Had the same problem after 4 yrs on my 2000 CLK Cab. The interior is ash color. I purchased a new steering wheel from the dealer for about $300.00. Installed myself, it's easy..steering wheel removes by removing two hex bolts in the back body potion of the steering wheel (you need to fit the hex wrench deep into the two holes). I disconnected the battery prior..mechanic advised so that airbag wouldn't accidently deploy, not sure if true but did it anyway.
