01 / NHC MOTORS
Inspect the vehicle before starting the clean
Removing deposits from the filter may lead to repeat work if an underlying problem remains. Vehicle-side inspection is therefore important before cleaning.
This XF received a smoke test. Engine-bay connections were checked and the DPF was removed for the work.
02 / NHC MOTORS
Off-car dry and wet cleaning
The removed filter was connected to the equipment for dry and wet cleaning. The photo below shows discharge from the filter during cleaning.

What to check before another clean
The clean was completed and the owner was advised that the vehicle would need monitoring. Any change during use can be compared against this record to direct further checks.
When DPF concerns recur, recent repairs and driving conditions also matter. Spending time investigating why the problem occurs helps avoid repeated cleaning or replacement costs.
Further action will be considered while monitoring symptoms and diagnostic results after cleaning.
