Replace and reprograme a Body Control Unit

Dear Colleagues
I,m about to reprogramme a emplacement BCM-Body Control Unit on the following:
Vauxhall 2013 (GM-Europe), Model: Insignia, 2.0 Liter Diesel.
The original BCM was damaged due to water intrusion and I have the following constrains:
1) I can,t communicate with the BCM; was able to do with the ABS and Elect Power Steering.
2) I'm waiting the Vauxhall server/ Web site to send me the Unique vehicle security code.
3) I will use a second hand replacement BCM. solitaire.onl/ 9apps.ooo/ bluestacks.vip/

Has any colleague come across using the official GM server/ Web site (not an off line stored data) to reprogramme a BCM of somehow similar age; This one got the CAN gateway, so this BCM is the main network hub.
I know there are good degree of similarities between GM north America and that of Europe (and off course there are other differences). I have a rough understanding to select; Replace and program ECU in the SPS ; Service programming system.
The main concern is:
Can this work with a second hand BCM having a data related to the donor vehicle?

I am sure some techs on here can respond keith of new level auto is really savvy on these kind of issues

If you haven't received a reply I'd check with Drew Tech. Google them. They make the programming j-box here in the U.S. as other companies do to but they seem to have the most experience as they sell on AESwave.com and many other sites.

Maybe a call to their tech support line will bring you some quick answers.

I know my cousin in law who works at a auto salvage recycler which is a pretty big company locally had a wrecked 09 suburban he rebuilt back in 2011 and around 2017 he was having issues with locks, windows and everything on the rear of vehicle not working.

Turned out it was the BCM had shorted out as things had shifted in the wreck in the firewall area where the wires went between cab and exiting cab and he wound up putting a used BCM on the suburban after the electrical repair was made. They reprogrammed the used module. GM has the online programming and you have to be online and have a constant steady power battery maintainer as voltage has to be steady and not fluctuating. Also here in the U.S. they say you want to have a battery maintainer that'll do at least 100amps for up to 3min as during the programming it can draw a lot of power intermittently.

Search for GM TIS web or something line that as they don't allow offline programming that I'm aware of. Keeps theft down.

What did you wind up finding out with this issue you were having? I was curious as this is a area that I like to learn in.

To repair the BCM or any control module for that matter, they have to be reprogrammed which means that a dealer or some specialist must be one to complete the task because they monitor the security codes that enable reprogramming of these systems. mybkexperience mcdvoice
