Diesel Particulate Filter (DPF)            4-Stage Cleaning Service

It is important to understand why the DPF has blocked or failed, which fault codes are present and what effect these have on the DPF.

A thorough investigation must take place to ensure any other potential problems are removed:

• Short journeys & style of driving incompatible to automatic DPF regeneration
• Poor fuel quality
• Poorly operating or blocked injectors
• Faulty EGR valve (Exhaust Gas Recirculation)
• Incorrect engine oil
• Service intervals exceeded
• Split or damaged hoses
• Fault codes showing on the diagnostic equipment linked to DPF/Exhaust:

• Inject chemicals into system and clean DPF
• EGR system service
• Engine oil flush and replace oil/filter
• Carry out extensive road test and monitor DPF values and print test results
