You are triggering me more. JK. All in good fun.

That is what I have read but I'd LOVE to see a nice YOUTUBE of someone doing it.

These cars are very touchy. My low battery triggers a BDC error, confirmed by the dealer. So the voltages have to be in a pretty narrow band of "correct." I am not sure if real damage can occur to the control units if the voltage is low. Rolling computers.

A volt meter would be nice in the car.....um.....
