The particle filter is a quite new technology that is designed to take out harmful particles from the exhaust gases of modern diesels. It has long been seen as the miracle solution to these pollution complications. Nevertheless, it doesn’t work as well as designed and triggers more complications than it handles, which is why we will discover today when changing the particulate filter of a Mercedes Classe E? . To do this, first of all, we will identify what the particle filter on your car is used for, and then when to change the particle filter on your Mercedes Classe E.
What’s the purpose of a Mercedes Classe E’s particulate filter?
So we begin our guideline with the explanation to do this component recently built in into diesel vehicles. As we mentioned briefly in the introduction, the intent of this filter was to resolve the complications of pollution and harmfulness of exhaust fumes from Mercedes Classe E vehicles. Its working principle is to store exhaust fumes that are unburned or that still contain harmful particles, and when it is at a sufficiently high temperature to bring about a second combustion that will finish burning and eliminate all these carcinogenic particles. Regrettably, to reach this very high engine temperature, you have to be on the highway or have your Mercedes Classe E engine revving up. So we have noticed as time passes that cars that are specifically on short trips or in the city do not enable the particulate filter to burn these fumes and we will see in the next part that these complications can force you to change the particulate filter of your Mercedes Classe E .
When to change the particulate filter of a Mercedes Classe E?
In this section we will identify what you are clearly drawn to here, if it is necessary to change the particulate filter of a Mercedes Classe E and if so, when?
Is it necessary to change the particulate filter on Mercedes Classe E?
There are 2 sort of particulate filter for cars, a particulate filter with additive, which does not matter the Mercedes Classe E, but which needs to be recharged every 120, 000km with an additive that allows the regeneration of the particulate filter and therefore to burn all those harmful soot. The second one, the one we are interested in today, works with precious metals that will produce a chemical reaction at high temperature and bring about the regeneration of the filter and the evacuation of the carcinogenic materials. Nevertheless, as described 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. If you need to clean the EGR valve of your Mercedes Classe E as a result of your particulate filter, do not think twice to look at our article on this subject to identify what the process is.
When to change the particulate filter of a Mercedes Classe E?
As we described just before, a particulate filter is designed to last the life of the vehicle, nevertheless some of you might wonder when it is necessary to change the particulate filter of its Mercedes Classe E? Take note that this part is extremely expensive, labor is not the main issue because it is easy to access. But the part itself will vary enormously in price based on your motorization, you can still count a range between 700 and 2000€. This change should only be considered in the circumstance of a completely clogged particle filter. If you don’t repeatedly take the motorway, we recommend 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 troublesome, it is considered that as a result of the lack of a sufficiently frequent temperature rise and other design complications, 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 .
