Skoda Yeti Diesel power loss and smoke

I am at my wit's end with my Skoda Yeti (2010, Diesel). It's got about 89800 km on the clock. Lately, I've noticed a significant reduction in engine power, and it's started belching out smoke when I accelerate even gently. I suspect it's the dreaded diesel particulate filter (DPF), but I'm not entirely sure. Any ideas what to do? It has been suggested to me that the DPF may be defective. Has anyone experienced similar symptoms and what can I do before I bring it to a workshop?

Sounds like a classic DPF issue. I had something similar with my Yeti, though I don't remember the build year. Have you checked the backpressure sensor? A sensor fault can trigger similar symptoms, even if the DPF isn't completely blocked. Also, did you try a forced regeneration using a diagnostic tool?

I haven't checked the backpressure sensor, honestly I wouldn't know where to start. And no, I didn't try a forced regeneration. What exactly does that do, and is it something I could do myself, or is it best left to the professionals?

A forced regeneration basically burns off the soot inside the DPF at a higher temperature than normal. It requires a diagnostic tool to initiate and monitor the process. Given the smoke and power loss, the DPF is likely beyond cleaning. You're probably looking at replacement, unfortunately. I'd recommend taking it to a workshop for a vehicle inspection to confirm the DPF issue and get a quote.

Thank you so much for your help! I took it to a workshop, and after a vehicle inspection, they confirmed it was a defective DPF. I ended up having to replace the whole thing, cost me about 1550€. Ouch! But at least the car is running smoothly now.
