I went into the dealer in Winchester VA to look over the new PS on the 825i. It is electric; you can steer it with the engine off to try it as well. The control unit is integrated on the steering column up under the front cowl behind the dash. Very nice and much better than the WRENCHING i have to do on my 620i, especially in 4WD with the diff locked! The new machine seems alot quieter too!
My dealer is also working up a price for me
