    1 Fault Found:
    18689 - Terminal 30
    U140A 00 [008] - Open Circuit
    Terminal 30 is anything connected directly to battery positive. In short, something that should have constant battery voltage isn't getting voltage. Broken wire, poor terminal, popped fuse, ect. Even a failure within the control module itself can cause this type of fault code.

    I would look at your wiring diagram and see what fuses and terminal connections are involved for your J500 and verify they are all to factory design.

    Auto-Scan, learn it, love it, live it... then check the fuses.

    Could it possibly be related to the "03041 - Energy Management Active" code? The 18689 is new while I've been getting the 03041 fault for months. The car often sits in the garage for a week or more without being started and I get the "Low Battery" warning when turning on the ignition. The OEM battery is almost 4 years old and getting weak, I fear, even though the engine cranks and starts OK.

    Perhaps low battery voltage could trigger 18689?

    I doubt it. I would think you'd have have no voltage at all on Terminal 30 before you'd get an Open Circuit fault.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    This afternoon, I cleared the 18689 DTC and it didn't return when I rescanned. OK for now, I guess. I still have 5 months left on the Audi warranty just in case.

    Uwe & Jef, thanks for your help.
