The use of contaminated gasoline or gasoline with a low content of deposit control additives may result in one or more of the following conditions:
- Excessive accumulation of deposits on intake valves, intake manifold, fuel injectors, and combustion chambers.
- Engine running rough after cold start.
- Excessive engine cranking time.
- Hesitations while driving.
- Rough engine idle.
- Reduced engine performance.
- Poor fuel economy.
Workshop findings:
Conditions may be severe enough to illuminate the MIL in conjunction with storage of DTCs in engine control module (ECM), J623 (address word 0001) for one or more of the following concerns:
- Misfires (example: DTC P0300 and P030x ).
- Lean fuel system (example: DTC P0171, P0174, P1128, P1130, P1136, and P1138 ).
- Air/fuel ratio imbalance (example: DTC P219C00, P219D00, P219E00, P219F00, P21A000 or P21A100 ).
TECHNICAL BACKGROUND 1
- Condition may be caused by use of contaminated gasoline.
- Condition may be caused by use of gasoline with a low content of deposit control additives.
For MY16-MY19 3.0TFSI EVO (CREC) equipped vehicles:
- Because of deviations in the country-specific fuel quality deposits can form in the injectors preventing their complete closure. After switching off the vehicle fuel can get into the lower intake manifold or cylinder which makes the mixture too rich for the subsequent start. Do not replace injectors for this issue.
PRODUCTION SOLUTION
Not applicable.
SERVICE
For MY16-MY19 3.0TFSI EVO (CREC) equipped vehicles, and If deposits in the injector is suspected:
Use the multi-purpose additive for gasoline according to the guidelines to remove any deposits on the low-, and high-pressure injector and to ensure their tight closure. Do not replace injectors for this issue. Use additive first then continue with further diagnosis if the issue persists.
If use of contaminated gasoline is suspected:
Consider advising the customer to change gasoline source (brand/gas station). Contaminated gasoline may exhibit one or more of the following characteristics:
- May have unique color and odor.
- May contain undissolved water.
- May contain sediments and suspended matter.
- May appear cloudy and (after settling) may show signs of separation.
If use of gasoline with a low content of deposit control additives is suspected:

Repair:
Gasoline additive G 001770A2 can be used for removal of existing carbon deposits from:
- Injectors (MPI and FSI engines).
- Combustion chambers (MPI and FSI engines).
- Intake valves (MPI engines only).
Mix the additive with gasoline directly in the full fuel tank following the mix ratio. For example, 60 ml per 20 liters gasoline or 120 ml per 10 gallons of gasoline.
For MY16-MY19 3.0TFSI EVO (CREC) equipped vehicles use additive G 001780M3 (200 ml).
For removal of carbon deposits from intake valves of FSI engines, refer to TSB 2019948: 01 MIL on (P0300 and/or P0301 - P0306 stored in ECM).
