The Symptoms of a Blocked DPF Filter
Modern diesel cars are all fitted with a Diesel Particulate Filter or DPF. A DPF is designed to help your car reduce its emissions by filtering out excess carbon waste from the engine’s exhaust system. A DPF is a legal requirement of all diesel car drivers, and while the filter is necessary for the efficient running of your engine, it can often cause issues when they become blocked. Unluckily for us, DPF filters love getting blocked. In this article, we’re going to go over what happens when you experience a blocked DPF, and how to fix and avoid a blockage in the future.
Here are the symptoms of a Blocked DPF Filter:
1. Your Car Feels Weaker
Because a DPF blockage directly affects your exhaust system and its ability to remove gas from your engine, this then stops your engine from working as powerfully and as efficiently as it could. No matter how much acceleration you pump into the engine, it will still feel weak due to its inability to expel the excess gas. The engine will use more of its energy trying to push the exhaust fumes out through the DPF, which leaves less energy for acceleration.
2. You Burn Through Fuel Quicker
Because your engine is not working as hard, you will naturally accelerate more to make up for the lost power. Not only does a blocked DPF filter make your engine use more fuel, but the acceleration that you do also is not as powerful due to the engine not being able to expel its emissions. This double whammy of decreased efficiency causes you to spend more money on fuel along with tiring your engine out at a must faster rate. Imagine forcing an old horse to run faster than it ever has in its youth, something will eventually give out.
3. Your Engine is Harder To Start
When a blocked DPF causes a build-up of gas in the engine that can’t go anywhere, this also causes a large build-up of pressure in both the engine and the DPF itself. If this happens, your engine will simply not want to start until that pressure is released. This is actually a good thing as if you were to drive the car with that amount of pressure built up inside the engine, this could cause major damage to the engine and potentially ruin your DPF altogether. This can also be more expensive than a simple DPF cleaning service.
4. Issues With Your Turbocharger
A blocked Diesel Particulate Filter will hinder the flow of gas through the exhaust system, preventing the gas from passing through the exhaust at the right rate. This causes the temperature of the gas to increase if it is not expelled fast enough, which heats up the housing around the turbine. This can cause damage to your turbocharger such as the gas leaking directly from the turbocharger because it has nowhere else to go. This then causes oil leaks and a decrease in efficiency with the way the turbocharger works. A DPF blockage may also cause the oil that is stored in your turbo system to carbonize, which can be dangerous for your engine.
5. The Engine Smells Strange
All this gas that has built up in your engine will not smell overly nice. Not only is this dangerous due to the raised potential of engine damage or even fires, but the odor that comes from these gases causes anyone who inhales some of these gases to become ill. Also, the smell may also disguise other tell-tale smells that arise if any other issues are affecting your cars, such as a burnt-out clutch or an oil leak.
Now, you may want to know how to avoid DPF being blocked.
This can be quite difficult for many drivers, especially urban motorists that predominantly drive in the city. City driving comes with a lot of stopping and starting and rarely gives you the chance to get up to any major speed. Short journeys are also problematic as this doesn’t give the engine enough time to reach a temperature where it can burn away the blockage. If you are a city driver, it can be a good idea to take your car for a spin on the motorway once in a while to give your engine the heat and power it needs to blow away any build-up of waste within the DPF filter.
It is also a wise move to get your fuel injectors checked to ensure that they are sending the correct amount of fuel to the engine and not tipping your air: fuel ratio too far in the favor of fuel. When you fill-up the engine with engine oil, make sure that you are getting the right kind of oil that helps your engine burn away the DPF residues. Look for an oil that has low SAPS (Sulphated Ash, Phosphorus, and Sulphur). These oils have a lower rate of ash formation, and therefore will not clock your DPF as quickly.
Then, what should we do if DPF is Blocked?
