Workshop findings: The following DTC is stored in the engine control module (ECM), J623 (address word 0001): • DTC P000000 with symptom code 33688. • Furthermore, no test plan is suggested in the Guided Fault Finding. Technical Background DTC P000000 with symptom 33688 indicates a possible malfunction of the mechanical coolant pump. Due to a deviation in the tester, no test plan is currently shown for this in ODIS. The mechanical coolant pump of the EA839 V6TFSI can be switched via a vacuum. More information on the switchable coolant pump can also be found in the Self-Study Program (SSP) 920173 - The Audi 3.0l V6 TFSI EA839 Engine. Page 1 of 5 © 2023 Audi of America, Inc.

Technical Service Bulletin Production Solution Not applicable. Service Please carry out the following steps for further diagnostics: 1. Check the cooling system for the correct coolant level in the coolant expansion tank: a. If the coolant level is correct, continue with Step 2. b. If the coolant level is not correct, check the cooling system for leaks. If a leak is found, replace the responsible component according to ELSA. If no leak can be found, but the coolant level is still not correct, top off the cooling system according to ELSA. Continue with Step 2. 2. Using the following table, check whether one of the software versions (or a newer or higher version) is already installed on the engine control unit of the vehicle: a. If an older software version (i.e. an older or lower version) is installed on the vehicle, then use the respective SVM code; if fault reoccurs after a scan continue with step 3. b. If one of the software versions (or a newer or higher version) listed in the table is already installed,continue directly with Step 3. In this case, a software update does not fix the customer concern.

Technical Service Bulletin 3. Check the operation of the vacuum control of the mechanical coolant pump: a. Check for vacuum (using VAS6213) at the output port of solenoid N649 which commands the water pump sleeve (Figures 1 and 2). The engine needs to be cold to generate a command signal to the N649 solenoid to switch to a vacuum. With the engine cold, start the engine briefly and monitor that vacuum is created. b. If there is no vacuum measured at the output port of N649, the cause of the fault could be related to the solenoid valve N649 or the vacuum hoses (check for leaks). In this case, repair and check the Figure 1. Checking the vacuum at the output port of N649. operation of the vacuum system. Page 3 of 5 © 2023 Audi of America, Inc. All rights reserved.

Technical Service Bulletin 4. If there are no malfunctions found in the vacuum system, check the operation of the water pump sleeve by applying a vacuum to the hose going to the water pump (hose connected to the output port of N649). When applying a vacuum to the pump, pay attention to the clicking sound of the water pump sleeve. If no clicking is heard or felt, replace the mechanical coolant pump. Figure 2. The output port of N649 (close-up picture). 5. If a leak is found in the cooling system, attach a photo of the concern to the repair order.
