How do I fix the code P2002 on my 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 is usually set because of issues like DPF failure, a leak in the exhaust system, and a faulty exhaust back pressure sensor. The symptoms of a P2002 code can range from an illuminated check engine light and reduced fuel efficiency to the engine entering limp mode.As you drive, the engine will adjust and do its best to clear out the problem. Typically, you can drive with a P2002 code, but if you want to be extra safe, you can talk to an expert to find out more about the code and what issues you might be experiencing.
What is the code P200200 on Audi a6?
They didn’t have the specialised diagnostic machines so didn’t know what the codes meant. After speaking to an Audi specialist garage on the phone they advised me the P200200 is ‘Particle trap efficiency below threshold, particle trap bank 1 efficiency low” amongst 20 other possible problems. Code P2000 is set once the efficiency of the bank 1 adsorber falls below design parameters. Some of the common causes of a P2000 code include a bad oxygen sensor, a faulty NOx sensor, and an overloaded NOx adsorber catalyst. Your check engine light will illuminate once this code is logged.
How to fix code P2002?
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 sensor is usually prone to failing when the soot loading of the DPF (Diesel Particulate Filter) is too high, which causes regeneration to stop. This leads to excessive soot accumulation, which clogs the diesel particulate filter, and can cause failure of the PM sensor.
