VW Touran DPF Regeneration & Exhaust Sensor Issues

After experiencing similar exhaust system issues with my VW Tiguan 2013 diesel, the symptoms you describe strongly indicate a faulty exhaust back pressure sensor. The engine performance problems and DPF regeneration issues match exactly what I encountered. In my case, the vehicle emissions system was struggling due to incorrect readings from the defective sensor. The exhaust sensor failure prevented proper monitoring of back pressure, leading to incomplete DPF regeneration cycles. During the repair process, the diagnostic tests confirmed the sensor malfunction. The fix required replacing the exhaust back pressure sensor and clearing the engine control module codes. The mechanic also performed a forced DPF regeneration to ensure the system was working correctly. This is a serious issue that needs prompt attention, as continuing to drive with a malfunctioning sensor can lead to more severe exhaust system damage and potentially complete DPF failure. The repair process was straightforward once properly diagnosed. After replacement, all symptoms resolved, including the check engine light and smoke issues. Regular maintenance since then has kept the exhaust system functioning properly.

Thanks for sharing your experience with the exhaust sensor replacement. I had almost identical emission control problems with my Touran last year. The mechanic explained that these sensors often fail around the mileage you mentioned, which can really impact engine performance. Can you remember roughly how much you paid for the repair? Also curious if you have had any other exhaust system issues since getting it fixed? Wondering if I should prepare for any related problems down the line.

The exhaust back pressure sensor repair on my Tiguan cost 245€ all in, which included the diagnostic work and labor. The auto repair shop completed everything in one day, and it was money well spent considering how critical this component is for proper emission control. Since fixing the faulty sensor, the exhaust system has been working flawlessly. The engine performance improved immediately, and the DPF regeneration cycles now complete normally. No more check engine lights or smoke issues have occurred in the past year. Regular maintenance has kept everything running smoothly, but its worth monitoring the exhaust sensor readings during routine servicing to catch any potential issues early. The mechanic mentioned these sensors typically last another 80000-100000km after replacement when properly maintained. The repair eliminated all the back pressure related problems, and the emissions system now functions exactly as it should. The investment in fixing the sensor definitely prevented more expensive exhaust system repairs later.

Thanks everyone for the helpful replies. Just wanted to share how my repair went. I took my Touran to a different auto repair shop this time, and the experience was much better. The mechanic confirmed the exhaust back pressure sensor was indeed the culprit after running thorough vehicle diagnostics. The total repair came to 290€, which included the new sensor, labor, and a complete emission control system check. They had the car ready in about 4 hours. The exhaust system is now working perfectly, no more smoke, check engine light is off, and the DPF regeneration cycles are running normally. Car maintenance on these diesel engines can be tricky, but finding a mechanic who really understands the emission control systems made all the difference. The technician also showed me the old sensor and explained how it had failed, which helped me understand the issue better. After driving for a few weeks now, the engine performance is noticeably better, and I havent seen any smoke from the exhaust during acceleration. Definitely worth getting this fixed properly rather than letting it develop into a bigger problem.
