The Volkswagen Golf Mk7’s Start-Stop (SS) system, designed to improve fuel efficiency, can sometimes be intrusive. This guide provides two proven VCDS (VAG-COM Diagnostic System) tweaks to permanently disable the Start-Stop function on your Golf 7: the Temperature Method and the Voltage Method. Before proceeding, consider potential legal and environmental implications of disabling this feature.
Disabling Start Stop on Golf Mk7: Temperature vs. Voltage Methods
While both methods effectively disable the SS system, their applicability varies depending on the model year (MY) of your Golf Mk7. Feedback suggests the Voltage Method works best on later MY models, while the Temperature Method is more suitable for earlier versions (e.g., MY13).
Method 1: Temperature Modification with VCDS
This method involves adjusting the temperature thresholds for Start-Stop activation. Credit goes to “Allenlin” from Golfmk7.com for developing this tweak, initially tested on a 103 TDI. A video demonstrating the disabled SS using this method is available: Start/Stop disabled-Golf mkVII.
Steps:
-
Access CAN Gateway: Connect your VCDS to your vehicle and navigate to 19-CAN Gateway.
-
Open Adaptation: Select Adaptation – 10.
-
Modify Minimum Temperature: Locate (1)-Start/Stopp Auntemperaturvorgabe-Minimaltemperatur in the channel list. Change the New value to 50 (default is -50.0). Click Do it! and then Add to Log to save the change.
-
Modify Maximum Temperature: Find (2)-Start/Stopp Auntemperaturvorgabe-Maximaltemperatur in the channel list. Repeat step 3, setting the New value to 50 (default is -50.0). Click Do it! and then Add to Log.
Method 2: Voltage Adjustment Using VCDS
This method manipulates the voltage threshold for Start-Stop engagement. Note that this method might not be accessible on all Mk7 models (e.g., MY13). It has been confirmed to work on MY14 models.
Steps:
-
Enter CAN Gateway: Access 19-CAN Gateway as described in the Temperature Method.
-
Open Adaptation: Select Adaptation as in the previous method.
-
Adjust Start Voltage: Find Start/Stop start voltage limit in the channel list. Enter 12 in the New value field (default is 7.6V). Values above 10V should work, with a maximum permissible value of 12.1V. Click Do it! and then Add to Log.
Golf R Specifics: Acc/Start Auth. Control Module
Golf R models might have an Acc/Start Auth. Control module (address 05, HW: 5Q0-959-435). This module features a single adaptation channel: Deactivation of start-stop function. The default setting is not active. Changing this setting to “active” might disable Start-Stop, although this remains untested due to reported access limitations to this module.
By following these VCDS modifications, you can successfully disable the Start-Stop system on your Golf Mk7. Choose the method most appropriate for your model year and enjoy a more personalized driving experience.
