The particle filter is a fairly recent invention that is designed to take out harmful particles from the exhaust gases of latest diesels. It has long been seen as the miracle solution to these pollution complications. However, it doesn’t work as well as designed and causes more complications than it handles, which is why we will see on this page when changing the particulate filter of a BMW 2 Series? . To achieve this, first of all, we will identify what the particle filter on your motor vehicle is used for, and then when to replace the particle filter on your BMW 2 Series.
What’s the purpose of a BMW 2 Series’s particulate filter?
So we commence our guideline with the rationale to do this component recently integrated into diesel vehicles. As we mentioned briefly in the introduction, the purpose of this filter was to resolve the complications of pollution and harmfulness of exhaust gases from BMW 2 Series vehicles. Its working concept is to store exhaust gases that are unburned or that still contain harmful particles, and when it is at a sufficiently high temperature to trigger 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 BMW 2 Series engine revving up. So we have realized with time that cars that are mainly on short trips or in the city do not allow the particulate filter to burn these gases and we will observe in the next part that these complications can force you to replace the particulate filter of your BMW 2 Series .
When to replace the particulate filter of a BMW 2 Series?

There are 2 types of particulate filter for cars, a particulate filter with additive, which does not matter the BMW 2 Series, 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 keen on in this article, functions with precious metals that will create a chemical reaction at high temperature and trigger the regeneration of the filter and the evacuation of the carcinogenic materials. However, as revealed above, 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. If you need to clean the EGR valve of your BMW 2 Series because of your particulate filter, do not hesitate to look at our content on this subject to identify what the process is.

In spite of everything, the current particulate filter have not been well designed and remain problematic, it is considered that because of the lack of a sufficiently frequent temperature rise and other design complications, 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 .
