DPF Blockage Diagnosis
We use live data and pressure differential readings to accurately assess the level of DPF blockage and identify the underlying cause.
DPF System Support
Blocked filter. Power loss. Warning lights. We diagnose the root cause and get your diesel running cleanly again.
What We Do
Getting to the bottom of your DPF problems - properly.
A blocked or failing Diesel Particulate Filter is one of the most common and frustrating issues affecting modern diesel vehicles. Warning lights, reduced power, and forced regeneration cycles are all signs that something is not right.
At Tune It Scotland, we go beyond clearing fault codes - we use professional-grade diagnostic tools to identify exactly why your DPF is struggling, whether that is a blocked filter, a failed sensor, a fuelling issue, or a driving-habit problem. We then recommend and carry out the right fix, not just a temporary workaround.
Services Offered
Thorough DPF diagnosis and lasting solutions
From blocked filters to sensor failures, we cover every aspect of DPF diagnosis and resolution to restore your engine's performance and prevent recurring issues.
02
Forced DPF Regeneration
Where appropriate, we carry out a controlled, monitored forced regeneration to safely burn off accumulated soot and restore filter function.
03
DPF Sensor & Pressure Pipe Inspection
We check differential pressure sensors, temperature sensors, and associated pipework for faults that trigger false DPF warnings.
04
Root Cause Investigation
We identify contributing factors - short journeys, EGR faults, injector issues - that cause repeated DPF blockages and address them at the source.
05
Post-Treatment Verification
After any DPF work, we verify the system is operating correctly through live data monitoring before returning your vehicle.
How We Work
Diagnosis first. Fix second. No guesswork.
DPF problems are rarely straightforward. Our structured process ensures we understand exactly what is causing the issue before carrying out any work.
01
Diagnose
Full DPF system scan using OEM-level tools - reading live pressure data, temperature readings, and fault codes to build a complete picture.
02
Identify
We determine the root cause: whether it is driving habits, sensor failure, a mechanical fault, or a genuinely blocked filter requiring attention.
03
Resolve
We carry out the appropriate fix - regeneration, sensor replacement, or further investigation - with clear communication throughout.
04
Verify
Post-work data logging confirms the DPF system is operating within normal parameters before we sign off the job.
