Hi paul, the main control module has a fault but it isn't as simple as that, the new control module is supplied unconfigured, you need a special smart card reader & smart card for the percific model to be able to read the data onto the new module. This can only be carried out by a trained engineer & it is costly, we charge approx £150.00 - £175.00 depending on model.
I hope this helps.
