DPF Diagnostics & Forced Regeneration
Accurate live soot loading readings, differential pressure sensor diagnostics, and workshop static forced regeneration for blocked diesel particulate filters.
Measure the restriction. Find the cause. Regenerate only when safe.
DIAGNOSIS BEFORE REGEN
A warning light is data, not permission to force a regeneration.
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 readings beat guesswork.
SERVICE COVERAGE
What our DPF diagnostic service includes
Complete diesel particulate filter investigation.
Live Soot & Pressure Scan
Accurate mbar differential pressure measurements before and after filter.
Sensor & EGR Component Check
Verifying exhaust gas temperature sensors, glow plug relay, and EGR valve.
Static Forced Regeneration
ECU-driven thermal soot burn in controlled workshop conditions.
FROM BOOKING TO VERDICT
How DPF booking works
We prove the cause first, then confirm the pressure drop afterwards.
- STEP 1
Book diagnostic check
Bring your diesel vehicle to our Coventry garage for initial OBD pressure scanning.
- STEP 2
Live testing & forced regen
We check sensor integrity and execute a static forced regeneration if preconditions are safe.
- STEP 3
Post-test & verification
We verify pressure drops, clear ECU fault codes, and road test.
CLEAR PRICE / CLEAR NEXT STEP
DPF Diagnostics & Forced Regeneration

COMMON QUESTIONS
DPF Diagnostics FAQs
Still unsure whether this is the right service?
Call 024 7531 1911Do you offer DPF removal or gutting services?
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.
Can every blocked DPF be saved with forced regeneration?
If soot loading exceeds critical safety thresholds or if the filter is ash-saturated (permanent chemical byproduct), forced regeneration may be unsafe or ineffective. We test live values first and advise you honestly.
