Manufacturer summary

Original wording in English

Turbo models only. This bulletin announces the availability of reprogramming files to optimize the ECM. These new files will address customer concerns of: ? Spark knock (ping) during high intake air temperature operation ? Surge on acceleration due to phantom knock detection ? Check Engine light illumination resulting from DTC P2270 and / or DTC P2270 and / or P0137 being stored in the ECM memory.

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.
