A catalytic converter is an essential part of your exhaust system. Its job is to change harmful substances in a car’s exhaust gasses, such as carbon monoxide nitric oxide, and hydrocarbons, into less harmful gases.
Below are the top three symptoms that could indicate you need to replace your catalytic converter:
The smoke from your exhaust is heavier or darker than normal.
You smell something similar to rotten eggs or sulphur coming from your car’s exhaust.
You notice a reduction in engine performance.
Our certified mechanics will:
Raise your car completely off the ground, making sure that the exhaust has had time to cool down before they begin the replacement.
Locate the catalytic converter. It usually looks like a box in the middle of the exhaust system underneath the car.
Remove the catalytic converter, inspect it and fit a replacement if necessary
Test the new catalytic converter, taking care to double check that the replacement catalytic converter is up to the correct specifications for the vehicle’s emissions standards.
Hey Fixter, can I drive with a broken or missing catalytic converter?
Your car will be drivable, however bad catalytic converters are terrible for the environment and can cause further damage to your car. If you get caught with a broken catalytic converter you may be fined by the police.

Wolverhampton, situated in the West Midlands region of England, is a bustling city known for its industrial heritage and vibrant community. With a population of approximately 260,000, it is one of the largest cities in the region.
When it comes to car ownership in Wolverhampton, the data reveals some interesting trends. The Ford Fiesta takes the top spot as the most popular car in the city, favored by Wolverhampton residents for its reliability and fuel efficiency. Following closely behind are the Volkswagen Golf, Vauxhall Corsa, BMW 3 Series, and the Audi A3.
In addition to these popular choices, Wolverhampton residents also show a preference for SUVs and crossover vehicles, such as the Nissan Qashqai and the Range Rover Evoque. This reflects the city's diverse needs, from urban commuting to outdoor adventures in the nearby countryside.
Wolverhampton boasts a significant number of licensed vehicles, with approximately 180,000 cars registered in the city. This high number reflects the city's reliance on private transportation and the need for efficient and reliable car maintenance services.
Wolverhampton is divided into several postcodes and suburbs, each with its own unique character. Some notable areas include WV1 (City Centre, All Saints, and Blakenhall), WV3 (Penn, Warstones, and Merry Hill), WV6 (Perton, Pattingham, and Tettenhall), and WV11 (Wednesfield, Fallings Park, and Wood End).

A catalytic converter is a key component of your exhaust system. It changes harmful substances in a car’s exhaust gasses, such as carbon monoxide nitric oxide, and hydrocarbons, into less harmful gases, such as water vapour. Every car registered in the UK must have a catalytic converter fitted by law. It became standard for petrol vehicles in 1992, and 2001 for diesel cars.
A typical catalytic converter is made of ceramic blocks with a porous structure. By coating the pores with a selection of valuable metals: platinum, rhodium and palladium, they act as a filter to break down the toxic exhaust gases produced by burning petrol.
The metal coatings work far better as filters when they’re heated, so their position next to the engine offers the ideal environment for just that. The converter can then perform the chemical reaction required to break down the poisonous gasses into less harmful products with much greater ease.
A catalytic converter will usually need to be replaced after 70,000-100,000 miles, or if you begin to experience any of the above symptoms. Regular maintenance and checks (including an MOT) will determine whether you need to replace your converter or if it’s good to go for a few more miles.
How you drive, and the typical usage of your car, will affect its lifespan too. Your converter could wear out quicker if your car is predominantly used for short journeys in stop/start traffic. Your converter works better at a required temperature, so if it’s not getting the chance to heat up properly, it isn’t going to be as efficient. This could shorten its effective life.
Your vehicle’s emissions will be measured during your MOT test. If your car is found to break the legal limits, then that’s an immediate fail.
In 2020, almost 1.3 million vehicles failed their MOT test last year due to dangerously high emissions. If you’re trying to keep your motoring costs down, then MOT retests are easily avoidable with regular checks and good car maintenance.

Most catalytic converters will last the lifetime of a vehicle. But in some cases, a converter will go bad and need to be replaced. Almost all problems with a catalytic converter are due to an engine issue. It is usually caused by excess fuel entering the exhaust system due to an incorrect air/fuel mixture, failing spark plugs, incorrect engine timing, a faulty oxygen sensor, or other issues where fuel leaves the engine’s combustion chamber unburned.
When this happens, the catalytic converter gets too hot and begins to melt, causing significant performance problems. Without proper maintenance, carbon deposits can also clog the catalytic converter, or worst case, block it completely.
The expected lifespan of a catalytic converter is usually between 70,000 and 100,000 miles. Regular maintenance and checks (including an MOT) will determine whether you need to replace your converter or if it’s good to go for a few more miles.
How you drive, and the typical usage of your car, will affect its lifespan too. Your converter could wear out quicker if your car is predominantly used for short journeys in stop/start traffic. Your converter works better at a required temperature, so if it’s not getting the chance to heat up properly, it isn’t going to be as efficient. This could shorten its effective life.
Usually, there a few signs you can look for:
Significantly reduced engine performance.
Dark smoke is coming from the exhaust.
Poor fuel efficiency.
If you experience issues while accelerating.
If you can smell sulfur (rotten eggs) coming from your car.
When the ‘check engine’ warning light illuminates.

This can vary from car to car and from driver to driver, however the estimated lifespan of a catalytic converter is between 70,000-100,000 miles, or if you begin to experience any of the symptoms previously mentioned.
Your car will most likely still be drivable, however bad catalytic converters are terrible for the environment, and driving without one is even worse. A blocked or damaged converter can cause further damage to your car, resulting in a more expensive repair in the long run.
There are strict regulations and laws around vehicle emissions, therefore if you get caught by the police with a broken or missing catalytic converter you may be fined.
Failing to replace a catalytic converter can result in more damage to your car, poor fuel efficiency and a potential fine from the police. If the converter has begun to function poorly due to it being clogged up, it will cause the vehicle to run extremely poorly.
