Cascada DPF Failure: Exhaust Pressure Sensor Alert

Had a similar issue with my 2012 Insignia diesel last year. Have some experience working on cars and diagnosing basic issues, but this one needed professional help. The symptoms matched exactly, warning lights, smoke during acceleration, and DPF regeneration problems. The engine performance was notably affected too. After researching emission control problems, I suspected the exhaust back pressure sensor, but wanted a proper diagnosis. Took it to my regular workshop where they confirmed the pressure sensor was faulty using diagnostic equipment. They checked the entire emission control system to ensure no other components were affected. The repair involved replacing the defective sensor and clearing the error codes. Total cost was 245 for parts and labor, which seems standard for this type of car maintenance. The fix completely resolved all symptoms, no more warning lights, proper DPF regeneration, and restored engine performance. What exact model year is your Cascada and how many miles has it done? Also, have you noticed any other symptoms like reduced power or unusual engine sounds? This information would help determine if your situation is similar to what I experienced. Important to note that delaying pressure sensor replacement can lead to more serious DPF issues and costlier repairs down the line.

Thanks for sharing your experience. My Cascada has 100995 KM and was last serviced 3 months ago. No reduced power or unusual sounds noticed yet. The vehicle emissions warning and DPF light are my main concerns. Your repair cost sounds reasonable compared to what I expected for vehicle diagnostics and sensor replacement. Your mention of checking the entire exhaust system is helpful, will make sure the shop does a complete inspection when I take it in. Good point about not delaying the repair, as I want to avoid any additional back pressure issues that could damage other components.

Thanks for the update on your Cascada. That mileage is actually quite similar to when my Insignia started showing these symptoms. Having gone through this repair, I can confirm the exhaust system inspection is crucial, my mechanic found the pressure sensor issue was isolated, but its worth having them verify no other components are affected. From my follow-up experience after the repair, the vehicle emissions and DPF systems have worked flawlessly. The engine performance returned to normal immediately after the sensor replacement. Just make sure they use OE quality parts for the sensor, learned this matters a lot for proper system function. Good call on addressing this promptly. After my repair, I noticed better fuel economy too, which was an unexpected bonus. The car maintenance schedule now includes regular checks of the exhaust back pressure readings during servicing to catch any potential issues early. Let us know how the repair goes, always helpful for others who might face similar problems with these models.

Thanks for all the input regarding the exhaust sensor issues. Just wanted to close the loop and share that I took my Cascada in yesterday. The diagnosis matched exactly what you described, faulty exhaust pressure sensor causing the DPF regeneration problems. The repair cost came to 260 with parts and labor, slightly more than yours but still reasonable. They did a full vehicle diagnostics check and inspected the entire emission control system as suggested. No other issues were found, which was a relief. All warning lights are now off and the DPF is cycling normally. The smoke under acceleration has completely cleared up. The shop recommended adding emission system checks to my regular car maintenance schedule, which makes sense given the mileage. Really appreciate the detailed advice about getting it fixed promptly. Knowing someone else had successfully resolved the same issue made me more confident about the repair decision. Will definitely keep monitoring the exhaust system performance going forward.
