Peugeot 407 AGR Ventil ausbauen und reinigen

The Peugeot 407 2.0 HDI jerks slightly when driving and when accelerating a black cloud comes out of the exhaust. The air flow meter and particulate filter were changed, but the problem persisted. Now I will remove and clean the EGR valve. Over time, the exhaust gas recirculation valve becomes stuck with soot and no longer works properly. So I'm going to expand and clean this here today. Let's see if it helps. It can be done with the standard tool;)
