ACC Module - Expert Advice Sought!

ACC Module - Expert Advice Sought!
Hi Everyone,
I'm hoping I might be able to pick an expert brain or two here!
I have the dreaded "Cruise Not Available" in my 2002 XKR - which is supposed to have ACC. It's always been there, I naively bought the car without doing my proper research into how much of a pain in the a** this might be to get this sorted.
So anyway, yesterday I decided to whip the module out and have a look. Two things of note:
1. When I started the car without the module in, the car went into "Failsafe Mode" and I think a couple of other errors came up. When I put it back in, it went back to just cruise not avail (interestingly, I usually have to drive the car for a hundred yards or so for that to happen - but it immediately comes up with no module in).
2. The part I took out had the part number: LJE-1960-AB ...... BUT, what I thought was interesting was that that number was also scratched into the metal of the part by someone else. Now, I'm thinking, that, that's the sort of thing a scrap dealer might do if they thought the label was getting faded (which it was)... but I can't really imagine a normal punter doing it, then putting it back in (if you see what I mean?)..
So, two questions:
1. Is the response to unplugging the module in point 1 what you would expect? and...
2. Is it possible / likely that someone has bought a replacement part from a scrappy and plopped it in, but potentially put the wrong / incompatible part in... I have looked for part lists etc, but not come up with much of any use? Might this cause the symptoms above?
Thanks so much for anyone who can help / provide advice. This is about the only thing wrong with my lovely car and I don't really know what I should do about it - (particularly as I'm questioning exactly which part number I should be looking for and they seem hard to come by anyway!)
Best Regards
Andy

Oddly the first suspect is your battery.
A feeble battery can cause all manner of problems including this one.

Update
Just to keep anyone who has the same issue updated.
After a lot of googling etc, it seems that the particular module with the part number: 2W98-9AA12-AA (or AB I think) has a known issue causing this fault. I spoke to BBA Reman who say they have (so far) had a 100% success rate in fixing this issue and it costs around 600GBP - way, way, way less than a new module which is over 2K I think.
As soon as I get round to sending the module off I'll report success or failure!
