Hi , thanks for the advice but either I'm doing it wrong or the car needs me to log in first. When I try to change the coding from 0007175 to 10758 vag-com tells me that coding should be at least 7 digits worth so I tried adding 0s (0010758) but the coding remains the same and the DTC is still displayed.
I called the scrap yard to ask them for a refund or a different pump but I got turned down. So this means I have to get this one in a working condition.
My car has a G250 fault too, even though it never had a G250 sensor fitted (steering rack has a blank casting where the G250 would go). I suspect mine has a Skoda or Polo pump fitted so i've ordered an A2 replacement. Whilst investigating I turned up the following info from ELSA that may help people in future:
The A2 had two versions of the ABS/ESP System depending on the year. These were the Mk20 and the Mk60. You ccan find the info below in the VCDS .lbl files.
The different part suffixes tell you which one your car has. A, B for MK20 and C,D for MK60 as follows:
8Z0-907-379-MK20.LBL,8Z0-907-37?-A ; MK20
8Z0-907-379-MK20.LBL,8Z0-907-37?-B ; MK20
8Z0-907-379-MK60.LBL,8Z0-907-37?-C ; MK60
8Z0-907-379-MK60.LBL,8Z0-907-37?-D ; MK60
The coding is different too (hence the problems changing it in a previous post)
Coding for MK20:
Brake Electronics (J104/MK20) Coding
10758 = 1.4l/55kW MPI (electro-hydraulic Steering)
10758 = 1.4l/55kW TDI (electro-hydraulic Steering)
10764 = 1.2l/45kW TDI (mechanical Steering)
10765 = 1.2l/45kW TDI (electro-hydraulic Steering)

For the MK60 the coding is different between the C and D variants:
C00,Brake Electronics (J104/MK60) Coding
C01,Control Module "8Z0-907-37x-C":
0019470 = 1.2l/45kW TDI (mechanical Steering)
0019474 = 1.2l/45kW TDI (electro-hydraulic Steering)
0019463 = 1.4l/55kW MPI
0019591 = 1.4l/55kW TDI
0019599 = 1.4l/66kW TDI
0019471 = 1.6l/81kW FSI
C09,Control Module "8Z0-907-37x-D":
0007182 = 1.2l/45kW TDI (mechanical Steering)
0007186 = 1.2l/45kW TDI (electro-hydraulic Steering)
0007175 = 1.4l/55kW MPI
0007303 = 1.4l/55kW TDI
0007311 = 1.4l/66kW TDI
0007183 = 1.6l/81kW FSI
