The DMTL is super easy to replace. I didn't see any DIY on youtube so I made a really short video.

 

Thanks for taking the time to post this. And most importantly, for identifying a Bosh pump replacement.
To expand on your post a bit. (and for those who might not know ) DMTL is an acronym for
"Diagnostic Module for Fuel Tank Leakage" Essentially a pump that pressures the fuel tank based on intervals determined by the ECU.
The result of that pressurization determines whether an error code is displayed or not.

 

Appreciate the write up and especially the part number. Was actually looking at that section while I had the liners off last week. I'll save this for my records.
