The particle filter is a pretty new technology that is designed 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 A class? . 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 A class.
What’s the point of a Mercedes A class’s particulate filter?
So we commence our content with the explanation to do this element not too long ago integrated into diesel automobiles. As we mentioned briefly in the introduction, the purpose of this filter was to fix the problems of pollution and harmfulness of exhaust fumes from Mercedes A class automobiles. Its functioning concept 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 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 A class engine unit revving up. So we have realized with time that vehicles 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 section that these problems can force you to change the particulate filter of your Mercedes A class .
When to change the particulate filter of a Mercedes A class?
In this section we will identify what you are clearly attracted to here, if it is necessary to change the particulate filter of a Mercedes A class and if so, when?
Is it necessary to change the particulate filter on Mercedes A class?
There are 2 types of particulate filter for vehicles, a particulate filter with additive, which does not matter the Mercedes A class, but which needs to be recharged every 120, 000km with an additive that enables the regeneration of the particulate filter and consequently to burn all those harmful soot. The second one, the one we are interested in today, works with precious metals that will create a chemical reaction at high temperature and bring about the regeneration of the filter and the evacuation of the carcinogenic materials. However, as explained earlier, it requires 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 A class because of your particulate filter, do not think twice to check out our article on this subject to identify what the procedure is.
When to change the particulate filter of a Mercedes A class?
As we defined before, a particulate filter is designed to last the life of the car, however some of you might wonder when it is necessary to change the particulate filter of its Mercedes A class? Take note that this part is extremely expensive, labor is not the most important issue because it is easy to access. But the component 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 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 troublesome, it is considered that because of the lack of a sufficiently frequent temperature rise and other design problems, you should start 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 .
