The full story
The contribution adds remote cabin pre-conditioning and the network-wake handling needed to communicate with the e-Golf's climate controller. Its author describes using Claude alongside compiler feedback, captured CAN traffic and a native test suite.
They report tests on their own car, including starting from a sleeping bus, and describe standing down when the original telematics unit is active. These are the author's tests of an experimental contribution, not independent vehicle validation.
