    Post OBD2 0x33 MODE 9 please..........?

    Also post this.

    Thank you

    Firmware looks up to date at 0060 but I'm wondering if the thing is tuned...........?

    Continue to compile.........

    Ground wires for every coil pack must be overlay-ed & with a sufficient bus to carry ground back to battery directly!

    Thanks, Jack!

    Not sure I'm using the OBDII function correctly, but I've done my best to do as you directed. I don't have a controller at address 0x33 and am not sure how to perform OBDII functions on a specific controller, anyway. But going through the generic OBDII function on the main menu, then mode 9, yields the following data (shown as a picture as the "copy" and "save" functions are not functioning in the Mode 9 screen). Seems like VCDS is still working on something after producing this data (it says "running....", but no amount of waiting yielded more data). Let me know if you need more.




    Both 0x01-10-091 and 0x11-10-091 have a value of 4.

    How can I find out if it is tuned or not?

    Not sure how to take action on your statement regarding grounds for the coil packs. Please advise.

    Many thanks!

    Hey, morning.

    On a new tablet so this might be SCREWED UP.

    Noted last file of page 2, voltages falling, is that a new issue or may be testing a bunch, now it is low, can bite you, make sure charge it if so, been there done that.

    Not wanting to sound dumb but noticed MBAR, staying at 980 regardless of RPM, if this is baro, my bad, but if manifold pressure it is not moving. Any way came in late an not used to this tablet, so if I sound stoned, I'm not, good luck.

    Crimp tests can be done with needle nose vise grips using caution or smooth jaw pinch clamp pliers.

    Rubber plugs/wedges can also be used to isolate the intake lines from booster and N80 etc... & to focus on the bank or just intake area.

    Thanks, Larry! You're right on the voltage. I've been trying to stay on top of that using a charger, jumper cabling in a second battery, or both. Just one more thing I don't want to deal with. Thanks for pointing that out! Would definitely be bad if I missed that.

    Not sure on the MBAR being constant. Anyone else - is that an issue or as it should be?

    Crimp tests can be done with needle nose vise grips using caution or smooth jaw pinch clamp pliers.

    Rubber plugs/wedges can also be used to isolate the intake lines from booster and N80 etc... & to focus on the bank or just intake area.
    Thanks, Jack. Will work on this later this evening.

    So, my current list of activities to perform:
    A. Check compression on all cylinders
    B. Visually inspect ECUs for marked part number
    C. Check fuses/battery connections in general
    D. Do crimp tests to isolate vacuum leak
    E. Measure crankcase vacuum via modified oil cap (should have the tools and the extra oil cap necessary to complete this later this week)

    Outstanding questions I have:
    1. What is "PR-Build data" requested in JPPSG? I believe, scattered in this thread, I have provided the rest of the requisite data.
    2. Please let me know what else I need to do to complete JPPSG procedure.
    3. Further feedback on fuel injectors and if replacing them with brand new OEM is still necessary. Have been searching (instead of working) and have found OEMs for $100 each, which seems like a good deal... Again, I will do this if you feel it is necessary, just want to make sure.
    4. Clarify what action I need to take on grounding the coil packs. I have sourced a suitable bus bar to use in cleanly providing an aftermarket ground for each coil pack direct to battery but want to confirm before I dive into that. I wasn't sure if your statement was general knowledge or a direction to be followed.
    5. Is a fresh auto-scan, after clearing all current DTCs, still desired?

    Thanks!

    Oh yes, and this sums up how I feel things have gone...my son found this and I found it quite funny...

    I advise it.........can't trust reman injectors for a Gasser.

    Always with a fresh battery too!

    Thank you! And thanks for the rest of the above feedback.

    At risk of asking a dumb question...I see your FOD statement all over the forum and want to clarify...what are you talking about? There is nothing loose or broken in my engine bay (or vehicle, for that matter) that could be FOD in the aviation sense. And then there's the "make the car stock"...so you want me to remove...the exhaust, IM spacers and...anything else not OEM? I'm hoping that we can at least get it back to pre-teardown condition with the most physically extensive mods still in place...especially since I don't have a spare exhaust setup lying around...

    Do you know what gauge the current coil pack wiring is, or do you have a recommendation of what it should be? I'd like to get supplies before I tear down the plastic conduits that hold the wires everywhere that's readily accessible or the shielding at the back of the engine bay.

    The results of the compression tests are:
    1 - 124psi
    2 - 124psi
    3 - 124psi
    4 - 125psi
    5 - 123psi
    6 - 123psi
    7 - 123psi
    8 - 126psi

    Why are the back two cylinders slightly higher than the rest of the respective bank? Is that `normal?

    The one ECU I can easily see (under the windshield cowling) is most definitely not original - it has a date of 6-11-2009...


    Idiot question, but where is the other ECU? I have literally 8,000 pages of information on the vehicle from Audi (ERWIN) but for some unknown reason that info is not anywhere I have looked...just one more for me...

    THANK YOU!!

    DPNW, the difference is miniscule, now In fairness I do know a good COMP for this motor. Most engines 120/170 but on multi valve engines I know can be over 200, so maybe somebody could chim in on history of this motor. IMO, 123-126 not stellar but on bottom of range, would like 150-170, again could be wrong, would be the first time this year, NOT.

    So as RPM goes up so does compression, hence might answer miss fire at idle, then not above. Would like to see running compression as all are so close would just do the easiest one. IF too low are sporting a miss fire.


    Also manifold flaps could create low COMP, but some of these motors out of my wheel house.
