Skoda Roomster Smoke and Warning Light

Good day. I am experiencing a problem with my 2006 Skoda Roomster, gasoline engine. A warning light has appeared on the speedometer, and the vehicle emits smoke upon acceleration. Furthermore, DPF regeneration is not possible. I suspect a defective exhaust back pressure sensor is the likely cause. Has anyone encountered a similar issue?

Whoa, sounds like a headache! I kinda had a similar thing with my Skoda Octavia (don’t remember the exact year). Warning light, bit of smoke, the whole shebang. Could be the pressure sensor, like you're thinking. Is the car struggling to accelerate, like it's being held back?

Thanks for the reply. Was it definitely the exhaust sensor on your Octavia? Did you also have issues with the vehicle emissions?

Yep, pretty sure it was the exhaust sensor. Although, I'm no expert. I remember they were talking about vehicle emissions being all over the place when they ran the diagnostics. Honestly, my advice would be to just get it to a workshop to confirm. Better safe than sorry, right?

I took the Roomster to a local mechanic. The exhaust back pressure sensor was indeed the culprit. Repair cost me 245€. Thanks for your input; it helped confirm my suspicions.
