I am reading my MB DTC as I type this:
W124
"Up to 03/86 (production date 643) no fault recognition integrated in KE control unit (N3)." Page 14 of Testing Electrical Components of the KE injection system.

Furthermore:
"Since 04/86 faulty input signals have been recognized by the KE control unit (N3) and passed on to the lambda test output. Fault recognition is performed with a lambda control tester (012) at the diagnostic socket (X11)." Page 15 of the document above.

"Recognition of control units:
70% with fault recognition
100% without fault recognition"

No mention of when the 85% for California started though.
