Diesel particulate filter diagnostics, regeneration and repair

A blocked diesel particulate filter causes warning lights, limp mode, poor MPG and expensive garage bills. We diagnose the real cause — sensors, differential pressure, injector or driving pattern — then carry out a forced regeneration or repair so the system works as it should.
Usually short, low-speed journeys that never let the filter reach regeneration temperature — or an underlying fault such as a leaking injector, faulty EGR or failed pressure sensor. We diagnose which it is before quoting any work.
DPF removal is illegal for vehicles used on UK roads and is an automatic MOT failure. We only offer legal diagnostics, regeneration and repair.
