Component date codes relative to Fisher Body tag

date correctness · documented

Reference Details

Common issue
Date-coded components later than the Fisher Body tag date, or far outside the expected pre-assembly window, require car-specific documentation before being treated as original to a W46 car.
Confidence
documented
Correct value
Component date codes should fall within a few weeks before the Fisher Body tag assembly-date code; H/OCA describes the Fisher Body tag date as a three-character month/week code such as 11B.
Where to check
Compare component date codes on dated parts with the Fisher Body tag assembly-date code on the cowl/firewall.
