Vehicle Information
Condition
BOTH of the following apply:
^ MIL on, DTC P0299 (Negative Pressure Deviation) is stored.
^ Turbocharger waste gate flap has play.
Technical Background
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 P0299 (Negative Pressure Deviation).
Production Solution
Not applicable.
