Why I'm asking is that the module is quite often declared stuffed when its actually a broken wire in the door or socket, and I believe there isn't any difference between models but I'm not 100% on that.

My problem relates to the vehicle immobiliser being armed now permanently with other symptoms being the driver door lock is no longer actuated by the key fob or door control panel (all other doors are actuated ok). I started a thread documenting my immobiliser woes here
Help WG immobiliser issues which you kindly responded to as well.
You are quite right in commenting that the BCM is often fingered as faulty even though door pillar wiring has broken or is almost broken and short circuiting. Unfortunately in my vehicle there is no broken or shorted wiring and it looks like the BCM really is stuffed (this is the opinion of the auto electrician who has been diagnosing the problem).

Try www.rockauto.com, they might have new one.

Yeah I tried Rockauto first and didn't find a BCM available at all, only a very reasonably priced ECM... sigh. I've already decided to purchase the new module as I'm due on Fraser Island soon and it's all getting too tight to mess around
According to the auto electrician WJ/WG BCM's can actually be re-associated with other modules but it takes some effort to flash and then recode them specifically for your vehicle via a DRBiii. I don't know whether to believe this or not as I was under the same impression as turbomart. At any rate the revised price is $1000 for the new BCM and I'm out of time so in it goes.
Never could track down my specific replacement part 05083892AD used anywhere but I believe the last two letters refer to the software revision while the numerals are the part number.
Thanks for the responses guys!
