The particle filter is a quite new 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 causes more problems than it resolves, which is why we will find out in this article when changing the particulate filter of a Cadillac CTS? .

Its operating concept is to store exhaust fumes 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 eliminate all these carcinogenic particles. Unfortunately, to reach this very high engine unit temperature, you have to be on the highway or have your Cadillac CTS engine unit revving up.

The second one, the one we are keen on in this article, functions 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 explained above, 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.
