V90 Diesel Power Loss and Smoke

I've got a 2016 Volvo V90 diesel. I've noticed less power and smoke from the exhaust when I accelerate. It's done 227537 km, so I'm thinking it's the DPF. I've tried cleaning and forced regeneration, but it's still happening. Could the backpressure mean I have to replace the filter?

I had similar issues with my V90 diesel. Reduced power and smoke usually points to DPF trouble. Have you tried monitoring the regeneration cycles? Is it attempting regeneration more often than usual?

How would you recommend I accurately monitor the regeneration cycles? Is there specific diagnostic equipment or software you found particularly helpful in determining whether the filter is beyond recovery and needs replacing?

I used a basic OBD2 scanner and a phone app to check the DPF soot level and regeneration frequency. Mine turned out to be too far gone, despite repeated regeneration attempts. A workshop visit is probably your next step, they should be able to confirm the fault with proper diagnostics.

I had a workshop perform diagnostics, and the DPF was defective and needed replacing. The entire repair, including the filter, cost 1550€ Thanks for guiding me.
