Why because the battery went flat now i think it's broken the control box on the body, it controls the ignition and starter I have lights on dash etc but on turning key they go out. Told its ignition module or body control module!

Head aches any way of a reset or fixing it or sealed unit ?

 

I doubt your problem is more than a bad connection, assuming you didn't connect the battery with reverse polarity at some point.

 

Put another battery in that's fully charged and try again before going any further..

 

Was the module afer all replaced and car fires up and runs
