The particle filter is a quite modern technology 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 complications. However, it doesn’t work as well as designed and causes more complications than it handles, which is why we will discover on this page when changing the particulate filter of a Mercedes Slk? . To do this, first of all, we will identify what the particle filter on your motor vehicle is used for, and then when to replace the particle filter on your Mercedes Slk.

So we commence our content page with the reason to do this element not too long ago integrated into diesel vehicles. As we described quickly in the introduction, the intent of this filter was to solve the complications of pollution and harmfulness of exhaust fumes from Mercedes Slk vehicles. Its operating principle is to store exhaust fumes 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 Mercedes Slk engine unit revving up. So we have realized with time that vehicles that are specifically on short trips or in the city do not enable the particulate filter to burn these fumes and we will observe in the next section that these complications can force you to replace the particulate filter of your Mercedes Slk .

The second one, the one we are enthusiastic about today, works with precious metals that will produce 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 requires 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.
