bad Smells
A malfunctioning converter might also cause a smell of burning or thick black smoke from the exhaust. Not only will this make the drive less pleasant, but it’s also a sign that your exhaust system needs a diagnostic check.
Less Fuel Economy
A damaged or clogged cat won’t allow your engine to burn gas as efficiently and will let unburnt fuel into the exhaust system. If you find that your car is costing you more at the fuel pump, your converter could be the culprit.
Reduced Power
If the cat becomes clogged, it disrupts the air flow into the cylinders and unbalances the fuel-air mix. This will result in less power, especially noticeable when you accelerate or drive at speed. If there’s a sluggish response from the engine, schedule an appointment as soon as you can.
Without a fully functioning cat, your car won’t perform as well, and it could lead to more expensive problems further down the line. While a replacement could be the only solution, it could be fixed by flushing the exhaust system or other repairs. Either way, though, it’s important to act promptly, so schedule an appointment at Crain Volkswagen of Fayetteville and let our certified technicians guide you about the right course of action.
