emissions problems. Members of the DPF Doctor Network receive advanced training in this specialised field with ongoing resources via Darren’s training portal to deal with new technical challenges and problems as they come across them. Of course, not every workshop can be a DPF specialist but it’s well worth building a relationship with a local specialist such as a DPF Doctor where you can refer your customers, just as you might with electronics or automatic transmissions. “You can also introduce them to a range of professional maintenance additives, such as JLM, which they can use on a regular basis for preventative maintenance. Our trade bestsellers include the class leading JLM DPF Cleaner, and the DPF Clean and Flush system for when the DPF is genuinely blocked. Also, JLM’s DPF Regen Plus and their Emissions Reduction Treatment are excellent preventative treatments to help maintain low emissions and protect emissions components. The JLM range goes as far as offering a high-quality engine oil flush which is essential to help clean an engine with oil contaminated by particulates.” Simple David Kaiser, Head of Research and Development at the oil and additive specialist LIQUI MOLY observed: “LIQUI MOLY offers a simple and cost-effective way to clean the clogged DPF while it is still installed. The DPF Cleaning Kit saves the customer days of waiting and high costs for the otherwise necessary removal of the DPF and shipping to a company specialising in DPF cleaning, making it an excellent customer loyalty tool for the workshop. The garage can also offer Diesel Particulate Filter Protector from LIQUI MOLY to customers who predominantly drive short distances. This additive lowers the temperature required by the filter for regeneration.” David added: “Vehicles with DPFs require low-SAPS motor oils in order not to overburden the filter with ash. If a conventional oil were to be used in a car with a DPF, the filter would clog prematurely and would have to be replaced. Filling in the wrong oil is an embarrassing mistake for any workshop and can result in expensive claims. You are on the safe side with a look at LIQUI MOLY’s free oil guide. All you have to do is enter the number plate of the vehicle and you will see a list of suitable oils.” To access the LIQUI MOLY free oil guide, visit: www.liqui- moly.com 40 AFTERMARKET OCTOBER 2022 EXHAUST SYSTEM AND DPF www.aftermarketonline.net Continuing increase Commenting on the growth in demand for DPF cleaning Ivor Searle has been seeing, Commercial Director David Eszenyi said: “In terms of the current market, we are seeing a continuing increase in demand for our professional DPF cleaning service for both diesel passenger cars and LCV applications. There are a number of drivers behind this demand including the growing number of ageing Euro 6 vehicles on the road that require effective DPF cleaning to ensure their exhaust emissions are compliant. Ongoing new vehicle supply problems are also forcing both private motorists and commercial users to keep their cars and vans on the road for longer, resulting in more blocked DPFs that need to be properly cleaned.“ Greater understanding With a view to helping technicians fit the correct parts when dealing with exhaust systems, and thereby help the industry play its part in helping reduce emissions, BM Catalysts is providing free downloadable technical posters, as well as a new animated video detailing the process of how a catalytic converter works. BM Catalysts Managing Director Toby Massey said: “BM Catalysts understands that the cataloguing of aftermarket parts can be complex, and that many consumers remain unaware of the Euro level of their vehicle. As some catalytic converters and DPFs may look physically identical to one another, the aftermarket needs to be aware of this information, as they can be very different in terms of what they are legally approved to fit. The message is loud and clear from the authorities that manufacturers, parts distributors and garages have an important role to play in ensuring the products they supply and fit are legal. Ignorance is not an excuse, and the market needs to be properly educated on areas such as Type Approval in order for it to remain compliant. Poor quality catalytic converters can still pass an MOT and mistakes can happen through the entire supply chain. Legislatively, it is very complex and this brings about exploitation of the rules and unfair competitive advantages. The regulators also need greater powers to have illegal items removed. It’s a growing problem and so greater enforcement, combined with greater communication and co-operation, will help raise standards, assist the market and deter others from breaking the rules.” Toby added: “BM Catalysts is working with distributors and workshops to ensure the automotive aftermarket Above: Using the Diesel Particulate Filter Protector Below: Darren Darling diagnosing DPF issues
