ANOTHER SUCCESSFUL DPF CLEAN!
This Citroën Berlingo DPF was brought to us by another local garage while they were working on the vehicle’s emissions system.
They asked us to clean the DPF as a precaution — and we think they made exactly the right call! 👍
Our pre-cleaning back-pressure reading was:
🔴 **33 mbar BEFORE**
After putting the DPF through the full Core Revival cleaning process, the post-cleaning reading was:
🟢 **9 mbar AFTER**
A great result and another successful clean! 💪
The video shows exactly what our cleaning process removes. Initially, you can see the black fluid, the soot being flushed from the DPF.
As the process continues, the fluid changes to a brown colour, this is the ash being removed.
It’s the accumulated soot and ash deposits inside the DPF that can contribute to increased restriction and back pressure, so removing these deposits can help restore the filter’s ability to flow.
Once cleaned, dried and tested, the DPF was issued with its Core Revival cleaning certificate and returned to the garage ready for refitting. ✅
Another DPF cleaned, tested and ready to go!
Core Revival — Restore. Clean. Test. Revive.
