Redex DPF Diesel Particulate Filter Cleaner, Clears Soot Blockages Fast, Reduces Emissions & Reactivates DPF, 250ml, Packaging May Vary

Product Information

No. If your car has a DPF, you are not allowed to remove it. Taking it out will mean that you fail your MOT. Update – October 2023– We have updated our product recommendations in line with some excellent new products that have been released in the UK market. Modern diesel vehicles require regular journeys and not just that, they require journeys which allow the engine to get up to optimum temperature which then allows all of the emissions systems to work at their best. Unfortunately, short, infrequent journeys are a huge problem for modern diesels which are equipped with DPF filters as they don’t allow the DPF and other emissions systems to work properly. The Coronavirus pandemic has resulted in most people working from home which has then culminated in their vehicles not being used anywhere near as much. When drivers are using their cars, they are generally being used for a weekly trip to the shops, school run etc. As well as the warning light, you’ll also likely notice a decrease in performance from your car. You may experience the following symptoms.

Modern diesel engines currently produce less carbon dioxide levels than petrol engines, however they produce much higer NOx levels. High levels of NOx are dangerous to the environment and can cause respiratory problems for humans such as inflammation of the airways. It’s for these reasons that systems such as DPF filters were introduced. How Does A Diesel Particulate Filter Work? Update – November 2022– Interestingly, modern petrol or gasoline vehicles are now being fitted with DPF equivalent type filters. Gone are the days or buying a petrol vehicle to avoid frustrations with exhaust filter systems. Motoring product specialists such as Liqui Moly, Wynn’s and Cataclean are now producing DPF like cleaning products for petrol and gasoline cars. It’ll be interesting to observe whether PPF’s prove to be as problematic as DPF’s have been for modern Diesel engines. Once the exhaust has reached the specific temperature, the vehicle will begin the regeneration process which consists of the soot inside the filter canister being burnt off to create more space inside the filter.We’ve been using Redex Diesel System Cleaner in our 100k mile Ford C-Max for a few months to see if it improves performance and economy. Does it work? Redex DPF Cleaner works to clear soot from your car’s particulate filter, reducing the likelihood of a fault and switching off the warning light. Easy and convenient to use, it means you don’t have to take your car for a trip on the motorway to burn off soot from inside the DPF. In terms of economy, it’s almost impossible to be absolutely definitive as no two weeks are subject to exactly the same usage, weather or road conditions. Our DPF Cleaner is available to buy from most motoring stores and select retailers, and online. How to Use Redex DPF Cleaner

Using a DPF cleaning additive as a preventative measure could potentially save you thousands in repair bills. Alternatively, you can add a shot of DPF Cleaner when the light comes on. Add a dose to your car’s fuel tank, drive as normal, and you should find that the light switches off without the need for that inconvenient trip to the motorway. Do I need DPF Cleaner for a petrol engine? A DPF system works sitting in between the vehicle engine and exhaust system. It’s a small to medium sized filter which catches exhaust soot and then stores it in the filter instead of it being pumped out of the exhaust and into the atmosphere.

Why is my car’s DPF warning light on?

You may notice a rough and different idle to your car engine. It may be jerky and unsteady when stationery, due to the gasses not flowing properly through the DPF filter.

You can also use the DPF cleaner in conjuction with cheaper diesel as opposed to using more premium diesel fuels at each fill up. Should I Use A DPF cleaner If My Warning Light Is Not On? The warning light is there to serve as an alert that the system requires attention. It’s really important to take action as soon as the light illuminates, failure to do so can result in an expensive repair bill.

How do I use DPF Cleaner?

Prior to the conception of DPF filters, those harmful exhaust gasses were being pumped straight out into the atmosphere. DPF’s have been fitted to comply with European emissions regulations and it is illegal to alter or remove the system. Another contributing factor to DPF problems is poor quality diesel fuel. The more expensive, premium fuels contain additional additives which help reduce the amount of soot build up. Why Should I Use A DPF Cleaner? It’s also a really easy to use product, just putting a single bottle of Redex cleaner in to the tank at each full-up, which soon becomes second nature. What have we found in the last few months of using Redex?

Yes, absolutely. The principle behind a DPF cleaner is to act as a preventative measure to help prevent major problems manifesting themselves accompanied an expensive repair bill. Using a DPF cleaner will cause no harm and even if your DPF is only very lighly full, the cleaner will improve fuel economy and engine performance. Can I Have My DPF Removed? Wynn’s, the US based company, have developed an outstanding reputation over many years. They produce a whole host of engine performance additives and this DPF cleaner scores highly for value for money. Impressively, this DPF cleaner is also suitable for use in biodiesel vehicles all the way up to B30. The key features of Wynn’s DPF cleaner are; Redex DPF Cleaner lowers the temperature the soot burns at, meaning it burns away during normal driving without you having to get your engine very hot. Generally, DPF cleaners begin to work pretty much straight away after being application. Research has shown that vehicles can start to show improved performance as little after 10-15 minutes after the DPF cleaner has been applied. Once you’ve applied the cleaner, you should start to see a noticeable improvement from your car. How Often Should I Use DPF Cleaner? We had no hesitation in trying this out, especially as just about everyone at Cars UK Towers has used Redex at one time or another, and were confident it was safe to use.

However, we know that this isn’t always convenient, and it’s not the most reliable way to take care of your car’s filter. Remember, you can use DPF Cleaner whenever required to prevent problems, or when the DPF warning light comes on. It’s a valid question as you’re shoving additives in to your fuel tank, but the fact is that Redex have been delivering their products for almost 100 years, and are happy to declare that “Redex products will never cause any damage or impairment to your car”, and will do nothing more than provide a “reliable engine-cleaning solution” for users. Which is reassuring. DPF cleaners are suitable for most diesel or biodiesel engines and they may require regular usage to keep the DPF clean. However, if you find that they aren’t as effective as you would expect, go on a “spirited” drive whilst keeping the RPM’s high. You could also drive on the motorway and keep the car in a lower gear whilst travelling at 60 to 70 MPH. This type of driving along with using the cleaner should help to keep it clean as long as there isn’t a fault with the DPF. The EGR valve (Exhaust Gas Recirculation Valve), sits in the engine bay and exhaust gasses flow through it before moving on through the DPF filter. Because diesel fuel is quite oily in it’s formulation, diesel cars often suffer from carbon build up in the engine. An EGR valve is a prime candidate for coking up with carbon and often results in reduced gas flow through the valve. Again, a common cause for EGR valve problems is frequent short journeys around town as opposed to motorway journeys.
