The particle filter is a fairly recent technology that is designed to remove harmful particles from the exhaust gases of modern diesels. It has long been seen as the miracle solution to these pollution problems. However, it doesn’t work as well as expected and causes more problems than it resolves, which is why we will discover today when changing the particulate filter of a Bmw Serie 5? . To do this, to begin with, we will find out what the particle filter on your motor vehicle is intended for, and then when to replace the particle filter on your Bmw Serie 5.

What’s the purpose of a Bmw Serie 5’s particulate filter?

So we begin our content with the explanation for this element recently integrated into diesel vehicles. As we described briefly in the introduction, the aim of this filter was to fix the problems of pollution and harmfulness of exhaust gases from Bmw Serie 5 vehicles. Its operating principle is to store exhaust gases 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. Unfortunately, to reach this very high engine unit temperature, you have to be on the highway or have your Bmw Serie 5 engine unit revving up. So we have noticed as time passes that cars that are mainly on short trips or in the city do not enable the particulate filter to burn these gases and we will discover in the next section that these problems can force you to replace the particulate filter of your Bmw Serie 5 .

There are 2 sort of particulate filter for cars, a particulate filter with additive, which does not matter the Bmw Serie 5, but which needs to be recharged every 120, 000km with an additive that enables 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 generate a chemical reaction at high temperature and bring about the regeneration of the filter and the evacuation of the carcinogenic materials. However, as revealed 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 Bmw Serie 5 as a result of your particulate filter, do not hesitate to check out our content page on this subject to find out what the procedure is.

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 regular temperature rise and other design problems, you should begin planning to replace 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 .
