Technical Background In vehicles produced during a certain period, the AdBlue filter seal within the level sensor module may have been damaged during the assembly process or the AdBlue filter housing may come loose over time. This can allow unfiltered AdBlue to be drawn into the delivery system, subsequently damaging the pressure sensor and reducing agent pump V437. Production Solution Vehicle out of production. Service solution is an improved level sensor module. Service 1. In cases with the above fault codes, remove the active tank according to instructions in the Elsa Repair Manual. 2. Remove the G684 Reducing Agent Tank level sensor. 3. Inspect the reducing agent filter housing which should be clipped to the G684 level sensor module. If the filter housing is loose (see Figure 1 and Figure 2), then the G684 level sensor AND the V437 reducing agent pump must be replaced. Figure 1. Filter element housing loose inside tank.

Figure 2. Filter element housing loose inside tank. 4. If the filter is properly secured and only the P20E900 fault is present, clear the DTC and perform an SCR Metering Quantity Test to ensure the lines are purged of air. Do not replace any parts. Note: See Reduction agent injector testing – UDS video on the Audi Academy website for more information on how to access the SCR Metering Quantity Test. It is found under Basic Settings. Note: If the vehicle returns with the P20FE fault after the DTC has been cleared and the lines have been purged (assuming filter is secure), please contact the Technical Assistance Center (TAC) for further instructions. 5. Top off AdBlue level when repairs are complete. Page 3 of 5 © 2018 Audi of America, Inc. All rights reserved.
