Purchase my 06 audi a4 last month and today my epc and my check light came on. Check it with a code reader and these 4 codes pop up on the reader. Would like to no if anyone has experience with this issue before taking it to the dealer for inspection.

P0243 - N75 Valve
P0444 - EVAP Purge Control Circuit No Signal
P2294 - Fuel Pressure Regulator Valve (N276)
P2400 - Evaporative Emission System Leak Detection Pump Control Circuit/Open
