DPF Diagnostics and Fault Finding
DPF warning lights are often symptoms, not root causes. We diagnose the system before recommending cleaning, regeneration or ECU work.
What We Check
- Soot load and ash load data where supported
- Differential pressure readings
- Exhaust temperature sensor values
- Failed regeneration history
- Related EGR, boost and fuelling issues
Why Diagnosis Matters
Forced regeneration or cleaning may not last if the vehicle still has a faulty sensor, short-journey driving pattern, thermostat issue or failed regeneration logic.
Off-road and competition use only. Options such as DPF, EGR, AdBlue/SCR, GPF and catalytic converter removal, fault code (DTC) disabling, speed limiter removal and pops & bangs are for off-road, motorsport or competition use only. They are not legal on public roads in the UK. Removing a DPF is an MOT failure, with fines of up to £1,000 for a car and £2,500 for a van (GOV.UK). You are responsible for the legal use of your vehicle.
