The particle filter is a quite 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 problems. Nevertheless, it doesn’t work as well as designed and triggers more problems than it solves, which is why we will find out on this page when changing the particulate filter of a Audi E-Tron? . 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 replace the particle filter on your Audi E-Tron.
What’s the point of a Audi E-Tron’s particulate filter?
So we commence our article content with the rationale to do this component recently included into diesel vehicles. As we outlined quickly in the introduction, the purpose of this filter was to fix the problems of pollution and harmfulness of exhaust gases from Audi E-Tron vehicles. Its working principle is to store exhaust gases that are unburned or that still contain harmful particles, and when it is at a adequately high temperature to cause a second combustion that will finish burning and eliminate all these carcinogenic particles. Unfortunately, to reach this very high engine temperature, you have to be on the highway or have your Audi E-Tron engine revving up. So we have discovered over time that cars that are specifically on short trips or in the city do not allow the particulate filter to burn these gases and we will observe in the next section that these problems can force you to replace the particulate filter of your Audi E-Tron .
When to replace the particulate filter of a Audi E-Tron?
In this section we will find out what you are certainly attracted to here, if it is necessary to replace the particulate filter of a Audi E-Tron and if so, when?
Is it necessary to replace the particulate filter on Audi E-Tron?
There are 2 kind of particulate filter for cars, a particulate filter with additive, which does not concern the Audi E-Tron, 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 keen on today, works with precious metals that will generate a chemical reaction at high temperature and cause the regeneration of the filter and the evacuation of the carcinogenic materials. Nevertheless, as mentioned earlier, 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. If you need to clean the EGR valve of your Audi E-Tron because of your particulate filter, do not hesitate to check out our article on this subject to find out what the procedure is.
When to replace the particulate filter of a Audi E-Tron?
As we explained before, a particulate filter is supposed to last the life of the vehicle, nevertheless some of you might wonder when it is necessary to replace the particulate filter of its Audi E-Tron? Be aware that this part is extremely expensive, labor is not the main issue because it is easy to access. But the part itself will vary enormously in price depending on your motorization, you can still count a range between 700 and 2000€. This replace should just 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 because 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 .
