Active Steering Retrofit

[robinasu]

Was anybody successful retrofitting active steering to their E70?

From what I see, it seems doable:

-The Active Steering (AS) pump looks very similar compared to the basic, & Servotronic options. The basic rack has no electrical connections. The Servotronic rack has a variable assist actuator, and the AS rack has Servotronic, planetary motor control, planetary position, and the fail-safe connections.

-The Active Drive (AD) pump seems to be two pumps in one. The Servotronic and basic steering pumps have different part numbers, but seem to be the same in they have the eco function connector. The eco function is a bypass function to pump most of the flow back into the tank to same fuel.

-The schematics show the basic steering to have the eco valve which is activated from the (JBE) Juntion Box Electronics module. The AS option controls the eco valve via the AS module.

-The AS module has connections for Servotronic, planetary motor control, planetary position, fail-safe, eco valve, CAN, and power connections

-It looks like at least one of the power steering hoses needs to be replaced - but not sure.

-E70 & E71 racks appear to be fair game

-Only E70 AS modules appear to be valid. The X71 uses a different module- seems to have functionality to control the torque vectoring rear differential. I don't know, maybe that could be added to the X5 but too much for me.

Some questions from my research:

-Does the X5 need un upgraded DSC sensor

-What do we do with the JBE eco valve connector? Is this coded out or do we need a resistor to prevent a code?

I would say price is the prohibitive factor, even used those active racks are $$$, the last I checked (had some spare time).

Yeah that sounds expensive. But would be a fun project go do!
