The particle filter is a pretty modern 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. However, it doesn’t work as well as expected and causes more complications than it handles, which is why we will find out in this article when changing the particulate filter of a Audi Sq5? .

The second one, the one we are keen on today, works with precious metals that will produce a chemical reaction at high temperature and cause the regeneration of the filter and the evacuation of the carcinogenic materials. However, as described earlier, it requires very high temperatures, if these are not reached the filter will clog.
