Diesel Particulate Filter Servicing

Experts in diesel particulate filter (DPF) servicing!

At JS Autocare we are experts in DPF (diesel particulate filter) regeneration (cleaning) servicerepairs & cleaning.

A diesel particulate filter (D.P.F.) is a device designed to remove soot or diesel particulate matter from the exhaust gas of your diesel engine.

DPF Filter cleaning is part of periodic maintenance and it must be done carefully to avoid damaging the filter.  Vehicles driven mainly at low speeds in urban stop start traffic can require periodic trips on the motorway at higher speeds to self clean out the DPF (DPF regeneration), but if you ignore warning lights,  continued driving ignoring the warning light may end up with you needing a Diesel Particulate filter replacement.

Our DPF cleaner service is available for any vehicles fitted with a DPF including: BMW, Alfa, Audi, Volkswagen, Skoda, Peugeot, Citroen, Mazda, Nissan, Jaguar, Landrover, Nissan, Vauxhall.

It’s a fact that emission control components on modern cars get clogged up and eventually fail to operate, resulting in under performance, reduced economy and risk to the longevity of your engine.

This can be caused by many factors including:

  • Poor driving practices and habits
  • Using the wrong type of oil for the specified vehicle
  • Clogging up of the intake system
  • Carbon from the EGR valve and inlet manifold passing through the engine and into the exhaust system.

Our 4-way intake engine cleaning service can be of great value to you, the point being that we clean from the source, not just the end point: your DPF filter.

Dirty oil can contribute to a DPF clogging, and if your DPF has been blocked for some time, carbon and soot can back up from your exhaust system and contaminate the oil.

Our service includes flushing your old engine oil, using B.G109 engine flush, and replacing the oil and oil filter, as well as the intake cleaner to clean the intake, combustion and exhaust, and a fule treatment which treats a full tank of fuel and continues to work its magic after we have performed the full service.

EGR valve cleaning

We also ensure your EGR valve is cleaned, as a clogged EGR valve is one of the main causes of a diesel engine smoking.  Exhaust gases mix with oil from the breather system to form an unhealthy ‘gunge’, which in turn clogs up the inlet manifold.  When this finds its way to the DPF filter, it creates a film over the front of it, clogging it solid, and eventually a blocked EGR valve will put the engine management light on, and most probably put your vehicle back in limp home mode.

Some modern EGR valves are very expensive and time consuming to replace, so where possible we would advice an ECU remap, and deleting the EGR software so we can blak the EGR valve off, eliminating the issues caused by a clogging EGR valve.

Remap of ECU software

We can organize a full remap of the ECU software to remove EGR and/or the DPF functions, and at no extra cost, you can choose from an economy tune, or a full performance tune of the ECU, both of which will gain you differing amounts of BHP, torque and fuel economy (MPG). Remaps from £170 (average cost)
