The particle filter is a quite new invention that aims 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. However, it doesn’t work as well as intended and triggers more complications than it solves, which is why we will see on this page when changing the particulate filter of a Renault Megane 2? . To do this, first of all, we will find out what the particle filter on your car is used for, and then when to replace the particle filter on your Renault Megane 2.
What’s the purpose of a Renault Megane 2’s particulate filter?
So we commence our guideline with the rationale to do this element not too long ago included 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 fumes from Renault Megane 2 vehicles. Its working 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 cause 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 Renault Megane 2 engine unit revving up. So we have discovered with time 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 section that these complications can force you to replace the particulate filter of your Renault Megane 2 .
When to replace the particulate filter of a Renault Megane 2?
In this section we will find out what you are most definitely drawn to here, whether it is required to replace the particulate filter of a Renault Megane 2 and if so, when?
Is it required to replace the particulate filter on Renault Megane 2?
There are 2 types of particulate filter for cars, a particulate filter with additive, which does not concern the Renault Megane 2, but which needs to be recharged every 120, 000km with an additive that allows the regeneration of the particulate filter and consequently to burn all those harmful soot. The second one, the one we are enthusiastic about today, works with precious metals that will create a chemical reaction at high temperature and cause the regeneration of the filter and the evacuation of the carcinogenic materials. However, as described above, it necessitates 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 Renault Megane 2 due to your particulate filter, do not hesitate to look at our content on this subject to find out what the procedure is.

If you don’t frequently take the motorway, we advise 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 problematic, it is considered that due to the lack of a sufficiently regular temperature rise and other design complications, you should start 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 .
