Welcome to the forum. 
VAG Error Code: 16648
EOBD II Error Code: P0264
Fault Location:
Injector 2 (N31) - Circuit Low/Short Circuit to Earth
Possible Cause:
Malfunction Indicator Lamp (MIL)(K83) active.
Engine Misfire.
Engine Run Rough.
Low MPG.
Fuse(s).
Wiring/Connector(s) short to earth.
Injector 2 (N31).
Engine Control Module (ECM).
Tech Notes:
Clogged or partially clogged fuel injector can cause this code. Start by performing an injector flush before replacing the injector.
Description:
Code P0264 is triggered when the Engine Control Module (ECM) detects a low voltage in the Fuel Injector 2 Circuit. During normal conditions the Engine Control Module (ECM) turns the Fuel Injectors ON and OFF in the Fuel Injection System.
VAG Error Code: 16829
EOBD II Error Code: P0445
Fault Location:
Evaporative Emission (EVAP) Purge Solenoid (N80) - Short Circuit
Possible Cause:
Malfunction Indicator Lamp (MIL)(K83) active.
Wiring/Connector(s) short circuit.
Evaporative Emission (EVAP) Purge Solenoid (N80).
Engine Control Module (ECM).
When is the code detected?:
An excessively high voltage signal is sent to Engine Control Module (ECM) through the valve.
Description:
The Evaporative Emission (EVAP) System Canister Purge Volume Control Solenoid Valve controls flow rate of fuel vapour from the Evaporative Emission (EVAP) System canister. The opening of the vapour by-pass passage in the Evaporative Emission (EVAP) System canister purge volume control solenoid valve changes to control the flow rate. The Evaporative Emission (EVAP) System canister purge volume control solenoid valve repeats ON/OFF operation according to the signal sent from the Engine Control Module (ECM). The opening of the valve varies for optimum engine control. The optimum value stored in the Engine Control Module (ECM) is determined by considering various engine conditions. When the engine is operating, the flow rate of fuel vapour from the Evaporative Emission (EVAP) System canister is regulated as the air flow changes. The EVAP canister purge volume control solenoid valve uses a ON/OFF duty to control the flow rate of fuel vapour from the EVAP canister.
The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the Engine Control Module (ECM). The longer the ON pulse, the greater the amount of fuel vapour that will flow through the valve.
