New type alternator, Part No. 911 603 120 04, with integrated regulator, is now installed instead of former version, Part No. 911 603 120 02, which used separate regulator. Regulator of new version, Part No. 911 603 913 01 is located on back of alternator and can be replaced separately. Threads on alternator shaft for installation of pulley have also been changed from M 16 x 1 to 17 x 1.5.
The hub extension (air guide) has been modified to provide an opening for the regulator. Battery charge indicator lamp is changed from 2 W to 4 W, and the DF wire was removed from engine wire harness.

These changes were effective with 1982 model production.
