Original wording in English

This informational bulletin provides information to dealership personnel on identifying Duramax Diesel overpower engine breakdown or non-function due to aftermarket power-up devices vs. non overpower engine non-function of pistons, cylinders, valve train components, and DTC P003A or P111D set.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
