What does this code mean?
The pressure signal or its relationship to expected engine conditions fails a range/performance check. Manufacturer implementations can compare multiple pressure signals or a calculated model; a universal voltage threshold cannot be inferred. The cited Volkswagen case concerns overly sensitive software, so P0106 alone does not establish a bad MAP sensor.
Sources and interpretation [1]
A code identifies a detected condition, not a part that must automatically be replaced.
Before replacing a part
Identify the engine and ECM software version before applying a bulletin. Follow that vehicle's pressure-signal plausibility test. Volkswagen 01 14 23 specifically calls for the applicable software update before replacing a MAP sensor or throttle valve for this concern.

Can I keep driving?
A code alone cannot establish whether driving is safe. A flashing malfunction light, severe shaking, overheating, oil-pressure warning or loss of braking or steering needs prompt attention. Stop in a safe place and seek assistance when control or engine safety is affected. Follow the vehicle handbook.
