Original wording in English

Check engine light with fault code P3005CA in MRD1 (CDI) Complaint The check engine light is on, with a possiblility in a reduction of power and the presence of soot in the exhaust system. Fault code P3005CA: The diesel particulate filter efficiency is insufficient. Additional information: Additional fault codes may be present, related to the Diesel Particulate Filter (DPF) system or the Exhaust Gas Recirculation (EGR) system. Cause This fault code sets due to the following factors: 1. Damage to the Diesel Particulate Filter (DPF) unit. 2. The N74 (Soot Particulate Sensor Control Unit) identifies soot or debris located downstream of the SCR Catalyst (underbody). Remedy Note: The guided tests for fault code P3005CA have been revised in the XENTRY unit. It is important to complete these guided tests thoroughly. TIPS cases are NO longer required unless there is an absence of soot at the outlet of the Diesel Particulate Filter (DPF) unit. If there are any other fault codes present for component 'N74 (Soot Particulate Sensor Control Unit)', process these first. 1. Damage to the Diesel Particulate Filter (DPF) unit.
• Complete the XENTRY guided tests:
• Check the Exhaust system for leaks - Perform a visual inspection of the exhaust system from the Combustion Engine to Diesel Particulate Filter (DPF). Verify that there are no external damages and that all clamps and sensors are installed and leak-free.
• Check component 'Exhaust pipe and Filter screen of Exhaust Gas Recirculation (low pressure)' for carbon fouling. If no soot is present at the Tailpipe outlet, recommended to separate the exhaust pipe downstream of the Diesel Particulate Filter (DPF) at the outlet to inspect.
