T6.1 Steering Assist part/no's

[Power ut]

Yea this is what I tryed I asume rack must have lost codeing and basic settings so won’t work either on bench by turning the rack rack full left full right

Have you watched my YT video above?

yes. Still dosent work , pissed isn’t the word. Surely all the racks carnt be buggerd I carnt evern conector can to j500 as I’m useing audi cangateway to conect to ecu/ dsg/ abs etc as it says no signal

I tried with terminal 30 and 31 only and power steering works after completing the full clockwise and full anticlockwise rotation cycle.
Without terminal 15 the steering rack goes into permanent sleep mode.
So 15 is required to keep Power Steering Unit alive.

Also dreaming about this retrofit for T5.2-T6
Adding possibility to throw away (finally!!) annoying wet,dripping,flowing,knocking liquid power steering rail

Found some hardware offers in my country
EPS itself: 7L1423051F ~850EU
Subframe: 7LA499029B ~600EU
Stabilizer: 7LA411303G ~150EU
+short aggreagates belt needed, will measure and fit it after a legacy power steering take off
But i'm sure the investment worth it.

Still not clear if PQ25 gateway support steering assist address 44
and what a loom will look like, with a CAN-bus or without, possible to bring Lane Assist or not
Thx

in order to run it separately! you shouldn't connect CAN-bus at all. Seeing at least some messages, the Can rail understands that there is a data bus and waits for messages from there! completely turn off the Can bus and supply power to the rail, then it will go into emergency mode!

EPS motor PCB for reference. Will try to extract the firmware unless someone can obtain an copy [7LA909144D] from ODIS etc.

Looks pretty similar to this:

Have you ever gotten around to pursue this further? It seems like there are no "easy to acquire" firmware files online somewhere for these type of eps racks.

sorry to wake this thread up !! i recently looking for a better solution for my van and it has a facelift! it is a t5 but has t6 front end and other bits for making it to look like a t6 and subframe from t6 but my power steering went out and now looking into to retrofit electric power steering rack from a t6 is that possible? since what i can read u need to feed it +12 and minus and key on power +12 to pin where in what pin do i need to feed that in the white circle? so i dont burn the rack motor up

Has anyone made this work yet? I have one I want to fit to a T5. Considering modifying a T5 subframe to accept the EPAS Rack as the mount for the power steering is different. CAN messages for the EPAS I have reverse engineered and can get assist control but these don't match the PQ35 messages from the cluster so need a Man In The Middle device to translate them to the MQB format for vehicle speed at least. I'm working on this atm. But playing back MQB canlogs with set vehicle speeds I get proportional assist. Enable line removed gives a default assist at 50km/h.

It'd be great if anyone has more information on controlling these racks, I'd like to add lane assist in the future.
