Hello! I’m a bit desperate now, because I can’t get it out and it plays a role in buying oil. In the manual it’s an OPF mentioned, but not if my specific vehicle has one. Also in the Haynes manual I can’t find anything. I was under it today because I thought I got certainty. -> see pictures After the cracker comes a lambda probe, then apparently the cat (senkrechte built-in), another lambda probe, flex tube and then a short round cylinder, then the lan Is the short round cylinder of the particle filters? Unfortunately, the label is not clear regarding 5 or 8 or 9 – don’t find a specific part to the numbers that looks the same. If I enter the vehicle at kfzteile24.de, exhaust systems are offered without this part 🙁 Do you have a reliable information particle filters or not? — VW up! 3 Zyl, 44kW / 60 HP, 999cm3 Engine ID CHYE First registration 2020-Feb-24
