The particle filter is a quite modern invention that aims to remove harmful particles from the exhaust gases of modern diesels. It has long been discovered as the miracle solution to these pollution complications. Nevertheless, it doesn’t work as well as intended and causes more complications than it handles, which is why we will find out today when changing the particulate filter of a Porsche Cayenne? . To get this done, first of all, we will identify what the particle filter on your car is used for, and then when to change the particle filter on your Porsche Cayenne.

What’s the purpose of a Porsche Cayenne’s particulate filter?

So we start our guideline with the reason to do this component recently built in into diesel vehicles. As we described quickly in the introduction, the purpose of this filter was to solve the complications of pollution and harmfulness of exhaust gases from Porsche Cayenne vehicles. Its functioning 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 bring about a second combustion that will finish burning and get rid of all these carcinogenic particles. Regrettably, to reach this very high engine temperature, you have to be on the highway or have your Porsche Cayenne engine revving up. So we have discovered with time that cars that are specifically on short trips or in the city do not enable the particulate filter to burn these gases and we will see in the next part that these complications can force you to change the particulate filter of your Porsche Cayenne .

The second one, the one we are keen on today, works with precious metals that will produce a chemical reaction at high temperature and bring about the regeneration of the filter and the evacuation of the carcinogenic materials. Nevertheless, as described earlier, 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.

In spite of everything, the current particulate filter have not been well designed and remain troublesome, it is considered that as a result of the lack of a sufficiently regular temperature rise and other design complications, you should start 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 .
