Disable Start/Stop (Bluemotion) on Golf mkVII - VCDS tweak
The following two methods can be used to permanently disable Start/Stop (SS) on a Golf mk7:
(1) Temperature Method, or
(2) Voltage Method (as an alternative to the Temperature Method)
From feedback that I have received from forum members (thanks jonoz and Fontana), it appears that the Voltage method is applicable to later "MY" models and the Temperature method can be used on earlier "MY" models (i.e. my13 in my case)
Before proceeding with this tweak, consideration should be given to any legal and environemtal factors that may result when disabling this facility.
(1) Temperature Method These instructions were sourced from the Golfmk7.com site. Grateful acknowledgement to the author "Allenlin" who has said that the VCDS tweak was developed on a 103TDI. Allenlin has produced a short video which shows that SS has been disabled (see the link below) I have implemented this tweak on my mkVII, and I can vouch that it works.
3. From drop-down channel list select (1)-Start/Stopp Auntemperaturvorgabe-Minimaltemperatur (it's almost at end of channel list)
In New value box, enter 50 (default stored value = -50.0)
Click Do it! tab

4.From drop-down channel list select (2)-Start/Stopp Auntemperaturvorgabe-Maximaltemperatur (it's almost at end of channel list)
In New value box, enter 50 (default stored value = -50.0)

(2) Voltage Method (alternative)
The voltage method is not available to all mk7 models (my own my13 vehicle will not allow access to the Adaptation channel below). However, I have confirmed (by viewing the Adaptation Control Map for Address hex19) that this method is available for the my14 model.
Instructions
1. Enter 19-CAN Gateway (see screen shot above)
2. Click on Adaptation (see screen shot above)
3. From drop down channel list, select Start/Stop start voltage limit (it's about 60% down the channel list)
In New value box, enter 12 (default stored value = 7.6V) Note: forums report that a value greater than 10V will work for this tweak - maximum permissible value =12.1V

EDIT: If you have a Mk7 Golf R then you could have Acc/Start Auth. Control module fitted to your car (address 05, HW:5Q0-959-435) This controller has only one adaptation channel whose sole function is disabling Stop/Start. The adaptation channel descriptor is Deactivation of start-stop function and default setting is not active. It may be possible to change this setting to active (untested).
I've had two replies from forum members about changing the setting on this control module (thanks jonoz and fontana). Both have advised that they were unable to gain access to this module.

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.
