The owner of this Ford Transit with a Siemens SID211 control unit had bought the vehicle without a DPF and with previously modified software. A non-original particulate filter was installed later, and its operation needed to be reactivated in the control unit.

AutoChip wrote software configured for DPF operation and carried out a filter regeneration. According to the workshop, the regeneration cycle completed and the soot level decreased. The AdBlue system remained disabled in this configuration, so not all emissions systems were restored.

After programming, the engine ran smoothly, and no visible smoke was seen when the engine was revved while stationary. The fitted filter was non-original and had been installed about two weeks earlier. The video cannot establish its long-term performance, and continued reliability has not been confirmed.
