Adding DEF to GLK
I read the manual and it shows the Adblue filler at the LH back corner of the cargo area. I see nothing there. So, I presume the bottom covering of the storage space under the cargo area needs to be removed. Manual says to just slide it forward. Maybe I am missing something but that didn't seem to work.


I pried the front of the floor up and raised it enough to look back in. I found that the filler is at the back left hand (driver's side) corner. But not yet accessible.
What my concern was/is, is how to remove the complete storage floor without wrecking it. Looks like there could've/should'v been an opening in floor above the filler so the whole floor didn't have to come out.

edit. If you have Operator's Manual, see page 314.

It's not too bad, once you get the combination right!
The first cap (blue) just isolates the body from the DEF tank filler neck. There is another filler cap on the tank itself.
