Malfunction of a 2019 Opel Crossland: Problems with DPF regeneration, increased fuel consumption and exhaust back pressure sensor

Hey guys, my 2019 Opel Crossland is showing some strange signs. When accelerating, the car emits black smoke from the exhaust and the check engine light is on. It also loses engine power, runs rough, has problems with DPF regeneration and fuel consumption is noticeably high. I think it may be the exhaust back pressure sensor. Has anyone ever had similar problems? How did you get it fixed in the workshop and what was your experience? I would be grateful for any advice.

Hey, I had a similar problem with my 2017 Opel Mokka. My car knowledge is rather low, but I always try to tackle it as best I can. At the garage, however, they told me that my DPF was severely overcharged. So in the end, the DPF in my car had to be replaced, which cost me 1325.0 euros. Of course, it itched, but afterwards the car ran like clockwork again and the black smoke was gone. So that could also be the problem with your Crossland. Could you perhaps give me more details about your car? What is your mileage and when was your last service? Maybe then I can help you even better.

Hi, thanks for your reply. My mileage is 170374 and my last inspection was recently. That's really annoying if it's the DPF... that costs a fortune. Hopefully it's something else, but thanks for the tip anyway!

Hey, no problem, that's what we're here for. Your mileage is pretty high, so there could be problems with the DPF. But have an error code scan carried out first. Maybe it really is the exhaust back pressure sensor, it could well be. Then it would probably be a bit cheaper. As you know, replacing parts on suspicion wouldn't make much sense. Let us know what comes out! Good luck with it!

Hey, thanks again for the advice. I'll take your advice and take the car in for a scan and see what comes up. Hopefully it's just the sensor. I will definitely keep you guys posted. Thanks for the help!

The "Check Engine" light can be triggered by a variety of issues, both minor and major. A simple first step is to check if your gas cap is loose or damaged, as this can cause the light to come on. If the cap is fine, it's best to get a diagnostic scan to identify the specific error code. This will give you a clearer idea of what the issue might be. It could be anything from a faulty sensor to a more serious engine problem. Given that your car has relatively low mileage and has been regularly serviced, it's important to get this checked out as soon as possible to prevent potential damage. Please update us on the situation after the diagnostic scan.
