Coding the ABS control unit for a Polo 6n

hello
I replaced the hydraulic block with the control unit in my Polo 6N (year 1997) because, according to Volkswagen, it was defective.
"It is supposed to work after the exchange (used part with the same part numbers). Now, the brake warning light is also on, and the ABS light is on. So, I'm going to my friend to have the error codes read right away."
Result: Error 0144035: Control unit coding.

Okay, let's move on to the question of how the control unit would be coded. I have a VAG 1552, and what is the code required?

Part number for hydraulic unit: 1J0 614 117 A.
Part number ABS control unit: 1J0 907 379.

The simplest way is to disconnect the plug and connect it to the old unit for reading. However, you should note the old coding before disconnecting it. These components are safety-critical. Therefore, most of the information about it is also scarce or has been removed from the public domain (openobd). It's not entirely incomprehensible.

It's a bit problematic because I can't connect the block to the connector without removing the battery; everything is very tight. Is there another way to do it?

Is it possible to reprogram the control unit using VAG 1552? A guide would be really helpful!
Best regards,

That might work, but then probably with VW and with an online connection.

It would be worth trying to read the coding from a vehicle of the same model.

Following Netech (thank you, Nils), the code 01901 should lead to a successful outcome for your vehicle.
