Answer
Jagger,
Your going to have to see the dealer so that they can hook the car to the scanner (VIDA) and clear and rest the fault codes. There are some bulletins that speak to the alarm that also might need attention. Sometimes a download of new information is needed. Software is ordered as follows:
The mechanic specifies which article must be ordered, and for what car (model and chassis number). This can either be carried out from the replacement parts catalogue (via the part number) or using the VADIS/VIDA software manager (via the software product).

A dialog box in VADIS/VIDA asks if a control module has been replaced. If the mechanic responds that a control module has been replaced, the mechanic is instructed to connect VADIS/VIDA to the vehicle so that the hardware number and serial numbers can be read off, before the software is ordered.

If the mechanic replies that the control module has not been changed, the system will assume that the car and the Volvo database correspond. A verification which ensures that this is the case will be carried out just before downloading.
