Local garage has diagnosed the control module which apparently sits in the wing, and say they don't really want to do it.

Question is, can I just take that out and buy a used one with the same number and fit it, or is there something that a dealer ir indy need to do with the software to make it work?

Cheers,

This is quite a complex circuit involving 3 major components one of which you have already eliminated as the cause , the reason they don't want to do it is because they don't know how it works and if they spend £300 on it and it doesn't fix it they will be stuck with the rest of the bill to fix it which could easily be £800 or so ..!
Your really need to take the car to the only specialist there is and that is the dealer .. they know how it works and what signals to check and what those signals should be . Therefore they will be able to tell you exactly what is wrong and how much it will be for a 100% first time fix ...

you have probably already wasted a lot of time and money on the problem ....
