Can you please show how to change for GL350, 2012. I am facing the same issue after the field measure, mercedes didn't change the feed line as it was not a part of it. So, I got CEL and need to replace ad blue feed line.
Great video instruction! Do you encounter the ADBlue pump failure issue and car throw out the code with adblue pump ground and short circuit? And also how do I inspect the injector? Thanks.

Would have been ncie to have more detail on running the new line, what a pain to do this job.
So what goes wrong with the existing line to generate fault codes. Can you see anything in live data to show the fault
It generates fault code P20B9, I believe, same for Adblue heater.

Any time I do electrical connections, especially underbody electrics, I clean the contacts and re-assemble with dielectric grease.
