For those car owners that have more advanced skills under the bonnet, and for car workshops, Wynnís has launched a new Off-Car Diesel Particulate Filter (DPF) Cleaner. We have all heard the horror stories of expensive DPF failures and those that fail to regenerate, and so this solution cleans the filter and removes all of the deposits in as little as two hours. Itís designed for cars with the DPF light permanently on, which would normally need a visit to the dealer. Once youíve tried the bottled fuel tank treatments to get the deposits shifted and youíve had no luck, taking the DPF off the car and bathing it in the cleaner is your last chance of avoiding a hefty replacement bill. While specialist companies will be well versed in following a similar practice, Wynnís new cleaner gives keen, capable DIY motorists the chance of giving it a try themselves, with clear instructions to gain a successful filter clean. Itís not for the faint-hearted or the amateur mechanic, and make sure that you use gloves and safety glasses to avoid any accidents. Priced at £30 for a five-litre container, Wynnís Off-Car DPF Cleaner is available to buy now at Euro Car Parts and other good motor factors.
