Auris DPF and Smoke on Acceleration

Hi, I have a 2008 Toyota Auris diesel, and I'm having some issues. The warning light in the speedometer is on, and there's smoke when accelerating. My local garage says the DPF won't regenerate, and they suspect it's the exhaust back pressure sensor. Anyone else had this problem? Any ideas?

I had similar symptoms with my Auris (diesel too). Turned out to be a faulty exhaust back pressure sensor. Is the garage sure that's the cause of your problem?

Thanks for the quick reply! They did some diagnostics and said the readings from the sensor were off. Just wondering if it definitely sounds like the back pressure sensor or could it be something else?

Based on your symptoms and the garage's diagnostics, a defective exhaust back pressure sensor seems the most probable cause. If they are sure with their diagnostics I would advise to replace it.

Thanks! I'll get them to replace the sensor. They quoted me 245€, so hopefully, that'll fix it. Appreciate the help!
