The particle filter is a fairly recent invention that aims to take out harmful particles from the exhaust gases of latest diesels. It has long been seen as the miracle solution to these pollution problems. However, it doesn’t work as well as designed and causes more problems than it resolves, which is why we will see in this article when changing the particulate filter of a Renault Megane 3? . To get this done, first of all, we will identify what the particle filter on your car is utilized for, and then when to replace the particle filter on your Renault Megane 3.
What’s the purpose of a Renault Megane 3’s particulate filter?
So we start our article content with the reason to do this component not too long ago built in into diesel vehicles. As we mentioned briefly in the introduction, the goal of this filter was to solve the problems of pollution and harmfulness of exhaust fumes from Renault Megane 3 vehicles. Its functioning principle 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 eliminate all these carcinogenic particles. Sadly, to reach this very high engine unit temperature, you have to be on the highway or have your Renault Megane 3 engine unit revving up. So we have realized as time passes that cars that are principally on short trips or in the city do not allow the particulate filter to burn these fumes and we will see in the next part that these problems can force you to replace the particulate filter of your Renault Megane 3 .

The second one, the one we are enthusiastic about in this article, functions with precious metals that will produce a chemical reaction at high temperature and trigger the regeneration of the filter and the evacuation of the carcinogenic materials. However, as explained 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 unit.
