Question about 2007 BMW 525xi Sedan
As soon as the car is started the computer shows a warning " Active Steering not Active" But the steering works ok. What causes theis problems and how to correct?
The Active Steering system uses a Papst
brushless dc motor to rotate the cage (ring gear) containing the planet
gears a planetary gearbox at the bottom of the steering column. The
motor effectively changes the steering ratio by increasing or
decreasing the amount of gearbox output rotation relative to changes in
the steering-wheel angle input. The resulting ratio depends on the
speed of the car. For instance, a low 10:1 ratio gives high
maneuverability for parking in tight spaces, with less than two turns
of the steering wheel, lock to lock. To track straight at highway
speeds, where even a small steering input can produce a quick sideways
acceleration, the electric drive boosts the ratio to 20:1. Cars without
Active Steering typically have ratios halfway between (specifically
14.1:1 for the BMW).
Now, if your active steering does not work , the car reverses back to power steering and the ratio is 15.1:1 so the car can be driven but the "active steering " is not working and still needs to be fixed.
It the unit needs to be replaced and your car is not under warranty, the repair cost may reach 5000 dollars.

Or refer to your owners manual where it shows how to fix it by turning the wheel thus saving $5000 and the stress of reading an ignorant comment
