I found the solution. Thought I should post it incase anyone else suffers the same drama. If the numbers on the ECU match up you should be able to just plug-n-play a 2nd hand one.
So you're looking for the number above the barcode eg. 92190063,92179450
and the Service number on the same sticker eg. 12600940
If the two match you should be in business without having to replace the PIM module or BCM etc.
Justcommodoresspares are the ones that sorted it out for me.
Good luck guys, peace.
Re Serial Numbers, Part numbers on new 2004 VZ SV6 5speed auto sedan ECU.
I bought a "new" ECU for my VZ SV6 recently. Fitted with 12 months warranty $990 by a home visit guy here in Brisbane area.
Looking at serial numbers and such stuff, I thought I would add my white label "data" from the new ECU. My understanding these are brand new from Bosch USA, and the deal was that Bosch required the old ECU as part of the replacement process, otherwise I paid another $120 to keep it.
I have two white labels on the new ECU
Label 1. 208095 004584 01020
Label 2. 19260509 E55 YLZC
Ser No: 19260509
1039S10782 8627004584 208095

Using some of your comparison part numbers nothing I have seems to match. The guy used the Tech2 and took about 45 minutes to download software from his laptop to get everything to match up. The engine has been very good since the new ECU was fitted. The diagnostic guy said the my ECU was a Bosch factory unit, (They bought ECUs from USA direct as did Holden Australia) hence the return of the ECU assembly. The early 2004/2005 problems were fixed in this new unit. Only time will tell if my decision was the right one.
I tried to add an image of my original ECU white label. Couldn't get it to happen, so made a new post with the original ECU label.
