    We do it because we are stupid ignorant noobies, and just do what the experts (see above) tell us (i.e., post the results of your Auto-Scan). In my particular field of endeavor, I'm not a noobie nor am I ignorant of the general expertise level, but here I am. Sorry you have to endure my ramblings.
    Still no posted auto-scan............

    Stop rambling post the scan......

    What is LDP condition of operation when running test 071 and or 0x01-03 Outputs?

    This code doesn't always mean there is a leak.......it means there could be and is most likely a wiring/power supply problem or issue with noid/reed on LDP or faulty controller.

    Using VCDS with the 071 test in conjunction with WD .....while observing block and DVOM would be a good idea.

    It is highly unlikely you would get an implausible signal from a leak in tank.

    Because there's a discrepancy between the text in VCDS and the text in the Wiki.

    The text in VCDS is a more literal translation of the original German, "Konzern-Datenbus Komfort im Eindraht" than the English text in the Wiki.

    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.

    Thank you so much for the actionable suggestion - I had no idea that the "passing" tests would provide additional info!

    In the P2404 error code, I see "Temperature: 91.5°C". Now this cannot possibly be the air temperature. I googled around for P2404, and see a bunch of other such freeze frames, and each one has a temperature of between 20 and 30 degrees C. Could my sensor be defective? Should I change it in any case?

    Nope .......not related.
    Stop the shot gun repair techniques.......

    Traditionally the LDP tests run when engine and intake temp are low, however,.......... in FSI and later CAN cars, it runs more frequent during throttle offset and under slight load.

    Continued tests in 071 during idle will historically result with small leak reported in cars after 2005>

    It would be a good idea to isolate the zones and do a crimp test to verify the consistency of the noids ability to hold the PSI...........( Advised )

    I looked in the Bentley manual and found the schematic with T17b and the EVAP pump on it (pages 2/12 and 2/13). I went to component locations, and looked at every section in vain to find a locator. Is this T17b - the circled connector? In any case I opened it up, the contacts are pristine. I see that D107 is the power bus going to the Purge Value as well as the EVAP pump, and that it is fused. I plan to check the fuse (when I figure out where it is), but wouldn't Auto-Scan pick that up?

    This car is garaged and in excellent condition.

    My wife (who drives the car) has reset this code many times using the "Automatic" app (and ODB widget). It normally triggers when she is driving around 30-40 MPH and many minutes after starting the car.

    Does that circled aforementioned connector look like it holds 17 terminals or wires?

    Time to RTFB the section called how to read WD in the manual.


    Get a tone generator and test from LDP up > Just follow the noise ......... Run a fast overlay.

    See if supply was faulty you would see DTC's for other BUS D107 items most likely.

    I would tests zones first for holding PSI generated by LDP before I went nuts with harness.

    Run the LDP manually with 071 and crimps in place to establish the hold or is it electrical!

    I'm in the same exact boat. I just had the evap-pump replaced and the CEL light remained off for about 30 miles.
    Not sure where to go next my VAG output is. Also readiness code went from 0000 to 0010.
    I do see a lot of notes about the J757 relay being the cause. I'm embarrassed to say I am unable to locate. (any hints)
    Don't mind taking to my mechanic,(who initially replace the Evap-pump) but relay seems something i could handle.
    And for the 13.00 it might be worth the shot. here is my output.
    Thank you guys..
