Technical Bulletin
Service
Tip:
Refer to Elsa for other technical bulletins that may apply to specific vehicles with discharged batteries. These
technical bulletins provide important information about intermittent faults and correct battery testing/charging
procedures.
If charging system diagnosis for a fault/condition that is electrical in nature leads to the generator as the
suspected cause of the concern, it will be necessary to verify the failure of the generator by utilizing the applicable
Guided Fault Finding (GFF) Test Plan.
Only replace the generator if the GFF Test plan fails for this component. The completed failed GFF Test
plan must be uploaded to Volkswagen via GFF paperless or retained by the dealer (electronically or otherwise),
as it may be subject to request.
Note:
If the generator has failed in a manner that does not befit scan tool diagnosis (such as a bearing failure), ensure
that the reason for the replacement of the part is thoroughly documented in the repair order and warranty claim
comments.
Warranty
If a generator is replaced, there must be a confirmed failed GFF Test Plan available, or in the event of a
mechanical failure of the component, complete and detailed documentation of the reason for the replacement,
which must be submitted into the warranty claim comments.
If the Generator is requested to be returned to the Warranty Parts Return Center (WPRC) all documentation must
be included with the part return.
