Supersedes Technical Service Bulletin Group 21 number 13-16 dated July 9, 2013. The MIL is on. DTC P029900 (Negative Pressure Deviation) is stored as a static fault in the engine control module (ECM), J623 (address word 01). Under certain driving conditions, the linkage for the waste gate actuation can encounter excessive wear which leads to play at the waste gate flap. This leads to boost escaping through a loose flap, which sets DTC P029900 (Negative Pressure Deviation).
