How to fix P2002 audi?
Most often, trouble code p2002 is a result of a clogged dpf. You’ll simply need to burn off some of the soot to clear the filter and restore its functionality. Of course, there are many other reasons that this error code could be triggered. A damaged sensor, air leak, or damaged dpf could all be causes. The p2002 code indicates a dpf below threshold efficiency, often due to soot buildup or sensor faults. Cleaning the dpf and replacing the differential pressure and soot sensors are common fixes. If the code returns, inspect for exhaust leaks, wiring issues, or ecu faults.
