Hi ,
the module is the new version -
+power is taken as suggested by the inwstructions from the harness that is found by removing the

side dash panel - ( RHD car) - opposite side to the fuse box. - the wire loom seams to lead to the light switch.
I have rechecked the earth, power and Can connections.
It is a stange fault which I thought would imply something like an intermittent earth -but I have checked this.
I get the roof error - malfunction ( which then makes the roof inactive ) after a variable time driving in both active and inactive module mode - when it works all functions are working ok.
-- the error ocurs whilst driving and is not associated with roof action. - warning sound and malfiucntion error comes up on display.
Once the malfunction occurs - the only remedy I can find is by interupting the power to the module by unplugging power or removing and replacing the apporpriate fuse. Something is being 'reset' by this action ????
The module then functions ok.
Any further thoughts ?
I suppose the most logical step is to remove the module and retrun it for checking.
