Fusion DPF failure

My 2004 Ford Fusion diesel with 245725 km is showing reduced engine power and producing smoke when accelerating. I suspect it's a defective diesel particulate filter. Has anyone else had this?

Reduced power and smoke? Sounds like DPF issues. Has the engine light come on? What kind of fuel efficiency are you seeing now? High backpressure in the exhaust system can definitely cause those symptoms.

Yes, the engine light is on. Fuel efficiency has definitely dropped. What's the best way to confirm it's the DPF for sure before replacing it?

If the engine light is on and fuel efficiency is down alongside the smoke and power loss, a faulty DPF is highly probable. You'd need diagnostic tools to read the backpressure. It's best to take it to a workshop for a proper diagnosis before spending money on a new DPF.

Thanks for the advice. Took it to a shop, and they confirmed it was the DPF. Repair cost was 1550€. Appreciate the help!
