Exhaust smell and warning light despite new parts on Opel Astra Diesel

I own a 2019 Opel Astra with a diesel engine and 140,554 km on the odometer. I'm experiencing the following problems: There's a strong exhaust odor, and even though the DPF, differential pressure sensor, and NOx sensor have been replaced, the warning light came on again after about 250 kilometers (error code P2002). While driving, I've also noticed an exhaust odor inside the car, and the tailpipe looks quite black. What could be the problem? Could it be the EGR valve? There's no loss of power, and fuel consumption is also not higher. Has anyone had similar experiences or tips for solving this problem?

Check for any exhaust leaks, especially around the exhaust manifold and connections, as these could cause exhaust fumes to enter the cabin and affect DPF performance. If you find any leaks, have them repaired promptly. Let me know if this resolves the issue or if you need further assistance.
