Nissan Crew DPF failure

My 2006 Nissan Crew diesel has a persistent issue. 228460 km on the odometer. Significant reduction in engine power and smoke during acceleration. Diagnostics suggest a defective diesel particulate filter. I tried a forced regeneration cycle, but the symptoms persist. Could a faulty sensor contribute, or is DPF cleaning warranted?

A 2006 Nissan Crew diesel is experiencing reduced engine power and smoke during acceleration, with diagnostics indicating a defective diesel particulate filter (DPF). Despite attempting a forced regeneration cycle, the issue persists. Possible causes include a faulty sensor or the need for DPF cleaning. Given the vehicle's mileage and a 15% drop in fuel efficiency, a workshop assessment is recommended to determine if cleaning or replacement is necessary.

Reduced engine power and smoke point towards DPF issues. Backpressure readings would confirm it. Has fuel efficiency dropped as well?

Yes, fuel efficiency has declined, approximately 15%. If backpressure is elevated, does this indicate irreparable damage to the DPF, or could cleaning still prove effective?

Fuel efficiency drop seals it. Cleaning might work, but with that mileage, a replacement is likely needed. A workshop should confirm the state and advise.

Thanks. I will consult a qualified workshop for a comprehensive assessment and proceed with repairs. I suspect the repair cost will be around 1550€.
