Engine Management & Performance Diagnostics
Find and Fix Engine Light Warnings Fast
- Read and clear engine fault codes
- Analyse live engine data for misfires, sensor faults, turbo issues, air/fuel ratio, fuel injectors, and more
- Reset service and maintenance lights
- Provide a clear, jargon-free report so you understand exactly what’s wrong and what to do next
Modern diesels rely on DPFs to trap soot and meet emissions targets. DPFs often block up due to short journeys, low-quality diesel, or engine faults.
What goes wrong:
- Frequent short trips in Coventry towns mean the DPF doesn’t get hot enough to regenerate
- Bad fuel and poor maintenance cause more soot
- Faulty sensors, EGR or injectors can worsen DPF clogging
Our DPF Services:
- Soot and ash level checks
- Forced DPF regeneration (to clear blockages)
- Fault code reading and reset
- Sensor and pressure pipe testing
- Advice on how to avoid future problems
How to keep your DPF healthy:
- Take longer drives at motorway speeds
- Use only high-quality diesel and correct low SAPS oil
- Fix warning lights right away
- Add a diesel fuel additive every 2,000 miles, especially if you drive short distances
AdBlue & Emissions System Experts
SCR (AdBlue) Diagnostics & Maintenance
SCR systems with AdBlue help your vehicle meet modern emission laws, but they are sensitive to low fluid, sensor faults, and contamination.
Common SCR/AdBlue problems:
- Low AdBlue or poor quality fluid
- Blocked or failing injectors
- Sensor and pump faults
- Warning lights, “no restart” messages, or restricted power
Our SCR/AdBlue Services:
- Full system scans and live data checks
- Injector and sensor diagnostics
- AdBlue warning resets
- Clear, honest advice on keeping your SCR system in top shape
How to keep SCR/AdBlue working:
- Always use the right grade AdBlue and keep topped up
- Book a diagnostics check if you see any warning lights
- Store AdBlue in a cool, dry place and avoid contamination
EGR Valve Diagnostics & Cleaning
Cleaner Engines, Lower Emissions
Blocked EGR valves cause rough running, higher emissions, and warning lights—common in vehicles doing mostly city miles.
- Test EGR valve operation and sensors
- Live testing and adaptation reset
- Advice on prevention: use an EGR cleaner every 2,000 miles and take regular longer drives
