The catalytic converter itself is a part of the exhaust system. Tracing it, you’ll find it somewhere between the tail pipe and intake manifolds. They almost always have a heat shield around them and an oxygen sensor somewhere before them. It is necessary for the catalytic converter to be before the muffler.

Do all diesels have catalytic converters?
Yes, many diesel cars have a catalytic converter, but not in the same way that the gas-powered car does. Some diesel engines contain a two-way catalytic converter with a diesel oxidization catalyst, but it could be a three-way design that adds an SCR reduction.
Do all diesel cars have catalytic converters?
A catalytic converter cleans harmful gases before they exit a vehicle's exhaust pipe. Catalytic converters are usually used with internal combustion engines fuelled by either petrol or diesel. They are fitted into most petrol-fuelled vehicles made since 1992 and most diesel-fuelled vehicles made since 2001.

How much is a VW catalytic converter?
The average cost of a catalytic converter replacement for a Volkswagen Golf is between $1,700 and $1,800, plus the labor costs of your mechanic.
Is catalytic converter worth replacing?
A catalytic converter in your vehicle converts bad emissions into harmless gas. The catalytic converter usually lasts around 10 years so that's when you should replace it. You should also replace the converter if you run into other apparent problems such as clogging, or physical damages.
What are the 3 most leading failures of a catalytic converter?
Diagnosing Converter Issues Most catalytic converter failures fall under one of three categories: Overheated, melted or broken converters. Coated/oil-fouled substrate.
Do AdBlue cars have catalytic converters?
The AdBlue® is injected upstream of each catalytic converter. These two catalytic converters are fitted in series. The first SCR catalytic converter is located on the engine. The second catalytic converter is placed underneath the vehicle body.
How can VW ensure that its diesel cars now comply with US emissions standards?
Volkswagen installed emissions software on more than a half-million diesel cars in the U.S.—and roughly 10.5 million more worldwide—that allows them to sense the unique parameters of an emissions drive cycle set by the Environmental Protection Agency.
Do diesels have catalytic converters in Australia?
Catalytic converters were introduced to Australian vehicles in 1986 to clean up the noxious exhaust gases produced by petrol engines. More recently they've also become common on diesel engines. They are fitted to a vehicle's exhaust system and resemble a small muffler.

yeah u can fun red fuel just fine, but in my truck the milage isnt as great. and the thing on your exhaust would be your muffler.
Why do cars need catalytic converters?
Cars need catalytic converters because they produce toxic emission that can damage the environment and once introduced into the air, it can cause acid rain which is toxic to humans. Other pollutants in this toxic gas can include Nitrogen oxides and Hydrocarbons.
Why are catalytic converters important?
Catalytic converters are important to your vehicle and it helps to treat the exhaust system of toxic gases, so they don’t get released into the atmosphere. Catalytic converters contain catalytic substances, and this helps to convert the carbon monoxide found inside the toxic gas into carbon dioxide and water – this helps to clean ...
Does a Diesel Car Need a Converter?
If your diesel doesn’t have a converter, then the toxic gasses can’t be removed from the gases coming from the engine. If you have a vehicle that hasn’t got a catalytic converter or the cat converter isn’t working properly so toxic gases can’t be cleaned, you’ll have really high emissions. If there’s an unacceptable level of harmful emissions leaving the vehicle, your vehicle will fail it’s MOT, emissions test or smog tests which are all the same thing. It’s important that you maintain the catalytic converter and the engine to keep it in top shape.
What is diesel engine?
As you know, diesel engines are built for efficiency meaning that they use a completely different fuel from gas engines, and they ignite differently. This may leave you wondering if they have a catalytic converter that can help to get rid of the toxic gases in the exhaust system. Diesel engines use diesel fuel, and this is atomized and then ignited using a glow plug.
Why are diesel oxidation catalysts used?
The Diesel Oxidation Catalysts works identical to the cat converter in a gas engine. It uses metals as catalysts to help convert carbon monoxide into co2 and water.
What is the purpose of the SCR in diesel exhaust?
The SCR which can also be referred to as the Diesel Exhaust Fluid uses an ammonia-based catalyst to break down Nitrogen Oxide which is then converted to Nitrogen and Oxygen which isn’t harmful to humans.
How does a diesel engine work?
The gas engine uses a spark plug to ignite its fuel while a diesel engine will convert the fuel into a gas and then it’s ignited using a glow plug. This makes sure that the fuel is burned efficiently, and the amount of water fuel is low.
Symptoms
The most common signs of clogged catalytic converter in VW Golf are: limited performance above a certain speed or loss of performance, irregular running of the engine, unusual exhaust gas odor, poor fuel economy, engine check light illuminates, and sometimes rattling noises.
Causes for catalytic converter failure in VW Golf
All catalytic converters fail eventually since its a wearing part. Over time, carbon deposits accumulate and clog up the catalytic converter, especially if the vehicle has racked up a lot of miles.
How to check for a bad catalytic converter in VW Golf?
Reading out the fault codes using a diagnostic device is relatively reliable. If you see any fault code from P0420 to P0424 or from P0430 to P0434 in the OBD2 scanner, it indicates a problem with the catalytic converter. However, this is not always the case, as a bad oxygen sensor can also trigger catalytic converter codes.
Use OBD2 scanner for diagnosis
Since VW Golf is equipped with on-board diagnostics (OBD), a fault diagnosis can provide initial indications of where the malfunction is located.
Conclusion
If your VW Golf has racked up over 100,000 miles and you see noticeable loss of performance with high fuel consumption, a defective catalytic converter should definitely be considered.
