The particle filter is a pretty modern invention that aims to take out harmful particles from the exhaust gases of modern diesels. It has long been discovered as the miracle solution to these pollution problems. However, it doesn’t work as well as designed and causes more problems than it handles, which is why we will discover today when changing the particulate filter of a Mercedes Classe E 4? . To get this done, to begin with, we will find out what the particle filter on your motor vehicle is intended for, and then when to change the particle filter on your Mercedes Classe E 4.

What’s the purpose of a Mercedes Classe E 4’s particulate filter?

So we start our guideline with the reason for this component not too long ago integrated into diesel vehicles. As we described briefly in the introduction, the aim of this filter was to solve the problems of pollution and harmfulness of exhaust fumes from Mercedes Classe E 4 vehicles. Its operating concept is to store exhaust fumes that are unburned or that still contain harmful particles, and when it is at a adequately high temperature to trigger a second combustion that will finish burning and get rid of all these carcinogenic particles. Unfortunately, to reach this very high engine unit temperature, you have to be on the highway or have your Mercedes Classe E 4 engine unit revving up. So we have discovered with time that vehicles that are specifically on short trips or in the city do not allow the particulate filter to burn these fumes and we will observe in the next section that these problems can force you to change the particulate filter of your Mercedes Classe E 4 .

When to change the particulate filter of a Mercedes Classe E 4?

In this section we will find out what you are certainly attracted to here, whether it is required to change the particulate filter of a Mercedes Classe E 4 and if so, when?

Is it required to change the particulate filter on Mercedes Classe E 4?

There are 2 kind of particulate filter for vehicles, a particulate filter with additive, which does not concern the Mercedes Classe E 4, but which needs to be recharged every 120, 000km with an additive that allows the regeneration of the particulate filter and consequently to burn all those harmful soot. The second one, the one we are interested in today, functions with precious metals that will generate a chemical reaction at high temperature and trigger the regeneration of the filter and the evacuation of the carcinogenic materials. However, as mentioned above, it needs very high temperatures, if these are not reached the filter will clog. If the filter is not regenerated manually, drive at high speed for about 20 minutes to reach this temperature and thus regenerate your filter, you will clog it and risk damaging your turbo, your EGR valve or your engine unit. If you need to clean the EGR valve of your Mercedes Classe E 4 as a result of your particulate filter, do not think twice to look at our content on this subject to find out what the process is.

This change should only be considered in the circumstance of a completely clogged particle filter. If you don’t frequently take the motorway, we suggest you, every month to drive 10 minutes on the motorway at least 3000 rpm . In spite of everything, the current particulate filter have not been well designed and remain problematic, it is considered that as a result of the lack of a sufficiently frequent temperature rise and other design problems, you should begin planning to change your particulate filter from 200, 000km if you have a use of your XX that is more urban and a little more if it is mixed .
