🚨 DPF FAULT? DON’T ASSUME IT JUST NEEDS CLEANING! 🚨
The number of vehicles we’ve seen lately with split boost pipes, leaking intercoolers or cracked inlet manifolds is unbelievable.
We regularly receive phone calls saying:
🗣️ “My DPF needs cleaning.”
But once we carry out proper diagnostics and connect the vehicle to our smoke-testing machine, the real problem is often a boost leak.
A boost leak can cause:
❌ Loss of power
❌ Excessive smoke and soot
❌ Poor fuel economy
❌ Engine-management lights
❌ DPF and EGR-related fault codes
❌ Frequent or failed regenerations
❌ Limp mode
Cleaning the DPF without fixing the underlying fault means the problem will usually return.
At CNS we diagnose the cause instead of simply replacing or cleaning parts unnecessarily. With full diagnostic equipment and smoke-testing facilities at our unit, we can identify leaks that may otherwise be missed.
