Hello Zacko I just wanted to tell you that you saved me so much headache! I had this exact issue on my Passat B8. I recently had a temperature sensor changed (which was another whole headache as it was underneath the turbo so had to take it to a mechanic) and then after I got it back started getting the same issue when regenerating DPF. Did some research on the internet and was getting nowhere until I stumbled across your post! I compared my pictures from before the sensor changed and after and they were exactly like yours! So I pulled out the trusty 19" spanner and did a quick switcheroo. Thank you so much. I made an account just so I could reply to you. Have a great day man.
