ESP Programming and Air Suspension Compressor Override Module

[zipster31]

Hi folks. I have 2 issues if I may.
First issue: The ESP module needs reprogramming apparently. It's failing to communicate with the instrument cluster. Does anybody know where I can get this programmed (diagnostic shop said the ESP module may have been changed and does not have the same vin number as the original.
Second issue: I have replaced the rear air suspension with springs. How to override the fault light on the dash? Do I need a diode of suchlike in the air compressor circuit? Or is there a module I can buy that wires into the same circuit somewhere?
Thank you in advance

Get it on Xentry and have the car told it’s no longer got that option, error will automatically go away.

Thank you for the reply. Do you mean get the ESP reprogrammed by Xentry?

No, the ECU for the car to tell it you no longer have rear SLS.
The ESP needs further diagnosis as it should be plug and play unless it actually needs SCN coding, at which point you can only do that by using online STAR

So I need to have the ECU tested by Xentry?

Main ECU will need to be connected to xentry and have rear SLS coding out, easiest way to do that is to change the model designation to one that didn’t have it as standard. For example on a car the estates have rear SLS as standard, if they were removed and switched to standard springs then the easiest way to stop the error popping up would be to tell the cars it’s no longer an estate but a normal saloon.
