The particle filter is a fairly recent invention that is designed to remove harmful particles from the exhaust gases of latest diesels. It has long been discovered as the miracle solution to these pollution complications. Nevertheless, it doesn’t work as well as expected and triggers more complications than it resolves, which is why we will find out on this page when changing the particulate filter of a Audi S4? . To do this, first of all, we will find out what the particle filter on your motor vehicle is intended for, and then when to change the particle filter on your Audi S4.
What’s the point of a Audi S4’s particulate filter?
So we commence our content page with the rationale for this component recently included into diesel vehicles. As we described briefly in the introduction, the aim of this filter was to solve the complications of pollution and harmfulness of exhaust fumes from Audi S4 vehicles. Its working principle is to store exhaust fumes 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 get rid of all these carcinogenic particles. Unfortunately, to reach this very high engine temperature, you have to be on the highway or have your Audi S4 engine revving up. So we have noticed over time that cars that are mainly on short trips or in the city do not allow the particulate filter to burn these fumes and we will observe in the next part that these complications can force you to change the particulate filter of your Audi S4 .
When to change the particulate filter of a Audi S4?
In this section we will find out what you are certainly attracted to here, if it is required to change the particulate filter of a Audi S4 and if so, when?
Is it required to change the particulate filter on Audi S4?
There are 2 types of particulate filter for cars, a particulate filter with additive, which does not concern the Audi S4, 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 enthusiastic about today, 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. Nevertheless, as explained 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. If you need to clean the EGR valve of your Audi S4 as a result of your particulate filter, do not hesitate to check out our content page on this subject to find out what the process is.

As we defined just before, a particulate filter is supposed to last the life of the car, nevertheless some of you may wonder when it is required to change the particulate filter of its Audi S4? Take note that this component is extremely expensive, labor is not the most important problem 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 case of a completely clogged particle filter. 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 as a result of the lack of a sufficiently frequent temperature rise and other design complications, you should begin 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 .
