Leaving to run errands the other day, the ID.4 threw its first power train caution light, malfunction in the electrical drive train. This was only a caution. The car completed self-test and appeared to drive normally. The alarm was locked in until the vehicle was shutdown at my destination.
The fine manual is not terribly helpful. It tells you to have the vehicle serviced. And that you can continue to drive the vehicle.
It drove normally in B mode.
The next start
When I arrived at my destination, I shutdown the drive after parking and ran my errand. I came out expecting that a real fault would still be present and that the caution message would reappear. If it was a glitch during power on self-test, the fault would not return.
When I started the vehicle to depart home, I engaged the drive (B mode) while the vehicle was still working its way through self-test. This time, I patiently waited for self-test to complete. No caution message. ID was happy. We call ours Winterkorn.
Winterkorn does not like to be disturbed while he is performing power on self-test. Engaging the drive may have caused a flicker on the high voltage during self-test that caused the caution. So now I’m careful to let Winterkorn wake fully before attempting to make him move.
We named our vehicle after the CEO who set Volkswagon Audi Group on the path to electrification. Without the Diesel emissions scandal to spur action, it is likely that VW would have made a less aggressive transition to battery electric vehicles like Honda, Mazda, and Toyota are. To get well from the extreme embarrassment and harm he caused the company, his replacement announced and the company is executing an aggressive transition to electric vehicles.
