Based on the information you've given, it would appear that Part No 30758260 is the earlier type of tensioner & belt, & Part No 30758261 is the later one. My V40 1.8 B4184S2 is a year 2000 & my engine number (as on V5 doc)starts B4182169*** . I know that mine uses Part No 30758261.
As the car hasn't been used much since the last belt change,.. If you remove the top timing belt cover, the part numbers may still be visible on the belt & you may be able to cross reference them if it's a different make?
It's also commonly said that .. original volvo water pumps can last the lifetime of the car ? So give it some thought before changing it, but if it's been swapped at some point for an aftermarket one, then swapping it back to a volvo OE part would be a good thing ?
