 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
 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.

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).
Tip: 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).
