we had a few different issues with this model . the repair will be one of the following.

  • if the latch opens and does not move and then the door pulls closed again that can be fixed by reprogramming the tailgate lift control unit.
  • if the tailgate unlatches but does not raise at all it can be the liftgate module and or the hydraulic pump . the connections at the pump can corrode.
  • if the latch unlatches and the door starts to move up a few feet and then lowers it can also be the hydraulic pump as it can be getting weak.

this does not sound like a latch issue but more of a coding issue.

only the dealer or a european shop that has mercedes benz capable scanners.

hope this helps.

if you need more information please let me know and I will do what I can to help.
