    Did you know you can use VCDS to teach yourself using VCDS blocks & how to back trace by unplugging sensor on rail and observation of DTC/blocks to reflect the value if you believe a caption isn't documented, now did you read VCDS captions?

    I did not, I'm still learning my way around parts of the program, and am a novice with it. Did the log I post show anything of significance? Other than the engine speed, I do not know what the values of those fields are supposed to be.

    Read the blocks and captions in VCDS and you tell me?

    I see pressures and RPM of something in that log what blocks are they identified as in VCDS captions?

    Group 28 shows: engine RPM, ignition timing, *empty block*, and pressure (of what? Hpfp maybe?)

    Group 40 shows: engine RPM, load (of what?), Lambda, Lambda

    Hovering the mouse over each block does not show any captions. In some groups it does, but for whatever reason it is not doing so here, so I am unable to interpret what the values mean and what the specified range is. The manual talks about label files, but I am unable to read them when they are opened since they're encrypted

    Groups 028 and 040 were never documented by VW as far as I can tell.

    Fuel pressure should be in 020 and/or 021.

    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.

    Thanks Uwe. Both those channels show the same data, I logged both of them.

    Based on the captions in VCDS, everything looks normal except "High Fuel Pressure (specified), in group 20, "High Fuel Pressure (specified)" shows it should have a range of 250-300 bar at idle, while in group 21 it shows that it should read 220-330 bar at idle. The log shows it settles at 336 bar. a minute or two later after the logging stopped it went to 328 bar. I'm not sure what that is linked to. Here is the log:

    ALSO, after this, I ran an errand, when I came back the glow plug light was blinking again and it returned the same P0638 code. The car drove fine. I have no idea why the glow plug light comes on for things that have nothing to do with the glow plugs. I did an autoscan:

    So, my guess is that the Anti shudder valve (or throttle valve) could be faulty. I'm still not sure why the car suddenly was so difficult to start after I cleaned it, and since then has started and ran just fine. Also not sure if the slightly high fuel pressure is a concern.

    Given the weird 00003 error code that neither I or you were able to figure out in a previous thread, is it possible there is an electrical issue? I checked the grounding point next to the battery and it was fine. I don't know if there are other grounds to look for, or if this is even worth pursuing.

    A couple other points in case they are relevant - when I tested the battery with a multimeter, it showed 12.5v with the car off, and 13.8v with the car running, which seems good. Also, the resistance of the glow plugs seemed good (one plug showed 1.1 ohms, the other three were at .8 ohms

    Dont you think if you fix this or wiring problems it would be a good start?

    Most important question, isn't this repair under warranty extension and free or even under useful life warranty?

    The first suggestion, from what I read, was to clean it, which I did a few days ago, as I mentioned in my first post. The code stayed away for a few days until this evening. On your suggestion, I looked at the wiring from the glow plug harness and it showed no wear. I have not yet traced the wiring from the ASV and when I looked at it over the weekend I could not see where it went to.

    And yes, I assume the the ASV would be covered under the dieselgate warranty but I dont know for sure. I decided it would be easier to try cleaning it first then making a dealer appointment if needed.

    On the other hand, I'm at least learning a few things here, getting practice with VCDS, and familiarizing myself with a new-to-me engine.

    Isn't practically anything that would cause an MIL under such a warranty now that would make a vehicle fail SMOG?

    If the Flap can't operate than EGR would suffer function, don't you just love the vicarious nature of all this?

    Did you know your time spent and purchase of VCDS is reimbursable under useful life warranty?

    Did you read the entire JPPSG yet, the whole thread?

    Perhaps, but whats the harm in trying to clean it out if its a potential easy fix?

    Not sure how it is "vicarious"

    Did you know your time spent and purchase of VCDS is reimbursable under useful life warranty?
    "useful life warranty". First time I heard that term.

    Did you read the entire JPPSG yet, the whole thread?
    Yup
