stik87- Welcome to Autopia!
I have no idea whether this`ll work for you, but I`ve had great results just ignoring that the leather is "coated" and using the Leather Conditioners that the Conventional Wisdom says are ineffective on coated leather.
From an e36 M3, to my Tahoe, to the seats in my `93 Audi (and some others that weren`t as bad), the stuff that "shouldn`t work on coated leather" *did* work just fine. I figure it penetrated the pores/microfissures in the coating or something...whatever happened, things turned out great.
If you want to really do the job RIGHT, check out the offerings from Roger Koh, AKA The Leather Doctor (have to google him up, and he`s a bit of a PIA to order from). Processes like Fat Liquoring/etc. are apparently the *real* way to go for jobs like this (the Leatherique system is similar), but I`ve never bothered trying that stuff and don`t feel I`ve missed out. FWIW, I`ve used the other Leather Doctor products with great success.
OR just order some Leather Care Products from Griot`s Garage (IIRC they call theirs "Leather Rejvenator", it worked well for me) or from Leather Master or Sonus. All of those worked fine for me and are what I used on the three vehicles I mentioned above.
I`d just caution you to avoid products from Lexol (their Cleaner is OK, but not the rest of their line) and also Meguiar`s Gold Class (nasty mess of a product, I`ve had to clean it off a guys seats and I hate it).
