    In my experience, postage from here to Oz isn't usually too bad unless the seller has been a cheapskate and sent it by boat I've sent a few things across to Oz including one item to Tasmania 3 or 4 years back. In fact the ECU, immobiliser and keys in my video were sent off to a guy in NZ once I'd finished coding them up and they only took 4 or 5 days to arrive if my memory serves me well.

    Gary: I like your optimism - we will see!

    If I can indulge your kindness a little further -would you mind making a comment regarding my PS question, please (or is my question too specific to the Golf mk7 module on my instrument panel)?

    I've just checked this on my car and can confirm that the value you see for the "Transponder ID current Key" measuring block is the ID of the transponder that is currently inserted into the ignition. In my case, the ID value I saw next to "Transponder ID current Key" was identical to the value for "Transponder ID Key 2". I haven't tried with no transponder because I have an old school non-KESSY setup which still uses an ignition barrel and bladed key. The ignition needs to be on for VCDS to work and I don't really want to start unnecessarily dismantling my key to remove the transponder just to do a test, so I think we can take your results for granted that with no transponder present you always see a "N/A" value against the "Transponder ID current Key" measuring block

    Don, I have a favor to ask. Do you think you can find the combination of pins/voltages on your ignition switch that tells the J527 to turn the ignition ON? I got a J527 here but I was expecting the switch (D - 5Q0 905 849 xx), which I don't have, to be better documented in the diagrams / less complicated than 5x "this pin goes to this pin" Otherwise I might have to source one (horrors). I can't take apart Andy's or Helen's MQB to probe for that info because they're both keyless (horrors, again). Thank you

    Uwe can kill this link if needed but "T6l" is the same connector name in the Mk5 and Mk7. Since the Mk7 diagrams fail to show what's what I suggested ASSuming it it wired like this random 2009 Mk5 Golf:

    We think we have this sorted and my Mk5 diagram theory is busted. Eric's gonna jump T6l/3 to T6/4,5,6

    Yeah that didn't pan out. Good news is the module is talking and i can see the terminal statuses.

    Eric: My test bench is still like a belligerent child - but it has evolved somewhat since the embryonic version in that early picture. Since the picture was taken, I also found it useful to have a separately switchable "S" contact in the ignition switch - this involved modifying the key switch (removing a spring) and extending the contacts for the S switch to an external single-pole-single-throw switch. You might consider doing the same

    Don

    PS: I'm more than happy to fire-up my trusty multi-meter and produce a logic diagram for the key switch connector if you still need it

    I do need it! I'm merely interested in a permanent terminal 15 solution so other modules can power up and talk to VCDS.
