I thought that all of these "mild hybrid" systems used an electric motor which provided the boost when necessary, but also acted as the starter motor and alternator. I suspect that disconnecting the cables to the motor would result in the car never starting.

I am sure that I will be corrected if I am wrong.

Having said that, I would be delighted to receive a B4 in lieu of a D4 for no extra cost.
