advice on leather transfer stain

[Cookies@xxxxxxx]

97' 840 ci. Light parchment interior. My wifes black leather coat tranferred
some black dye to the seats when the seat heaters were on and rain had fallen
on the coat. I have tried numerous cleaners.

Without having to extreme to re-dye, does anybody have any ideas to get this
shit off?? Really appreciate any magic formulas that won't take off the orig.
finish color
