Wynn's 18985 5L Off-Car Diesel Particulate Filter Cleaner Removes Soot & Deposits From DPFs

Product Information

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? DPF filters are fitted to all modern diesel vehicles and were introduced around 2009 to comply with Euro 5 exhaust emissions rules, some vehicles were fitted with them slightly prior to this. Only Got 5 Minutes?

If the DPF filter reaches a certain percentage full level, your car will give you a warning light which will look something similar to the image below (The image will vary between car manufacturer but will generally look very similar) 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.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.

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?

How to unblock almost any DPF Filter

He went on to say, “We’re asking the ASA to clamp down on those advertising these dubious practices … But we’re also calling on the Government to make it illegal to remove these pollution filters in the first place”. As well as the warning light, you’ll also likely notice a decrease in performance from your car. You may experience the following symptoms. This will depend on the types of journey you do. If you drive on a motorway regularly for extended periods of time, you’ll need to use DPF cleaner less often than a typical “around town” driver. Wait for five minutes before restarting your car to find that the DPF warning light, glow plug light or engine management light switched off!

If your car is low on fuel, it may refuse to begin a DPF regeneration. It’s always good practice to ensure that the fuel tank in your car is sufficiently full. Aside from causing problems with the DPF regeneration process, running a car on low fuel can cause a whole host of other issues. What Happens During A DPF Regeneration? Founded in 1971, FoE is a federation of 74 groups from all over the world who are dedicated to saving the environment. One of their primary causes involves complaining to the ASA about the prevalence of adverts for DPF removal services.If you have a manual car I suggest second gear and a speed of around 50 mph or you can try third gear at around 80 mph. Express delivery option to offshore, highlands and remote postcodes may take longer than the usual one working day. The surcharge may not apply to small items being sent via Royal mail or MyHermes etc... Where possible we will try our best to avoid courier service for surcharge areas. In 2016 I bought a Vauxhall Zafira diesel automatic, with a DPF filter fitted as standard. As I was driving the car from Southampton to Bristol the engine glow plug light began flashing. Different cars will illuminate different warning lights as you can see in the image below. Diesel particulate filters (DPF) are placed on the exhausts of diesel vehicles to prevent toxic emissions from flowing into the environment. Despite this, some motorists have the diesel filter removed to avoid mechanic failures and additional maintenance costs.

Campaigners are voicing complaints to the Advertising Standards Agency (ASA) regarding the spike in DPF filter removal. Such ads are deemed to be breaking the ASA code of conduct that condones practices that encourage anti-social behaviour. It’s alleged that such ads are exploiting a loophole in the law which clearly states that driving a diesel vehicle on the road without a DPF is an offence, but the actual removal of the filter is not. Update – October 2023– We have updated our product recommendations in line with some excellent new products that have been released in the UK market. In a press release from 2 May 2016, FOE air pollution campaigner, Oliver Hayes, stated, “Air pollution is a public health crisis of breath-taking proportions. The dodgy practice of removing pollution filters from cars is not only risking people’s health but also putting drivers at risk of prosecution for the simple fact that it’s illegal to drive a car with its DPF removed.” Since 2014, any diesel vehicle missing a diesel particulate filter will automatically fail its MOT. The Guardian newspaper revealed that thousands of drivers have been caught without a DPF fitted to their vehicles. 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.If you have an automatic select the auto second gear position and drive the engine around 5,000 rpm. If you only ever use your car for short journeys around town and never drive on a motorway, it’s recommended to use a DPF cleaner in every second or third tank of fuel, doing so will signifanctly reduce soot built up in the DPF. 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. Prior to the conception of DPF filters, those harmful exhaust gasses were being pumped straight out into the atmosphere.
