The particle filter is a pretty new technology that aims to take out 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 designed and causes more complications than it resolves, which is why we will see today when changing the particulate filter of a Lexus GS? . To do this, first of all, we will find out what the particle filter on your motor vehicle is utilized for, and then when to change the particle filter on your Lexus GS.
What’s the point of a Lexus GS’s particulate filter?
So we commence our article with the reason for this component not too long ago included into diesel automobiles. As we described briefly in the introduction, the purpose of this filter was to fix the complications of pollution and harmfulness of exhaust gases from Lexus GS automobiles. Its working 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. Sadly, to reach this very high engine unit temperature, you have to be on the highway or have your Lexus GS engine unit revving up. So we have realized with time that vehicles 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 complications can force you to change the particulate filter of your Lexus GS .
When to change the particulate filter of a Lexus GS?
In this section we will find out what you are clearly attracted to here, whether it is required to change the particulate filter of a Lexus GS and if so, when?
Is it required to change the particulate filter on Lexus GS?
There are 2 types of particulate filter for vehicles, a particulate filter with additive, which does not concern the Lexus GS, 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 interested in 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. Nevertheless, as mentioned 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 unit. If you need to clean the EGR valve of your Lexus GS because of your particulate filter, do not hesitate to look at our content page on this subject to find out what the procedure is.

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 circumstance of a completely clogged particle filter. If you don’t repeatedly 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 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 .
