This option code is a mystery in the context of the E38 7 series, because it was only seen on a handful of pre-production models produced between September 1993 and May 1994. This option code was later re-utilized as “Deleted, coolbox/bar compartment“, on L7s.
15 E38s were produced with this option code.
