Thanks, reassuring to hear someone else has experienced the same issue. How did you pinpoint the exhaust back pressure sensor? Did you run diagnostic tests, or was it visually apparent? How to check for DPF issues?

A diagnostic scan at the workshop indicated that the exhaust back pressure sensor was malfunctioning. Given the symptoms you describe, it's highly probable that you're facing the same issue. I would suggest taking your Modus to a trusted workshop for a diagnosis.

Following the advice, I took the car to a local workshop, and diagnostics identified the exhaust back pressure sensor as defective. Replaced the sensor, and the total repair cost was 245€. Thanks for your help!

I also own a Renault Modus diesel, and your description sounds very familiar. I recall experiencing identical symptoms – the reduced engine power and the smoke were particularly alarming. In my case, these issues were indeed linked to the DPF. Have you checked the exhaust back pressure sensor?
