What does p0299 mean on a VW?
P0299 VOLKSWAGEN Meaning The Manifold Absolute Pressure (MAP) sensor measures the pressure inside the intake manifold. The pressure in the intake manifold is affected by turbocharging output, engine speed, accelerator pedal input, ambient air temperature, and Barometric Pressure (BARO).
Why do I get p0101 on my VW?
One common engine code Volkswagen owners get is P0101. Whether it is a gas or diesel, the cause is the mass air flow (MAF) sensor, which measures the amount of air flowing into the engine. The sensor is likely overly sensitive.

If the problem persistss the front oxygen (O2) sensor may need to be replaced. 2002 Volkswagen Passat
When does the intake manifold pressure go up?
Under normal operation, then the lowest pressure that can exist in the intake manifold is equal to the BARO. This occurs when the vehicle is operated at idle or when the ignition is ON while the engine is OFF. The highest manifold pressure occurs when the turbocharger output is high.
