Overview
DPF and EGR Fault Diagnosis and Repair in Gwent
DPF and EGR systems clog or fail for reasons that are often found elsewhere in the engine: short journeys, a faulty sensor, an EGR valve, an injector or a turbo problem. Treating the symptom without finding the cause usually means the fault returns.
Our work is diagnosis, cleaning and repair, carried out in line with all current road-legal and driving safety standards. We do not remove or defeat DPF or EGR systems. Removal is illegal on road vehicles, and a car with its DPF removed fails the MOT.
Who it suits
- Diesel cars and vans with a DPF or EGR warning light
- Vehicles in limp mode
- Drivers whose filter will not regenerate
The process
How it works
- 01
Describe the fault
Tell us the warning lights, symptoms and recent driving, or request a quote.
- 02
Diagnosis
We find the underlying cause rather than clearing the warning.
- 03
Clean or repair
Cleaning of the filter or valve, or repair or replacement of the failing part.
- 04
Checked and tested
The system is checked after the work, so you know it is working.
What to expect
- The cause identified rather than the warning cleared
- A lawful, road-legal result
- Advice on avoiding the problem returning
Worth knowing
- A remap does not repair a failing DPF or EGR; the fault should be diagnosed and fixed first.
- Ignoring a DPF warning usually makes the repair more expensive.

Questions
DPF and EGR Fault Diagnosis and Repair: your questions
Can you remove my DPF or EGR?
No. It is illegal on road vehicles and we do not offer it. We diagnose, clean and repair instead.
Why does my DPF keep clogging?
Common causes are short journeys, sensor faults and injector or turbo problems. Diagnosis finds which applies to your car.
