PO440 Possible Causes:
Charcoal canister is loaded with fuel or moisture
Fuel filler cap is loose, cross-threaded, damaged or wrong part
Fuel tank, fuel filler neck or fuel sending unit 'O' ring is leaking
Fuel tank pressure sensor is damaged, disconnected or it failed
Fuel tank vapor line(s) is clogged, damaged or disconnected
Purge valve vapor line is clogged, damaged, or disconnected
Purge or vent solenoid power circuit is open (check the fuse)
PCM has failed
PO443:
Purge solenoid control circuit is open or shorted to ground

P0440 - Evaporative Emission (EVAP) System
evaporative emission (EVAP) system has a large leak.
Check the gas cap or vent valve. these are the most common problems.
The Powertrain Control Module (PCM) at different times performs various tests on the EVAP system. OBD II
Enhanced EVAP systems are in place to keep fuel tank vapors from
venting into the atmosphere, and instead purges them into the engine to
be burned. Regular pressure tests are conducted by the PCM to monitor
the sealed system for leaks. The PCM monitors the EVAP system pressure
by watching the Fuel tank pressure sensor (FTP). When the sensor
indicates a small leak in the EVAP system, this code is set.
Here are some additional causes.
* A small leak in any of the EVAP hoses or fuel tank hoses
* A small leak in the purge valve or vent valve
* The EVAP Canister may be leaking
SOURCE: Code PO 238 on 2001 VW Beetle where do i start
The P0238 code relates to a Turbo Boost sensor pressure High. The P0106 is a MAP sensor code and could be caused by a bad or loose hose to the MAP sensor and can cause the P0171 which is system to lean code. The P0297 is a vehicle overspeed code. Hope this helps you some.
