E82 Complete Vehicle
The springs and dampers differ from those in the E90 in that they have been adapted to
the E82’s vehicle weight. The front axle of the E82 is fitted with a hollow-type anti-roll bar
for weight reduction and a sport tuned suspension is available as an option on the 128i
(standard equipment on 135i).
The following steering systems are fitted in E82 vehicles:
• Conventional rack-and-pinion steering with Servotronic assist hydraulic pump
(vane cell pump) as standard equipment for all 128i and 135i vehicles.
• Active Steering with hydraulic pump and ECO valve is available as an option.
Active Steering in the E82 features the following optimization measures carried over
from the E70 or E6x LCI:
• Modified planetary gearing
• New control module
• Absence of the cumulative steering-angle sensor on the rack.
Note: The new procedure for initializing the Active Steering (as in the E70) now
also applies to the E82 (because of the absence of the cumulative steer-
ing-angle sensor).
Note: There is no electrical steering lock (ELV) for E82 US vehicles, regardless
of the transmission type.
Dynamic Driving Systems
The Dynamic Stability Control (DSC) has been newly tuned for the E82, containing the
following modifications.
These only apply to the Active Steering models:
• DSC sensor: two separate units, one with and one without a longitudinal accelera-
tion sensor.
• DSC control unit and hydraulic control unit modified.
• Extended diagnostic capabilities due to more precise fault code memory entries.
Note: Vehicles with Active Steering; the operation of the DSC sensor is moni-
tored b
y both the DSC control unit and the Active Steering control unit.
