And now the s/s is off as default during startup (you have a light in the s/s button). And if you want to enable the s/s again during your jurney, just push the button and the light goes out, and s/s is back on. No warnings, no hack, everything works as if you just had pushed the button after start up, exactly like your hardware hack. And I am SURE that there is a procedure like this on the mk7 also. What value do you actually have in adaption channel 34 ? (remember to login first).
Talle: Hm... not sure how to say this any other way, but to my knowledge, there is no "channel 34", or anything like this facility on a mk7 -the fundamental structure of adaptation channels is completely different in the car!
The process of adding/subtracting Hexadecimal numbers to/from a single car-wide bank of adaptation channels to change settings for SS simply doesn't apply to MQB platform vehicles. In MQB models, each control module has it's own individual bank of adaptation channels (except of the auto transmission control module at address hex02 - which has no adaptation channels at all).
As I said previously, in total the mk7 will have in excess of 3,000 adaptation channels spread across the 10-20 control modules. Each adaptation channel is specific to it's related control module and some (many?) can only be changed with security access codes that apply to a specific control module. So there is no single security access code for the entire bank of adaption channels (as I suspect that there is in the Audi).
For example, if I search for the term "Start Stop" in the database of adaption channels for my car, I get 22 hits. These SS adaptation channels appear in the BCM, the CAN Gateway, Auto HVAC -Air conditioner, and the Engine control module. So SS is integrally intermeshed into the car's DNA on MQB platform vehicles
It's great that in your Audi, the designers have simplified the control of SS into a single adaptation channel - #34. Alas this does not appear to be the case in the mk7 (or at least, no one has found this to be the case in a mk7 since the cars were first released).
This said (and as indicated in my VCDS tweak instructions to disable SS), later models of the mk7 are fitted with the control module Acc/Start Auth. (address 05, HW:5Q0-959-435). This controller has only one adaptation channel with the descriptor Deactivation of start-stop function and default setting is not active. However, to my knowledge no one has been able to disable SS using by this setting.
Never-say-never, perhaps someone will find a way to replicate your tweak - for now though, I suspect that the Audi solution simply won't work on a mk7, I would be delighted to be proven wrong
Again, many thanks for your interest
Don

Please don't PM to ask questions about coding, or vehicle repairs. The better place to deal with these matters is on-line, in the forum proper. That way you get the benefit of the expertise of the wider forum! Thank you.

I'm not skilled in electronics and I have only done basic things like strip wires and solder things together but never have I built a circuit from scratch. I did however pull the electrical connector from the switch panel and post some pictures and hopefully you can comment.
