I'm championing the Alpina D3 S (in green, obviously) and the utterly stupid but interesting Audi Q7 V12 TDI. Update – October 2023– We have updated our product recommendations in line with some excellent new products that have been released in the UK market. Deposits in the fuel system, air intake, EGR valve, injectors, etc. Modern diesel fuel systems are highly engineered, but are susceptible to deposits which may effect the efficiency of combustion. Inefficient combustion = more hydrocarbons, and therefore more soot in the exhaust and filter. Over the last 10 years, air pollution has become a public health emergency and it is further alleged that particulate pollution is now responsible for around 50,000 avoidable deaths every year in the UK. In this review, we look at the best DPF (Diesel Particulate Filter) cleaners on the market for your diesel vehicle and explain why they are so important. DPF filters are fitted as standard on all modern diesel vehicles and can cause extreme problems if not maintained properly, so therefore it’s really important to understand how they work and how best to avoid problems with some simple preventative maintenance.

Because DPF filters have limited size and capacity, they can only store a limited amount of exhaust soot. Once the system has reached it’s capacity threshold (usually around 80%), the vehicle will attempt to begin a process called “Regeneration” What Is A DPF Regeneration? STP® продукти започва да нараства и скоро STP® продуктите са налични в повече от 200 000 бензиностанции в САЩ.Our 3.0 Bmw X3 Diesel E83 recently started giving problems and the cause was the dreaded Dpf. I tried three different makes of additive in the fuel tank but to no avail. I also attempted a manual regen. but again to no avail. I therefore had several choices. SAVING ON AVERAGE" and "AVERAGE PRICE" are calculated as an overall average of prices and savings obtained on quotes on the same job type within the radius from which quotations are obtained. The DPF catches soot (carbon) and about every 2000-5000 miles the engine management system will try to remove this by burning it. This can only happen if the car is driven (different manufacturers have slightly different strategies) on a fastish road above about 40-50mph for about 20 mins. If you don’t do this then at some point the car becomes desperate for a regen and may try and get some carbon burnt at less than ideal conditions. If this does not happen then at some point there is too much carbon and it could damage the substrate if a regen was started. 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.

I will try and run more frequently in recommended driving mode with the addition of some Wynnes dpf cleaner which I can get at 50% discount. If, however, you can pinpoint the issue, a specialised engine cleaner will have insanely good results. Here are the common warning signs:Once you have run the car very hot for a sustained period pull over and immediately switch off the car. 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? 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. Part of Liqui Moly’s Pro Line of products, the German branded Liqui Moly DPF cleaner takes our top spot. 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. The key features of Liqui Moly Pro Line DPF cleaner are;
