## NHTSA's summary

MIL on. Customer may report a reduction in power. DTC P029900 \(Turbo/Super Charger Underboost\) is stored in the engine control module \(ECM\), J623 \(address word 01\). The circlip connecting the turbo wastegate actuator rod and the wastegate flap lever can fall of due to low tension of the clip. Consequently, the wastegate linkage becomes disconnected, causing MIL on and DTC P029900.
