    ^^^^ that's great - the long code strings are the same, the module types are the same and only 4 x different channel settings!!!!

    So..........I'll ask the obvious question: what happens to your autoscan DTC s if you plug-in the old hex55 channel settings into your new hex55 module and clear the errors ?

    hmm...... that's a fairly fundamental question for a VCDS user that's swapping modules to ask!

    Try this:
    1. Connect the VCDS cable to the OBD port - connect to your laptop and fire-up the software
    2. On the main VCDS screen click on select under Select Control Module
    3. On the Select Control Module screen, click on 55-Xenon Range
    4. On the Open Controller screen, click on Security Access-16
    5. Enter the magic number 20103 into the Enter security access key box and press Do it!
    6. Back in the Open Controller screen, click on Adaptation - 10
    7. You will then be presented with a screen like below - not the same entries, but the same layout
    8. In the box that I have labelled "1. Enter" type the Tag number for the 1st channel in your list and then select the down-arrow that I have identified as "2."
    9. Select the correct adaptation channel from your list
    10. You will then be presented with a screen like below - not the same entries, but the same layout
    11. Enter the channel setting number from your old module into the New Value box and press Do it!
    12. After acknowledging the prompts, you should see a screen that confirms the changed setting
    13. Repeat for each of the other channels and exit the module screen


    Then open the autoscan screen- I like to run an autoscan before clearing DTC s because I then have a "before" record on file.
    Press the Clear all DTCs button then run an autoscan

    Don

    PS: while I still believe that it's worthwhile trying to make the changes to your hex55 module- I'm a tad concerned by the specificity of the numbers in the adaptation channels in your list. I've not made these changes - but the T15 voltage for example, is specified to 3 x decimal places! This might be a number that is generated by a calibration process - perhaps?

    when you say Tag numbers I assume you mean the IDE numbers, i.e ENG102296? sorry for being such a newb, just want to be clear because when I added the eng number I there was nothing to select in the channel pull down menu

    paul: I'm sorry that my explanation of this process has become so complicated for you (I can only blame my thick Australian accent and an ageing and deeply deficient intellect) - but yes, my use of the term Tag number is synonymous with the IDE (and sometimes ENG, and sometimes MAS) number.

    As for why you can't find the channels - and without intending any offense to Ross-Tech's code-cutters, the VCDS facility is a fairly basic search engine. Anything that's typed into the search box will suffice as a search vector -so you can use any part of the adaptation channel name. Like most search engines, the shorter the the search string, the more hits will be returned in the pull-down list and conversely, the opposite will be true if you increase the characters in the search box.

    But you should have confidence that if the admap for the new hex55 module has identified a particular adaptation channel, then if you correctly enter part of that adaptation channel name into the search box - you will get at least one hit returned in the pull-down list. This certainty is up there with the inevitability of death and taxes

    Ok, so I tried all of the channel numbers in my list, and none of them came up.

    hmm........ I've just had a closer look at your supposed admap:

    Code:
    IDE00018,Voltage terminal 15,11.756, V
    IDE02389,Ambient brightness,126, lx
    ENG103737,Left headlight leveling control value,1024.0, mm
    ENG102296,Right headlight leveling control value,1024.0, mm
    These are not adaptation channels - they appear to be blockmap values?

    What part of my explanation below was confusing ?

    Your instructions were clear, I just clicked the wrong option, here now is the correct option. Also, I noticed that both headlight fuses were blown in the fusebox inside of the car, I have replaced them both, but it didn't fix the issue. Below is the correct admap reading and both the old and the new were the same.

    Paul: bummer!!

    hmm......... my normal practice in this type of "interesting" diagnostic analysis is to take stock at key points in the exercise. So here's a synopsis of the situation thus far (as I understand from your posts) -ONLY as it relates to the headlights:

    First: your auto-scan indicates that the hex55 module is incorrectly coded - but you have advised that in comparing the old and new J745 module, the long-code string and the adaptation channel settings is exactly the same

    Second: The hex D6 and hex D7 modules in your auto-scan report "implausible" DTC between the A31 & A27 modules and the type of lamps in the newly installed headlight fittings. Yet your advice is that the part numbers and software versions of the old and new modules are exactly the same.

    Third: Whilst I have not asked the specific question, I assume that the actual headlight fittings are exactly the same and that no other modules were changed on the car.

    Don't get me wrong - I'm certainly not suggesting that any of your advice is incorrect (quite the opposite - I entirely accept the information provided in your responses). BUT - I'm no sure how to proceed given the 3 x facts above.

    Perhaps someone else here can suggest a way forward - maybe the crash data stored in car is implicated in the problem (I can't see why this would apply)?

    Thanks for your help Don you been a great help, hopefully, I'll have a light bulb moment and will get this fixed somehow without getting Audi to look at it and charge me a fortune., at least the dip beam work which means I can still drive it at night.
