Just spotted this while browsing around. It's a tiny archive regarding service work on a 400i by a USA company from earlier this year. On their FB page I also spotted some other updates regarding the whole upholstery on this 400. Not sure if this archive will be furhter updated though. At least nice to see another one being maintainted and preserved so well. So adding it here just for the records.
