Skoda Karoq Diesel Particulate Filter Warning

I am writing about an issue I am experiencing with my 2020 Skoda Karoq, which has a diesel engine. The vehicle currently has 154294 km. A warning light has appeared in the speedometer, indicating a problem with the diesel particulate filter. Symptoms include reduced engine power, smoke upon acceleration, and a strong exhaust smell. After some research, I suspect the issue may be a defective exhaust back pressure sensor. Is this a plausible diagnosis, given the symptoms?

Reduced power and smoke? Sounds familiar. I had similar DPF issues with my Karoq. Have you checked the exhaust back pressure sensor? Is the warning light constantly on?

You mentioned you had similar DPF issues. Was the exhaust back pressure sensor the cause in your case as well? Was the reduced power significant?

Yes, the exhaust back pressure sensor was the problem. The reduced power was quite noticeable, especially uphill. If you suspect the sensor, I would suggest visiting a workshop to confirm. It is likely the source of your DPF issues.

I appreciate the assistance. It turns out the exhaust back pressure sensor was indeed the culprit. The repair cost me 245€. Now the car runs as expected. Thank you again.
