This vehicle’s DPF housing had previously been modified after the filter was removed and then welded poorly. A suitable replacement was not available locally for this repair, while a new original filter was expensive, so the DPF was sent to Lithuania for restoration.

What did the housing inspection show?

The seams shown in the video were uneven and had not been properly finished or protected. During restoration, the seams were repaired and the assembly put back together. The work took longer because the earlier welds were poor.

What was completed and what was still planned?

At the time of the video, the restored DPF was ready to be installed. The next planned step was to fit it to the vehicle and check the particle readings. The video ends before the installation and measurement, so neither the test result nor a passed vehicle inspection is confirmed.

After DPF work, both the housing and joints and the filter’s operation in the vehicle’s exhaust system should be assessed. A tidy-looking housing alone does not confirm that the filter is working.
