If you want your emissions equipment to last as long as it possibly can than you need to take care of everything feeds that filtering system. Just like any other filter, they will clog and be ruined faster if you run a lot of crap through them. Crap in this situation is unburnt fuel and soot from a heavy accelerator, poor programming, or an engine that can't properly run because its sensors and/or its feeding systems are not working correctly. Also if the engine is burning contaminates like oil or coolant. You need to make sure all these things are in tip top shape or all that dpf and scr canister is gonna do is plug with soot, oil, coolant and what ever mong the engine is throwing out. Egr system tune up is what its called around here. Watch the videos and read the mountainous info on here for performing this routine maintenance.

And lastly, the exhaust filter system (emissions system) has a service life. You'll only get so much use out of it before its gonna need replaced. Or the engine gets worn enough that keeping up with everything properly become impossible. To fix that you'll have to overhaul the engine or take steps to make the emissions not such a burden or even a thought.... that last choice could have good results if its done earlier.... either way, there is no magic genie in a can as Volvo8873 has stated.
