The particle filter is a pretty recent technology that is designed to take out harmful particles from the exhaust gases of latest diesels. It has long been discovered as the miracle solution to these pollution problems. However, it doesn’t work as well as intended and triggers more problems than it resolves, which is why we will discover today when changing the particulate filter of a Subaru Crosstrek? . To achieve this, to begin with, we will find out what the particle filter on your car is utilized for, and then when to replace the particle filter on your Subaru Crosstrek.


What’s the purpose of a Subaru Crosstrek’s particulate filter?

So we commence our content page with the explanation to do this element recently integrated into diesel vehicles. As we mentioned briefly in the introduction, the purpose of this filter was to fix the problems of pollution and harmfulness of exhaust gases from Subaru Crosstrek 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 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 Subaru Crosstrek engine revving up. So we have noticed as time passes that cars that are mainly on short trips or in the city do not enable the particulate filter to burn these gases and we will discover in the next part that these problems can force you to replace the particulate filter of your Subaru Crosstrek .

When to replace the particulate filter of a Subaru Crosstrek?

In this section we will find out what you are clearly attracted to here, if it is necessary to replace the particulate filter of a Subaru Crosstrek and if so, when?

Is it necessary to replace the particulate filter on Subaru Crosstrek?

There are 2 types of particulate filter for cars, a particulate filter with additive, which does not matter the Subaru Crosstrek, 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 in this article, works with precious metals that will generate a chemical reaction at high temperature and trigger the regeneration of the filter and the evacuation of the carcinogenic materials. However, 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. If you need to clean the EGR valve of your Subaru Crosstrek because of your particulate filter, do not hesitate to look at our content page on this subject to find out what the procedure is.

When to replace the particulate filter of a Subaru Crosstrek?

As we described just before, a particulate filter is designed to last the life of the car, however some of you may possibly wonder when it is necessary to replace the particulate filter of its Subaru Crosstrek? Be aware that this component is extremely expensive, labor is not the main 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 replace should only be considered in the case of a completely clogged particle filter. If you don’t regularly take the motorway, we recommend 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 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 .
