Permanently disabling the Start/Stop (SS) system on your VW Golf Mk7 can be achieved using VCDS. This guide outlines two methods: the Temperature Method and the Voltage Method. Choose the method that’s compatible with your Golf Mk7’s model year (MY).
Understanding the Methods
Before proceeding, consider any potential legal and environmental implications of disabling the Start/Stop system.
Temperature Method (for Earlier MY)
This method involves adjusting the temperature thresholds for SS activation. It’s reported to work on earlier models like the MY13.
-
Access CAN Gateway: In VCDS, go to 19-CAN Gateway.
-
Adaptation: Click on Adaptation – 10.
-
Minimum Temperature: Select (1)-Start/Stopp Auntemperaturvorgabe-Minimaltemperatur from the drop-down menu.
- Change the New value to 50 (default is -50.0).
- Click Do it! and then Add to Log.
-
Maximum Temperature: Select (2)-Start/Stopp Auntemperaturvorgabe-Maximaltemperatur from the drop-down menu.
- Enter 50 in the New value field (default is -50.0).
- Click Do it! and then Add to Log.
This effectively tricks the system into believing the temperature is always outside the operational range for Start/Stop. A video demonstrating a successful deactivation can be found here: Start/Stop disabled-Golf mkVII
Voltage Method (for Later MY)
This method modifies the voltage threshold for SS engagement. It’s generally applicable to later models (e.g., MY14). Note: This method may not be accessible on all Mk7 models.
-
Access CAN Gateway: Navigate to 19-CAN Gateway in VCDS.
-
Adaptation: Select Adaptation.
-
Voltage Limit: Choose Start/Stop start voltage limit from the drop-down list.
- Set the New value to 12 (default is 7.6V). Values above 10V should work, with a maximum of 12.1V.
- Click Do it! and then Add to Log.
Golf R Specifics
Golf R models equipped with the Acc/Start Auth. control module (address 05, HW: 5Q0-959-435) have a dedicated adaptation channel for Start/Stop. The channel, labeled Deactivation of start-stop function, might offer a more direct deactivation method, though accessibility and functionality can vary. Further testing is recommended. Reports indicate that accessing this module can be challenging.
Conclusion
Using VCDS, you can deactivate the Start/Stop system on your VW Golf Mk7. Select the appropriate method – Temperature or Voltage – based on your car’s model year. While the provided instructions are generally reliable, compatibility and accessibility can vary. Always proceed cautiously and consult reputable sources for the most up-to-date information.
