S212 E350 Estate Seats in boot

[Seftonbarn]

I have just picked up a 2010 E350 Estate. It is the 7 seat version. The cup holder in the rear facing seats doesn't stay in it's housed position. Anyone know how I can remove to investigate?

To answer my own question. The leather seat can be pulled from the hard backing (it is held by spring clips). The Cup holder can then be removed from the backing board by 4 Torx screws. The cam assembly was broken. Proper fix would be complete assembly replacement but I managed to bodge a fix that appears to work.
