Skoda Scala Diesel Particulate Filter Issue

Reduced engine power and smoke? Sounds like DPF backpressure. I had a similar issue with my old Peugeot. Have you tried any DPF cleaning solutions?

DPF cleaning? I've seen some kits online. Did it work for you, and for how long? I'm trying to avoid a complete diesel filter replacement if possible.

The DPF cleaning helped temporarily on the Peugeot, maybe a month or two. But the underlying problem returned quickly. Given your symptoms, especially the smoke, I'd suggest getting it checked at a workshop. Sounds like filter replacement might be necessary.

Appreciate the insight. Turns out the diesel particulate filter was indeed defective. Had to bite the bullet and get a filter replacement. Cost me 1550€. Hopefully, my fuel efficiency will return to normal now.
