What is DPF reset?
Every filter, regardless of what it is designed to trap, will have to be cleaned and emptied on a regular basis so that there is space to continue trapping more things. This process of cleaning and emptying a Diesel Particulate Filter is called DPF regeneration.
Do Mercedes diesels have DPF problems?
Mercedes-Benz engines are picky when it comes to the oil they’ll accept. Diesels in particular are specifically designed with low-ash oil in mind. Needless to say, using oil with high ash content in particular can lead to DPF problems, as the higher ash content results in your DPF system getting clogged much sooner.
Do DPF cleaning additives work?
Sadly, for the most part, claims that an additive can unblock a dpf are largely exaggerated. In truth, these additives often produce a misrepresentation of what they are actually doing, and in reality, they never come close to unblocking a dpf filter.
Does DPF Cleaner Work?
Using Redex DPF Cleaner in every second or third tank will keep it working well. The soot burns away at high temperatures – so when you drive for a long time and a high speed your car can get hot enough to clear the filter. However, it’s not a very reliable way to keep the DPF working.
How do I know if my Mercedes has a DPF?
You can find the exhaust pipe between silencer and catalytic converter. In some car models, you will find DPF situated in the catalytic converter. You can check it by running your finger around the inside of the pipe. If it is relatively clean then you can assume that your car has DPF.
Does DPF clean itself?
During normal working condition the diesel particle filter will clean itself regularly by self-regeneration. After each regeneration-cycle, some ash are left in the filter and cause shorter regeneration interval. This means that each DPF will need service sooner or later.
