^ Engine runs rough after cold start.
^ Excessive engine cranking time.
^ Hesitations while driving.
^ Rough engine idle.
^ Reduced engine performance.
^ Poor fuel economy.
Conditions may be severe enough to illuminate the MIL in conjunction with storage in the ECM data memory of DTCs for misfire (example: P0300,
P030x) and / or lean fuel system (example: P0171, P0174, P1128, P1130, P1136, P1138).

^ May contain undissolved water.
^ May contain sediments and suspended matter.
^ May appear cloudy and (after settling) may show signs of separation.
Repair:
Gasoline additive G 001 700 03 or G 001770 A2 can be used for removal of existing carbon deposits from:
^ MPI engine
^ Injectors.
^ Combustion chambers.
^ Intake valves.
^ FSI engine
^ Injectors.
^ Combustion chambers.
Tip: For removal of carbon deposits from intake valves of FSI engines, refer to TSB 2019948.
Mix the additive with gasoline directly in the full fuel tank following the mix ratio. For example, 60 ml per 30 liters gasoline, 150 ml per 20 gallons
of gasoline.
