Diesel Particulate Filter Refurbishment

What is a Diesel Particulate Filter? A Diesel Particulate Filter is a device fitted to a modern diesel vehicles exhaust system which filters particulate matter (PM) from exhaust gases.

DPF’s need to be emptied of trapped particulate matter regularly. This is done by a process called “regeneration” which involves burning the soot to gas at a very high temperature.

An underlying engine or fuel system fault, incorrect vehicle usage or lack of regeneration can cause an excessive build up of soot which subsequently affects vehicle performance and can lead to expensive repair costs. This has led to some vehicle owners removing the DPF entirely however, DPF removal has both social and legal implications.

“It is an offence under the Road vehicles (Construction and Use) Regulations (Regulation61a(3) to use a vehicle which has been modified in such a way that it no longer complies with the air pollutant emission standards it was designed to meet. Removal of the DPF will almost invariably contravene these requirements making the vehicle illegal for road use”

Historically DPF blockages have necessitated replacement of the unit; However Fuel Injection Services can now offer an alternative through our collaboration with Ceramex.


Refurbishment Procedure

Ceramex, international leaders in DPF refurbishment, have been refurbishing DPF’s for over fifteen years and have cleaned over 100,000 units. Using expertise gained in the commercial industry Ceramex have developed and patented the “Xpurge” procedure. The Xpurge process used by Ceramex is a tried and tested procedure that has been heavily scrutinised by vehicle manufacturers prior to being accepted as their preferred service provider. Great care should be taken when adopting a cleaning / refurbishment service in order not to cause any detrimental effect to the catalyst wash coat used by many OEMs.

Not only does the Xpurge process clean DPF filters it restore’s them to as-new levels of cleanliness. All filters are inspected prior to refurbishment and come complete with an inspection report showing air flow measurements before and after cleaning along with weight of ash removed. Ceramex offer the only service that comes with a 12 month or 12,000 mile free clean warranty.
