Reading the comments here and the main article above, a lot of the statements made are in my experience, are incorrect regarding DPF cleaning additives. My Zafira was in excellent condition and may have been previously owned by a very careful driver that rarely revved the engine. 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. 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.
