you must be discconect 2 temp sens and dif sensor?you out ?

[Johnwick88]

The P0299 DTC code refers to a condition where the PCM/ECM (powertrain/engine control module) has detected that the bank "A" or single turbocharger or supercharger is not providing a normal amount of boost (pressure). That could be due to a variety of reasons, which we detail below. On a normally operating turbocharged or supercharged engine the air going into the engine is pressurized and that's part of what makes so much power for an engine of it's size. If this code is set, you will likely notice reduced power output. Turbochargers are driven from the exhaust exiting the engine to use a turbine to force air into the intake. Superchargers are mounted on the intake side of the engine and are typically belt driven to force more air into the intake, with no connection to the exhaust.
In the case of VW & Audi vehicles, the code definition is slightly different, it is "Boost Pressure Regulation: Control Range Not Reached." As you can probably tell that's basically just another way of stating an underboost condition.

It was better way to force dpf regeneration and drive car . Now when you put original file is car showing old DTC or new DTC ?
