How to Identify the Most Common Exhaust Problems

The exhaust system is an essential part of the running of any vehicle and also plays a safety function by directing all the exhaust fumes away from the car. It makes sure that all of the harmful emissions and particles are removed, improves the fuel economy of the vehicle and reduces the noise produced by the engine. If a car starts to experience exhaust problems it is vital that these are identified and dealt with quickly. This article highlights some of the more commonly experienced exhaust problems and how you can recognise them:

The Engine is Really Noisy

If you find your engine is becoming overly noisy you probably have an exhaust problem. The sound of a faulty manifold gasket is like a hissing or a tapping sound. When you start the car from cold the sound will be at its loudest and it will also increase when you accelerate.

A Fall in Power and Acceleration

You will find that an exhaust problem soon begins to affect performance. Your car will be more sluggish with slower acceleration from stationary and a lack of general power when changing speed. If you don’t have the exhaust leak mended the problem will just continue to get worse.

Reduced Fuel Efficiency

The fuel efficiency of a vehicle will go down as the problem of loss of power and acceleration gets worse. The car has to work harder and harder to maintain the same level of function and to run as it does when it has no exhaust problems. You will find that you will use more fuel and this will increase until you fix the problem. Although you may consider the cost of replacing the exhaust to be high, the cost of the extra fuel will outstrip this over time.

Rust

Exhaust systems are made from metal parts and so one of the most common causes of exhaust problems is rust. The materials used and the fact that the system is close to the ground where it is exposed to moisture and gritty conditions means it is particularly vulnerable. Once rust takes hold in the system it leads to more and more damage and the formation of holes and cracks. You can easily see rust problems on the exhaust with a simple visual inspection but if the rust is severe enough to cause holes you will start to hear loud roaring engine noise or hissing as gas escapes. This will definitely need professional attention.

Smell of Burning from the Engine

If you start to smell burning it is likely that the gasket has failed and is starting to leak near engine parts or wiring. Anything that is made of plastic is likely to burn because of the heat of the exhaust gases and this is what causes the smell. You may also see smoke. You should get the system checked as soon as you smell burning as this poses a serious safety risk.

Loose Parts

Parts will loosen or wear out over time. This is normal and is caused by rust, knocks from the road or just simple wear and tear. Most issues with loose parts are cheap and easy to sort out but if the loose part is inside the system and hard to find it may be that a replacement is needed.

Something quite small can sound really alarming and if you notice this issue it is likely that something is loose inside. It could be that the system is misaligned. Just take your car into the garage and have it checked.

Normal Wear and Tear

Just like any other part of the car the exhaust system is not exempt from the effects of wear and tear. In fact, for all of the other problems we have discussed, wear and tear can be a contributing factor. There are parts of the exhaust system that are more susceptible such as the exhaust manifold and the oxygen sensors.

  • Exhaust Manifold – this is the part of the exhaust system that is responsible for removing noxious gases from the engine and if it is damaged these gases can enter the body of the car and affect the driver and passengers. Hissing noises can be a sign that this part needs replacement and must be dealt with quickly.
  • Oxygen Sensors – these measure the amount of oxygen present in the system and work on adjusting the ratio of air to fuel to maintain fuel economy. If they start to fail these readings are not accurate and fuel consumption increases and you should take the car in to the garage to have them replaced.

Blockages

Blockages occur from time to time and have many different causes. It could be that there is a soot/carbon build up inside or that debris has entered the pipe. Often a minor blockage will just be spontaneously expelled but if the obstruction is large it can lead to poor function.

Unless you have a big blockage the signs can be hard to spot. Chugging noises can mean that something is in the system. If the blockage is large the car will run sluggishly and strain as if you are in too high a gear. You will experience increased revs and a drop in fuel economy.

If there is a smell of sulphur and/or the engine is getting hot it could be that the catalytic converter is blocked and gases are trapped in the system.

If you think you may have a blockage in the exhaust system you should take your car into a garage straight away. A professional will be able to assess the car and give it a thorough inspection in order to identify and repair any problems.

    Knowledge, value for money, and most importantly truly honest.

    Having had a long recurring issue with my VW California i was recommend to Volksmaster Van Centre Oldham.
    Fantastic, professional service from start to finish.
    From booking in and being kept up to date by Stacy, to the explanation of the issue and how they resolved it by Nathan.
    Would highly recommend all the team at Volksmaster.

  • Great service. Good communication and very knowledgeable. Kept me informed of everything and let me know exactly what the problem was and how to prevent future problems with the DPF filter on my Golf diesel. Also cleaned the car for me for no extra charge. Highly recommended.

    Another Visit to Volksmaster, another happy experience! Only went for wheel balancing this time, however once again their service was fantastic. They gave me readings of each wheel before and after each one was balanced, and the car drives bang on now! Will see you next time the car comes in for a service.

  • I had quite a bad central locking fault on my Caddy, which was a real pain for me. Volksmaster did a cracking job to find and fix the fault and went above and beyond in all their service. Very friendly and knowledgeable staff also. Cracking job and service from Volksmaster, would highly recommend.

    Attended the garage recently on two separate occasions (different reasons). Staff were helpful, polite and informative they didn’t speak to me like I was an idiot, from booking the car in to collecting it later. The garage and forecourt was clean and tidy giving a good impression. Would highly recommend this garage

  • Best garage around. Not only diagnosed the issue quickly but fixed it within a few days and even fixed a few electrical problems free of charge. Other garages couldn’t find the issue and one garage nearly had me recon my dsg gearbox at a cost of 3k. Highly recommended don’t wast your time at other garages like I did.

  • These guys are the real deal! 5 star. Constantly going the extra mile. Knowledgeable, patient, honest, down-to-earth and they know their VWs inside out. My van is back today from them, super clean and smelling great.
    So happy to have discovered their Bury branch, they gave my Volkswagen T5.1 van some seriously needed TLC and it drives like a new vehicle.
    I won't go anywhere else after so many dodgy cowboy garage experiences... now discovering these guys is like a diamond in the rough!! Don't hesitate to use them for any of your VAG needs. I'll be back.
    Cheers, Hannah.

    Excellent service at Volksmaster Bury. Took my Audi TT because there was water leaking into the footwells but I had no idea where from. They found the leak within an hour, replaced my windscreen and had it all sealed. They even cleaned all the mould from the carpets and dried it out as much as they could. Prices are fair and Mike was extremely helpful - highly recommended!

    Brilliant garage. They're honest, reliable, friendly and always try to fit you in at short notice if they can. You're given a estimate of the time that the job will take and they stick to it. No needless hanging around or constant calling to check on progress that I've had to do with some other garages. I trust the staff at Volksmaster to do a great job on time and to charge a fair price.
