Skoda Superb Diesel Engine Power Loss and Smoke

My 2020 Skoda Superb diesel is showing some weirdness. Mileage is pushing 120k km. I'm getting reduced engine power and seeing smoke when I accelerate hard. Suspecting the diesel particulate filter is knackered. Has anyone seen this before? Backpressure seems high too, based on what the ECU is reporting.

I had similar symptoms with my Superb. Reduced engine power and smoke suggest a potential exhaust system issue. Have you noticed any changes in fuel efficiency recently? It could be a sensor fault affecting the DPF's regeneration cycle.

Fuel efficiency has taken a hit, yeah. You reckon it's worth trying a DPF cleaning before looking at replacement?

Cleaning might offer a temporary fix, but if the DPF is genuinely defective, it'll likely clog up again quickly. Given the age and mileage, a replacement might be the only long-term solution. I'd advise getting it properly diagnosed at a workshop to confirm the extent of the damage.

Cheers for the advice. Turns out the DPF was toast alright. Had to get it replaced, cost me 1550€. Fuel efficiency seems back to normal now though.
