Simple color restoration using leather dye specially formulated for this X5 (BMW "Black " is in reality a deep gray with a dash of brown).
1) clean the seat thoroughly with Simple Green
2) rub in dye with a lint-free rag, then wipe off excess with a slightly dampened rag.
3) let dry for 20 minutes, then repeat.
This project took 4 very light coats to restore color to the wear on the seat.
