You are correct, there are two ways for it to relearn either ISTA/D or just pure mechanics.
To the OP, there are two ways you can do this either relearn it with ISTA/D or remove the valvetronic motor and with a screwdriver push the eccentric shaft gear as far back anti clockwise as it can go. Insert the valvetronic motor and connect its 2 pin plug. Then switch the ignition onto position 2 and within a space of 15 seconds, depress the accelerator pedal down to full throttle 10 times and you will hear the valvetronic motor program itself back to factory spec.
