Servus together. In the V50 forum nobody writes, but the D5 is also known here. V50 d5 model year 2009 Geartronic 139000 km My car is hissing from today to tomorrow. I went on troubleshooting and discovered a crack in the pressure tube. Pressure tube and a suspicious hose replaced. Car is still hissing. I guess the crack in the pressure tube has nothing to do with it, I discovered it because I was looking for the hissing. The rest of the charging pressure range is dense. In the area turbocharger / Kat/ DPF under low load already. (Someone gives some gas with brake and D and I listen) How does a dense DPF make itself noticeable? Especially since I have no error message and in Vida everything is also error-free. A regeneration by Vida was not finished after 35 minutes, which I then canceled. Soot loading but 0 grams. Do you have ideas? Hans
