I've just reviewed my manual for that P0410 code and the quickest diagnosis can be done by the dealer with the Volvo scan tool. It can disect the OBD-II codes into much finer EFI codes that lead to dignostic procedures in the manual. Get to a qualified well equiped dealer or get the manual TP2321201 and follow the procedures assuming various starting points as would be indicated by one of the Volvo EFI codes.

I didn't follow all the diagnostic branches but in all of the ones I followed NONE pointed to the CAT. Most involve leaks in hoses, a bad/stuck PAIR valve (The valve over the exhaust manifold), wireing between the ECU and the solenoid, bad solenoid but your's is new, etc.

Don't replace any more expensive parts without a diagnosis! You will waste a lot of $.$$

The ECU is a 32 bit processor with a lot of diagnostic information and engineering time represented. Make use of it, please.
