DPF Diagnostics & Forced Regeneration
Accurate live soot loading readings, differential pressure sensor diagnostics, and workshop static forced regeneration for blocked diesel particulate filters.
What we do
Why proper DPF diagnosis matters before forcing a regen
Triggering a forced regeneration on a filter blocked due to a faulty £45 differential pressure sensor will cause the filter to clog again within days.
We diagnose pressure sensor inputs, exhaust temperatures, and glow plug status first to ensure forced regeneration is safe and effective.
- Live Soot & Pressure Scan
- Sensor & EGR Component Check
- Static Forced Regeneration

Cause, regenerate, verify
DPF diagnostics for Coventry diesel drivers
A forced regeneration is only useful when the filter, sensors and engine conditions make it safe and worthwhile.
We check fault codes, soot loading, differential pressure, exhaust temperature data and the engine faults that may have stopped normal regeneration. Only then do we recommend workshop regeneration or another repair route.
After treatment, we verify the pressure readings again so you leave with evidence that the restriction has improved rather than a warning light that has simply been cleared.
- Pressure and sensor checks
- Safe regeneration decision
- Before-and-after verification

“Having been let down badly by previous garage , it’s been a joy to use Adam and his team! He as probably saved my car from near disaster, they have serviced and mot both my car and daughters . Can not recommend this garage enough. At last have a garage I can comfortably leave them to do their best and not”con” or “hoodwink”. Well done Motor Medics Coventry”

“You won’t find a more honest and reliable garage for electrical repairs than here. Adam, who I doubt with was extremely honest and most helpful. Highly recommended.”

Frequently asked questions
DPF Diagnostics FAQs
No. Removing or gutting a DPF is illegal for road use in the UK and results in an automatic MOT failure. We specialize in legal diagnostic repair, sensor replacement, and forced regeneration.
