ok, so someone at work got me thinking.
Would it be feasible to retrofit ASR to a facelift B5? I'm not talking full ESP, just basic traction control.
could it be as simple as swapping the ABS modulator to one that supports ASR, such as an S/RS4 B5 or a B6.
Looks as though the Bosch 5.3 unit 8E0614111G or 8E0614111AJ can be re-coded to be Non CANbus, So could be a winner...
Anyone done this before?
