Did you ever figure out that putting the clutch in, turning the engine off, moving the key back to the running position and releasing the clutch was the easiest way to do it? I have had several cars I've had to do this in. Latest was a 2003 Vauxhall Vectra (Opel?) which needed this to get out of "limp mode" if you accelerated in 5th gear above 55mph. Ain't cars fab?

Oh yeah, the reboot with compression start. My wife didn't like it tho. :)

The true problem was a marginal 12 volt battery that caused a "won't go away until reboot" error in the power steering MCU. I realized it when the problem got significantly more common on winter mornings. Asked myself, "what's the part of of an electric power steering system that is sensitive to temperature?"
