Black smoke and loss of power in Toyota Auris 2014: Possible defect in the exhaust back pressure sensor?

Hi, I had a similar problem with my Toyota Yaris from 2011. The DPF was also heavily overloaded and the symptoms you describe, such as black smoke and a juddering engine, sounded very familiar to me. A really nasty story. My garage did a complete DPF cleaning at the time. To be honest, I was a bit worried at first that the whole thing would somehow ruin my car, but well, it turned out to be quite necessary. And a DPF problem like this is usually not an isolated case due to regeneration errors. In my example, the exhaust back pressure sensor also had to be replaced and the turbocharger system was thoroughly checked. Keep your ears to the ground and let us know what it was in the end. See you then,

Hey, thanks for your quick reply! Your experience clears things up and also reassures me a bit. It's really stupid that something like this can happen. Do you remember what you paid for the whole repair? And have you noticed any other problems since then? Regards,

Hey, no problem, always happy to help! The cleaning of the DPF cost me €1325. Of course, that was quite a lot of money, but it was definitely worth it, the car ran like a champ again afterwards. We also had the exhaust back pressure sensor replaced, and this fault has since been rectified. And I haven't noticed any further problems since the visit to the workshop. So the repair really seems to have done the trick. See you then,

Hey, wow, that's a lot of money, but if it helps, then it's worth it. I will definitely look for a garage near me that specializes in Toyotas. It's great that you've been able to drive without any problems since then. Your experience gives me hope that I can find a solution too. Thanks for your help and advice! See you then,
