Skoda Praktik diesel smoke and warning light

I am experiencing issues with my 2007 Skoda Praktik diesel, mileage at 233034 km. A warning light appeared in the speedometer, and there's noticeable smoke when accelerating. I am unable to regenerate the DPF. Could a defective exhaust back pressure sensor cause these problems?

Summary of the thread

A 2007 Skoda Praktik diesel was experiencing issues with a warning light and noticeable smoke during acceleration, along with an inability to regenerate the DPF. The problem was suspected to be caused by a defective exhaust back pressure sensor. After replacing the faulty sensor at a workshop, the warning light disappeared, and the smoke issue was resolved.

Sounds familiar. Does it struggle with DPF regeneration too? I had similar symptoms with my Praktik. Check the exhaust sensor. It is a common problem.

Is it difficult to replace the back pressure sensor? Where is it located exactly?

I wouldn't say it is easy. Access is tight. You will need specific tools. Best take it to a workshop. It will save you a headache. But could be the exhaust sensor.

Appreciate the help. Indeed, the exhaust back pressure sensor was faulty. Had it replaced at a workshop for 245€. Warning light is gone, and the smoke is no longer an issue.
