thanks to Lee i have managed to retrofit the mfsw to my a4 b5, but came across a few things that may help others.
if you replace the steering slip ring, which also contains the steering angle sensor for esp, then you will need to recalibrate/zero the new slip ring as well as recode the abs module. same thing happens if you power up the ignition with the existing slip ring disconnected.
this also loses the soft coding of the abs controller as well which in turn disables both the abs and the esp.....which is where i found myself.
you cant recalibrate the slipring unless you recode the abs controller first with the ignition still on, and both the abs coding and slip ring calibration can only be done if you use specific login codes (different for each operation) with vagcom
the abs coding depends on the engine, gearbox and brake calipers and the vagcom login code depends on the soft coding of the abs module...

Encoding control unit
After installation of a new control unit -J104 or a new steering angle sensor -G85 the ESP system must be encoded again. After encoding the steering angle sensor compensation must be performed.
Encoding of ESP control unit is designed to adapt the control unit to the vehicle.
Zero position compensation must then be performed for steering angle sender -G85.
Coding is only possible after the workshop code (WSC) has been entered into V.A.G 1551.
Note:
If control unit has been encoded with code 00000 or with a code not appropriate to the vehicle the ABS warning lamp (K47) and the TCS/ESP warning lamp (K86) will light up continuously and the fault 01044-Control unit incorrectly codedwill be stored in the fault memory of the control unit.
The brake caliper type must be determined in order to perform the login procedure and the encoding (see illustrations below).

Steering angle sender -G85 zero position compensation
• ‒ Zero position compensation with the steering angle sender G-85 must now be performed.
• ‒ To initialise steering angle sender, turn steering wheel at least 10 degrees in any direction
• ‒ Move steering to zero position. Maximum tolerance ± 5 degrees
Note:
The diagnosis must not be terminated nor the ignition switched off between the procedures "Encoding control unit" and "Steering angle sensor compensation". Otherwise the entire process would have to be repeated.
still in abs module after doing the above,
login with code number 40168
04 basic settings
001 go (this may have automatically gone in if you pressed the up arrow key by the channel selector)
so the message should say Steer. angle sender compens. OK
in summary, after doing the module soft coding with the correct login, you make the appropriate steering wheel movements as above then you relogin using the number 40168 and trigger the steering zero calibration
through basic settings channel 1 - if you use [/table]

I need to recalibrate my control unit and those codes will come handy.
