Service bulletin 122-Z3L6M-05

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Concern: Fault P0299 stored in the DME Information: Fault P0299 is stored when the actual boost level deviates from the specified boost level for greater than 3 seconds. Anything that can cause incorrect boost levels will set this fault, such as leaks in the intake/intercooler system, leaks in the boost control system (i.e. vacuum lines to the diverter valves, pressure converter and vacuum reservoir). All possible fault causes outlined in Guided Fault Finding MUST be addressed. If all of the possible causes are ruled out, then program the DME with PIWIS II software version 15.500 or higher. Some diagnostic hints: Check the freeze frame data of the fault. If the fault occurred at: <2500rpm/<60% engine load, this is most likely a software issue >2500rpm/>60% engine load, this is most likely a hardware issue (i.e. vacuum leak in a boost control line, or disconnected boost hose)
