Just got my GLK250, so bear with me.

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.

You have a panel in the rear that raises. The catch and handle is right in the center of the car very near the tail gate. The tank is in there also very near the centerline of the car.

The cargo floor of course raises and has a catch and handle as you describe. When raised, it exposes a lined storage area. No DEF addition nozzle apparent yet. The Adblue is no doubt below that storage area. Manual says that the storage floor can be slid forward. But it doesn't seem like it.

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.

Just slide/push the cargo floor forward and lift from the front end. It will come pretty easily out. At first I also thought it will be tight.

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

You may need to get the back side (nearest the seatbacks) free from the plastic trim panel first. Slide it slightly to the left and get it free, then it should slide towards the seatbacks and the front edge of the liner (near tailgate) should be free to lift out.

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.

Thanks guys.

I thing the part about moving cover to left is key. On the right it is under a metal? ledge.

I am sure I can now get it out without inflicting major damage
