How to find the right spare CODE?

[DeS3]

Hi guys,


due to a problem, I changed the steering box and i found the spare by giving the VIN to the spare shop.
After installing it by an independent workshop, the esp/asr light came out but mechanically no probs. This happened twice, with 2 different steering box spares (both regenerated, so no straight from scrapyard).

I brought it over to Citroen to clear the code, they said that the mounted steering box had no ESP (?) so it wasn't the correct one. It goes without saying that getting it fixed by Citroen will be 1.5k vs 300 if I manage to find the right spare and get it mounted.

Citroen is reluctant to elaborate more about this issue, Ideally they should be the one to give the exact spare code but they aren't.

My questions are.

1. how is it even possible that a steering box for a DS3 doesn't have ESP and some others do. ESP is not an option so it must be on all of them.
2. how can i make sure I'm getting the right spare to avoid the problem again? It seems that VIN is not enough
3. Are the codes actually guarantee an exact match and why there are so many?

Attaching a screenshot of a potential spare I found who does mention ESP in the steering box

Cheers

I'm guessing, but maybe the part is common across the Peugeot/Citroen range and only the DS3 or high end other models have the ESP? If so it would seem that your sellers are selling the wrong part if, as you say, all DS3s have ESP

Okay I take it you are changing the steering rack? On certain DS3 models there is a ESP module attached to the rack. It sounds like your car is equipped with ESP (look for a button down on the right) and you are fitting a rack without, thus the ESP throws up an error when it can't communicate with the front of the car.

My suggestion is that the rack is not being supplied correctly, I would suggest either sourcing the rack from Citroen or trying another genuine supplier.
