Purpose of Diesel Particulate Filter (DPF) cleaning?
To prevent DPF from getting blocked or choked due to excessive build up of soot or ash. This happens when the vehicle does not run enough time for the exhaust to reach the required temperature for burn off. This will result in performance losses or engine fault codes. Hence, it is advised to regularly maintain and clean your DPF as it is the cheaper alternative as compared to replacing an entirely new DPF.
