If, however, you can pinpoint the issue, a specialised engine cleaner will have insanely good results. Here are the common warning signs: 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.

Drivers who experience regular DPF problems due to their driving style should consider using a DPF Cleaner every couple of months or so depending on the frequency of their problem.STP® спонсорира своя собствен състезателен екип Indy Car, в който участва Марио Андрети, победител в Индианаполис 500.

What's the best diesel car ever?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. It’s mostly a cost saving exercise as filters easily become clogged up, especially with city driving where vehicles are driven at slow speeds in residential areas. 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.” If your running a turbo diesel engine and can feel a noticeable loss of power, there's a good chance the turbo could do with a cleanout**.**

Only a government could create this level of misery for our engines. Imagine if this were a human produce. You would be given the flu, which inhibits your ability to breathe, and a heart condition, preventing oxygen from reaching your heart and muscles. And then every time you exhale, it’s through a small straw. Try running a marathon like that… That’s what has happened to our automobiles with DPFs. The unmistakable clatter of a diesel engine is becoming a rarer sound nowadays. Demand for diesel is collapsing as politicians compare diesel pollution levels to that of the Chornobyl disaster. Even the white van man, who for years was fiercely defensive of the increased economy of diesel, is switching to hybrids or even to fully-electric offerings. I have been doing forced regens on my 2007 Skoda Octavia 170 Vrs quite frequently over the past 2 years since not doing anywhere near the mileage that I used to do having been made redundant and changing jobs. Walking to work and only running out at weekends now. Previously doing 100’s of miles each week. 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.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? Additives from reputable companies will normally do exactly what they say on the tin. They can’t fix mechanical faults, but can solve problems caused by deposits and contamination helping restore performance and efficiency. There are also products to help a tired engine through their final months and even extend their life, or products to get you out of trouble such as stopping leaks. No miracles, just honest technology that works. ‘Worth a try’ is something we often hear from converted sceptics.

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.

Liqui Moly claim it’ll dissolve hardened, dense and encrusted contaminants on the surface of diesel particulate filters ensuring optimum performance at all times. As well as restoring performance of the engine, crucially, it’ll also improve fuel consumption significantly. Liqui Moly have built up an excellent reputation for producing exemplary car care products and this DPF cleaner is arguably one of their most impressive products yet.

Cold Weather: In cold climates, diesel fuel can gel and cause problems in the fuel system. Some diesel additives include anti-gel properties to prevent fuel from gelling at low temperatures. My Dpf filter warning light comes off and I blast off down the dual carriageway for 20 mins at 3000 rpm …..that has worked until this week when dpf , glow plug and engine management lights all came on and went into limp mode. Biofuel Blends: If you’re using biodiesel or other biofuel blends, a diesel engine cleaner can help mitigate issues related to water and microbial growth in the fuel system. Like most filters, a DPF needs to be cleaned regularly otherwise it will become clogged and your DPF warning light may come on and could result in a trip to the mechanics! STP Diesel Particulate Filter is best used every 1800 miles as a preventative measure, however, should your DPF light come on, give it a try before you visit the mechanics.
