Inhibit the car = Inhibiting the APS via the diagnostic menu. I think it's in the "Controls" sub-menu? You need to Uninhibit in the same menu.
In total my car was in inhibit state for 3 weeks which I charged to 171-172 miles; when the package came back in 3 weeks my car had 144 miles range remaining so lost about 27 miles in duration. When you inhibit the roadster the phantom drain is as slow as a model S if you leave it sitting; the average phantom drain shutting down or inhibiting abs for 3 weeks is normal for 27 mile loss. When you un-inhibit the car you push the vds screen and you will be in the same control settings menu you put the car in inhibit state. You will see "unhibit" and 12v operations will come back on.
I am in for a group buy, if possible. Otherwise I will do this sometime in the next 8 weeks (before winter arrives here).
