You will need VCDS and if you or a friend has access to it then you need to do the following. This isn’t a VCDS tutorial so I’ll assume you know how to do the below to activate it:
- Select Contol Module 09 in VAG-COM/VCDS
- Go to Security Access
- Type 20113 and Login
- Select “Adaption – 10”
- Select Channel 34 and read
Now this is where the cool stuff happens and you have three options depending on what you want your Start / Stop Button to do…
- Start Stop as Per Default after each ignition. On to off
- Reduce the number by 4 (Effectively Bit 2 to 0)
- Start Stop with Memory Function (Like the video)
- Change the number to 32 (Effectively Bit 5 to 1)
- Start Stop with inverted display (LED on switch is opposite)
- Change the number to 64 (Effectively Bit 6 to 1)
