    There must be a way to upload a file here, but I can't find it. Also can't find a 'help' menu.

    No, we don't want this forum to become a file-hosting service.

    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.

    jgordon: hi and thankyou for a most interesting question! Forgive me if I'm telling you something that you already know, but the device that auto-dims the instrument panel on a mk7 is a photo-transistor that lives between the "7" and "8" numerals on the tachometer dial - see picture below



    Again, my apology if I'm "teaching grandmother to suck eggs" but a photo-transistor is a semiconductor device in which the electrical-gain of the transistor is modulated by the amount of light that falls on its transparent body. In the case of the mk7, the device modulates the dashboard illumination via a series of adaptation channels in the module @ address hex17 related to "dimming_characteristic_curve_adjustment" - as suggested by Uwe in a previous response.

    Specifically for the photo-transistor, the hex17 module has 8 such adaptation channels devoted to "X" values and a further 8 channels linked to "Y" values in a mk7. Most of the questions that I've read regarding the photo-transistor gain-curve relates to increasing the illumination during daylight time (usually because of tinted windows) and I've written a set of instructions for this problem which you can find on the link below:

    http://www.vwwatercooled.com.au/foru...ml#post1124686

    In your instance however, the changed characteristics need to apply to the night-time hours, so I suggest that you experiment with the set of "Y" adaptation channels (instead of the "X" channels) in my instructions. Of course, you should note the starting values for the adaptation channels in case you need to revert to the factory settings and it goes without saying that SPECIAL CARE should be exercised in selecting channels because there are many closely worded channels in the hex17 module.

    The other confounder in your experiment will be the access code for the hex17 module. In modules up to about MY16, the security code was as listed in my instructions, but in later model modules, the code changed. I've recently read a post on this forum where a colleague has suggested the following for later modules:

    Good luck with the experiment - and have fun!

    So if I understand correctly, I'm to experiment with the the dimming curve by changing the 2 numbers after the Y1, Y2, etc? The Dropbox file in your link is no longer available. Any suggestion for a starting point?

    gordon:hmm......Of course there is much that is not known about these illusive and mysterious dimming_characteristic_curve channels (at least not much known by me)! Anyhow, while you may be correct in choosing those channels, I had meant that you experiment with the phototransister set of channels (see table below - these are the default values on my MY13 Golf)



    I'm not sure why the link in my tweak instructions is broken (I will try to find the PDF document and re-load it), but here is an extract from the notes that I made when I played with the channels above (way back in 2015):

    For the mk7 Golf, it appears that:
    a) the "X" values relate to increasing brightness levels in the cabin ,
    b) the "Y" values correspond to decreasing darkness levels in the cabin.

    The settings for the adaptation channels indicate that:
    a) The phototransistor has 5 x "set-points" for "X" and 5 x set-points for "Y". The granularity of the "X" values is about twice that of the "Y" values: the range of the "X" values is Hex00-Hex1FD (i.e. decimal 0 - 500), whereas the "Y" value range is Hex00-HexFD (i.e. decimal 0-253), This may be because the human eye is more sensitive to increasing light levels (as I understand).
    b) The set-point for the brightest daylight illumination is "X5" (i.e. the sequence X1, X2, X3.... X5 corresponds to increasing daylight levels in the cabin)
    c) The set point for the darkest night time level is "Y1" (i.e. the sequence Y5, Y4, Y3......Y1 corresponds to darkening light levels in the cabin) .
    d) For a particular "X" channel ( X5, for example), decreasing the hex value increases the instrument panel illumination level during daylight.
    e) For a particular "Y" channel ( Y1 for example), increasing the hex value for this channel will increase the cluster illumination in darkness

    Hope this helps

    Maybe I need to restate my goal: the dashboard is far too bright when driving on a dark road, even with the dimmer switch rolled all the way toward 'dim.' I want to adjust the dimmer switch curve so I can dim the lights further, even 'off' if possible

    gordon: Yes, I did properly understand your original objective - my best (only) advice is to start experimenting with the channels above. As I found when I first played with these channels a few years ago now, there may be side effects on the illumination of other parts of the dash board (like perhaps the MIB screen - but I really don't know). Nevertheless, and notwithstanding the inherent risk with anything new, this is a very low risk exercise since you can (should be able to) revert the settings to their factory values if anything goes pear-shape!

    Good luck and please provide feedback if you proceed - it's the implicit quid-pro-quo for advice given in this place because it adds to the sum of the forum's knowledge about the secret black arts of VW's protocols!

    Thank you Don. As you suggest, I will proceed carefully and gladly post my results here. This may take some time.
