A GTI doesn't have a High Pressure Fuel Pump (HPFP) diesels do.
VAG Error Code: 18725
EOBD II Error Code: P2293
Fault Location:
Fuel Pressure Regulating Valve (N276) - Mechanical Malfunction
Possible Cause:
Malfunction Indicator Lamp (MIL)(K83) active.
Power Loss.
Fuel Pressure too Low.
Intake Camshaft Failure.
Possible Solutions:
Check Measuring Value Blocks (MVB) for Fuel Pressure.
Check for bent/squeezed Fuel Lines.
Check Fuel Pressure System for Leaks.
Check Fuel Filter & Filter in Fuel Pump.
Check Fuel Quantity supplied by the Fuel Pump.
Special Notes:
When found in
2.0l TFSI:
Check Fuel Pressure.
Rest of World (RoW) check Technical Product Information (TPI) 2014143, the Intake Camshaft might have a worn out Fuel Pump Cam.
North American Region (NAR) check Technical Service Bulletin (TSB) 2015153 (01-09-03 > 15-10-01 > 15-10-02), the Intake Camshaft might have a worn out Fuel Pump Cam.
North American Region (NAR) check Technical Service Bulletin (TSB) 2018183 (20-08-01) and verify the High Fuel Pressure Sensor (G247) Part Number.
Volkswagen Factory Service Bulletin OBDII Code P2293

Possible Cause:
Wiring/Connector(s).
Possible Solutions:
Check/Replace all faulty Wiring/Connector(s).
Read Measuring Value Blocks (MVB).
VAG Error Code: 18609
EOBD II Error Code: P2177
Fault Location:
System too Lean Off Idle, Bank 1 - Upper Limit Exceeded
Possible Cause:

Mass Air Flow (MAF) Sensor (G70) faulty.
Intake System leaking.
Exhaust System leaking.
Possible Solutions:
Check Mass Air Flow (MAF) Sensor (G70).
Check Fuel Pump (G6).
Check Fuel Injectors.
Check Intake System.
Check Exhaust System.
VAG Error Code: 16471
EOBD II Error Code: P0087
Fault Location:
Fuel Rail/System Pressure - Too Low
Possible Cause:
Power Loss.
Fuel pressure too low.
Fuel supply pipe blockage.
Fuel pressure sensor harness open circuit or shorted.
Fuel pressure sensor harness electrical circuit poor connection.
Blocked fuel filter.
Visual Inspection of Hardware (Camshaft, Cam Follower, etc).
Mechanical Deficiency of Hardware (worn or missing parts) .
Possible Solutions:
Check/Replace all faulty Wiring/Connector(s).
Check Measuring Value Blocks (MVB) for Fuel Pressure.
Fuel trim activity 0.90 - 1.15.
Output value rail pressure controller > 2 MPa.
Difference between target and actual pressure > -16.38 bar.
Check for bent/squeezed Fuel Lines.
Check Low Fuel Pressure System for Leaks.
Check Fuel Filter & Filter in Fuel Pump.
Check the Fuel Quantity supplied by the Fuel Pump.
Visual Inspection of Hardware (Camshaft, Cam Follower, etc).
Special Notes:
Petrol/Gasoline:
When found in
2.0l TFSI:
Check Fuel Pressure.
Check Technical Service Bulletin (TSB) 2027458/01-11-19 (VW North American Region (NAR)), for an improved Fuel Pressure Sensor (G410).
Check Technical Service Bulletin (TSB) 2015153/15-11-03 (VW North American Region (NAR)), for a worn Intake Cam Shaft (superseded Technical Service Bulletin (TSB) 15-10-02, 15-11-01 and 15-11-02).
Check Technical Product Information (TPI) 2014143 (VW Rest of World (RoW)), for a worn Intake Camshaft.
Check Technical Product Information (TPI) 2014909 (Audi Rest of World (RoW)), for a worn Intake Camshaft. This Technical Product Information (TPI) does NOT list in the Audi A6 (4F) BPJ Engine even though it is effected as well, so check for a worn Intake Camshaft of these too!
When found on 2009 Audi 3.2 FSI AVS Engines, if Diagnostic Trouble Code (DTC) 000022/P0016 is flagged, please see Technical Service Bulletin (TSB) 15-09-04.
Diesel:
When found on Common Rail TDI engines, please see Technical Service Bulletin (TSB) 01-10-11 (Technical Product Information (TPI) 2023624).
When found on Audi Common Rail V6, V8 and V12 TDI engines, please see Technical Product Information (TPI) 2020693. After mechanical all repairs are made Fuel Pressure Regulation Valve (N276) may need to be adapted and the EDC may need to be flash updated on the Audi Dealer level.
Tech Notes:
There is a service bulletin for the following Volkswagen vehicles:
Volkswagen Eos 2006-2007.
Volkswagen GTI 2006-2007.
Volkswagen Jetta 2005-2007.
