    Thanks for the scan. I replied to this thread with suggestions for some conflicts I spotted. Please try those suggestions first in an attempt to get all coding values back to a factory-like condition before we try making additional modifications.

    Using the latest condition 09 coding as the baseline

    ... I would try enabling Byte 12, Bit 1 Daytime Running Light (DRL) adjustable (Manually AND/OR Instrument Cluster) to see if it adds a new MFA/Cluster menu at all, and if so, if that new menu happens to toggle on/off DRLs. That would result in:

    Code:
    7B994B9A08AB0B000939268026C886C54BC6720E60A571F0B0A050032844
    If it doesn't you might want to undo that change.

    The only other coding specific DRL option I see that may be worth experimenting with isn't in the English file: LC,23,5,Tagfahrlicht aktiv wenn Standlicht aktiv

    23/5 is enabled so it may be worth turning it off just to see what the end results are.

    Dana, thank you for your help

    I tried both the changes:

    1) Turning on DRL adjustable in Instrument Cluster: This did not work and I did not get an extra menu, On Googling I found out that people say that PQ25 does not support the "Convenience" Menu so this doesn't work for non-PQ35 cars

    2) Byte 23 Bit 5: This turned off the DRL permanently and the LED strip in the headlight never illuminates even on AUTO or OFF or LOWBEAM

    Thanks for testing both. Now that you mention it .. I thought it was possible to enable some cluster menus on non-PQ35 cars but that must have been for non MFA cars rather than the objective here with factory MFA. Upon reflection I found this https://forums.vwvortex.com/showthre...FD-on-your-MK6


    Moving forward, I don't have any other coding suggestions to offer.

    From the hardware point of view the AW0 (i.e PQ25) wiring diagram I located lacks proper identification of the connections to E1 but T10h/8 is terminal 30 (and a larger gauge wire) so I'm going to assume that this applies to the internal function of your switch: 8 & 9 = Constant in off position (DRL/TFL)

    Useful sources for comparison include Don's contributions in posts 13+ here: https://forums.ross-tech.com/showthr...l=1#post196256

    .. and this oldie which may go a long way when you pull the E1 headlight switch: https://forums.vwvortex.com/showthre...hts-(MkVI-GTi)

    Keep in mind that both the well-labeled example wiring diagram Don used -and- JTwGTI's car were both PQ35s however the info should be useful if you decide to remove the switch and pull the green/white wire out of terminal T10h/9 to see if that disables DRLs when you plug it back in. That was the easiest way to disable early (2011 - 2012era) Mk6 Jetta models per the Daytime Running Lights (DRL) section here: http://wiki.ross-tech.com/wiki/index...weaks#Lighting

    If it happens to disable them you could either shop for a switch that has extra functions or just put a new switch in-between the headlight switch and the BCM on that wire which would allow you to turn them off manually.

    Alright thanks! I'll remove pin 9 from the switch and update you with the results!

    @Dana: Galvanized into action by your intriguing research - I had to take a look at how the Golf version before the mk6 (my previous WD extract) managed the LDS function wrt the DRL. The arrangement for the Golf mk5 looks a bit like this:



    So - based on the WD s for a cohort of 2 x Golfs models (actually, it's 3 x Golf models because the mk7 is the same), it would appear that there has been a consistent design approach accross the models regarding how the DRLs are wired: the 0 position on the LDS consistently applies a T30 Voltage to the "TFL" pin and it's the absence of this voltage that switches-off the DRLs (with the consequence of turning-on some variant of the night-time lights). Compelling stuff, IMO!

    Dana, Don

    Disconnecting pin 9 at the head-light switch just made the car turn on the low-beams and the tail-lights

    Disconnecting pin 9 made the car act the same as if the entire headlight switch was not plugged in

    Thank you both for your help

    Also, Don, where do you get your WDs from? The WD I got from erWin does not show the internal wires of the light switch. It shows me the lamps and the switches but not the wire connections or the wire connections to the terminals

    ^^^gokarty: the amount of intra-switch information on erWin WD s seems to vary with the particular car and with the specific model: some WD s simply show the LDS as a "black-box", while others are more generous in their depiction of the inner working of the part.

    I have no idea how those in the "Vaterland" decide which approach to adopt (I learnt long ago that the will of these omnipotent deities is well beyond the fragile reasoning of our feeble minds! )
