Greetings friends of audisworld

After a greeting I need a help, I have a car audi a6 c6 3.2 liter quattro 2008 I have turned on the check engine light and I throw error, I share the image of the errors to see what I can say .



P.S. The car was subjected to change of the two cylinder head, It helps in low rpm the car shuts down after 5 seconds after turning it on.


I delete the error but in low RPM car shuts down after 5 seconds after turning it on.

This is my audi A6 C6 2008 Quattro

DTCs P2006 and P2007 are probably due to vacuum leak, most likely the plastic vacuum tube that runs down the front of the engine on the driver's side (supplies vacuum to the leak detection pump (LDP) in the EVAP system). These two DTCs won't cause the engine to stop, so the real problems are the other DTCs (P0172 and P0175), which could be caused by one of the following (from the Bentley Repair Manual):

Evaporative Emission System
(EVAP) Canister Purge Regulator Valve N80 , checking
Evaporative Emission (EVAP) canister system, checking for proper seal

Fuel System
Fuel Injectors , checking
Fuel pressure and residual pressure before high pressure pump, checking , checking
Fuel Pressure Sensor G247 , checking
Fuel Pump (FP), checking delivery quantity
Low Fuel Pressure Sensor G410 , checking

Heated Oxygen Sensors
Heated Oxygen Sensor (HO2S) before catalytic converter, checking
Heated Oxygen Sensor (HO2S) behind catalytic converter, checking
Oxygen Sensor (O2S) Heater for Heated Oxygen Sensor (HO2S) before catalytic converter, checking
Oxygen Sensor (O2S) Heater for Oxygen Sensor (O2S) Behind Three Way Catalytic Converter (TWC) , checking
