Manufacturer summary

Original wording in English

This technical bulletin provides a procedure to replace the charge air cooler due to moisture getting inside of it and causing a malfunction indicator lamp illuminated with DTC P0300 and/or P0299/P2227.

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.
