Central Coding Code Labels
A label printed with the ZCS code was used as a back-up to the electronic version stored in the control modules. This back-up was necessary particularly on vehicles which had the ZCS stored in only one control module.
The ZCS label was eliminated from all vehicles except the 318ti and Z3 starting with late 3/98 production. The 318ti and Z3 had the labels eliminated as of 9/98 once the instrument clusters were linked to diagnosis.
The storage locations of the labels are as follows:
- E31/E32/E34: inside the fuse box cover.
- E36: up to 9/93 under the rear sear in the center. After 9/93 on the cover for the left side fuel sending unit.
- E38: inside the E-box cover.
- E39: in the right side of the trunk next to the battery.
