I'm starting a new thread to make it easier to search this issue.
I recently experienced the following problems with my van. It's a Euro 6 102bhp 2017 model.
Basically my mpg started to decrease significantly and my adblue consumption started to go through the roof, for no good reason. Eventually the engine management light came on and I did a scan with VCDS.
