2000/2001 Europa G500 Seat removal and disassembly. I remove the seat from my truck and then disassemble the seat base, remove the cushion and leather seat cover.
Mine was just the four bolts that held the seat rails to the base. If I recall, I had to de-pin the wire harness in the storage area below the seat because the connector was larger than the hole. In my seat the lumbar air pump is in the seat so there is no air hose. My truck is a MY2000, so if you've got an MBUSA version it could be completely different.
