A method is provided for operating a Diesel engine system. The diesel engine system includes, but is not limited to a Diesel engine, an intake line for feeding fresh induction air into the Diesel engine, an exhaust line for discharging exhaust gas from the Diesel engine, a Diesel Particulate Filter DPF located in the exhaust line, and an Exhaust Gas Recirculation EGR system for routing back exhaust gas into the Diesel engine. The EGR system includes, but is not limited to a long EGR route LRE that gets exhaust gas from the exhaust line downstream the DPF. The method includes, but is not limited to setting a soot threshold (Sth) for the amount of soot flowing into the LRE, determining the actual amount of soot (Saa) flowing into the LRE, and activating a LRE protection routine, if the actual amount of soot (Saa) exceeds the soot threshold (Sth).
