Trying to remove all of these codes and patches is no simple task, as the additional codes are located elsewhere in the ECU.
Vehicle owners are experiencing problems with the DPF removal ECU software, and although initially the software would seem to work, around 100 miles later, the DPF light would return.
This causes the vehicle to try and regenerate, which often places it into "limp-home" mode, and reduce the engine power. Be warned, this will cause damage to engines!
The electronic engine controls monitor EGR sensors and other inputs to determine diesel particulate filter (DPF) system regeneration needs. As a normal course of operation, the electronic controls will trigger an automatic regeneration of the DPF removal system. Additionally, the system can notify the machine operator to manually regenerate the DPF system occasionally when the soot load in the DPF exceeds the range defined for automatic regeneration.
ReplyDeleteTrue, the automatic/periodic regeneration is the very reason why fitting an emulator to bypass the DPF system is such a hit and miss operation. Emulators, similar to incorrect ECU Software modification, often cause the engine management system to continue regeneration operations which decreases the MPG and dilutes the engine oil which in turn significantly increases the wear and tear of the engine components, especially the turbocharge. If replacing the filter seems like too expensive an operation or if you cannot source an aftermarket replacement for your vehicle, then professional re-programming of the ECUs software is the only reliable option.
