Diesel Particulate Filter Specialists

Experts in diesel particulate filter (DPF) care

At White Hill Garage 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 cleaning is part of periodic maintenance and it must be done carefully to avoid damaging the filter.  Vehicles driven exclusively at low speeds in urban traffic can require periodic trips at higher speeds to clean out the DPF, but you ignore warning lights at your peril: continued operation may end up with you needing a replacement.

Our DPF care 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 of life that emission control components on modern cars get clogged up and eventually fail to operate, resulting in underperformance, reduced economy and risk to the integrity 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.

Unlike other companies, as part of our DPF removal service we treat the causes and not just the issue of a blocked DPF filter.


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.

We can now remap your vehicle to ignore the DPF filter, often called DPF delete, and remove the filtration from the exhaust so that you will never experience DPF problems in the future.

Dirty oil can contribute to 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.

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.

Remap of ECU software

We can organize a full and proper remap of the ECU software to remove 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).

We offer DPF removal from around £350, but call us on 01257 367 839 for a highly competitive quote for the exact repair work you require.  It will cost far less than going to the main dealer.
