If this has only happened after a service and they updated the software during that service, i'd suggest this is a very likely option.
However, it would make more sense for the roof to only be operable when the engine is running (so the alternator is charging the battery) but the car is stationary. It may take the stationary signal from a wheel speed sensor (usually used for ABS and maybe traction control and similar) and that sensor is faulty causing the roof to not operate - have you consulted your handbook as to why the button flashes? A flashing button usually indicates a fault in the system somewhere so i'd suggest that as the second most likely.

Scroll down to Pg75 of that if you don't have an owners manual, granted it's for 2006 but Volvo don't seem to have anything older on their support site. Are you pressing the brake pedal while trying to open the roof with the engine running? That may help and also if you have any brake light bulbs out or the brake pedal switch isn't working/brake light fuse failed, it may not make any difference to the button flashing. |
The MK2 is completely different to the MK1.
MK 1 only needs the hand brake applied, boot shut and in park if an auto. Although it is recommended to have the engine running whilst operating the roof mine works with or without.
