I've had it in my 2015 model V60 D5, only 18k miles. The problem I have is that I kept unknowingly interrupting the DPF regens, the car would much rather regen more often and dilute the oil than risk raising a message on your dash about a full filter. It's very difficult to tell when it's regenerating unless you know what to look for, it's almost like Volvo don't want you to know it's fitted with a DPF. The gents in maintenance I've spoken to seem confident that the 0w-30 oil can handle the contamination and worst comes to worst I'd rather change the oil twice a year than replace the DPF biannually.
I've done a write up about the behavior of the DPF which might help a lot of people avoid these issues in future
