The particle filter is a quite recent 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 triggers more problems than it solves, which is why we will discover in this article when changing the particulate filter of a Opel Astra? .
