DPF Cleaning, Replacement & Removal Wirral & Liverpool
So what is a DPF? DPF stands for ‘diesel particulate filter’ and is located within the exhaust system which helps reduce the harmful emissions that comes from a diesel exhaust. A DPF essentially captures and stores exhaust soot and when the engine gets hot enough it burns them off.
1. Blocked with soot
2. Wrong engine Oil
3. Faulty Injectors
4. Oil Leaking from Turbo
5. EGR Valve faulty
1. Limp mode activated
2. Loss of power
3. Stuttering engine
4. DPF light on
5. Engine management light on
Why can a DPF get blocked?
If your journeys consist of short trips or the engine is kept in low revs then the soot will build up to the point that the DPF gets blocked and you see the warning light on your dashboard. If addressed early on it may be possible to clear it (consult your vehicle’s handbook) but it’s likely that you need to have it cleaned or replaced.
We see a large amount of burnt out and damaged DPFs and catalytic converters due to petrol
being added to diesel fuel, and also the wrong ratio to fuel additives i.e. one bottle of cleaner to a quarter of a tank of fuel; this super concentrates the additive and raises the temperature and melts and damages catalytic converters and DPFs .
Main causes of DPF problems
- Blocked with soot
- Wrong engine oil
- Faulty injectors
- Oil leaking from turbo
- Lack of servicing and maintenance
- Failed sensor preventing DPF regeneration
- EGR valves faulty and sticking open
- Exhaust gas temperature sensors faulty
Symptom of DPF problems
- Limp mode activated
- Loss of power
- Stuttering engine
- DPF light on
- Engine management light on
- White smoke from exhaust
Solutions to DPF problems
- Force a regeneration cycle
- Remove DPF filter and clean
- Remove DPF completely from exhaust
- Replace with new DPF filter
So what can Edge Performance do for you and your DPF?
As you can see there are several options to sort your DPF, and some of the methods of cleaning a DPF work on certain vehicles better than others. If your DPF is blocked due to an oil leak of some description you cannot recover a DPF without removing it.
At Edge Performance, a filter that is blocked due to an overaccumulation of soot can be removed and cleaned, as opposed to replacing it with a brand new unit, which other garages typically might do. A replacement DPF unit would cost well in excess of £1,300, whereas cleaning it will cost you in £180 to £400, depending on the vehicle.
We know that vehicles are detuned to work on any grade of fuel (especially outside Europe), but we can tune your vehicle so it doesn’t create as much soot and therefore won’t cause problems with the DPF in future. Emissions will also improve once your vehicle has been tuned/remapped.
Can I cause more damage to my DFP by trying to drive it when the warning light is on?
Some people will try to use DPF cleaner added to the fuel in an attempt to clear a blockage but this can sometimes burn the injector tips and cause the filter to melt and be destroyed.
Equally, trying to run your vehicle down the motorway when you have an issue with DPF, as is often advised, can often damage the turbo and engine.
What vehicle do we commonly see for DPF issues?
Vehicles commonly worked on include: Ford Transit 2 2.2 custom, Mercedes C220, Mercedes C250, Mercedes A200, Mercedes A220, Ford Focus 1.6, Ford C-MAX 1.6, Galaxy 2 litre diesel, Mondeo 2 litre diesel, Ford Kuga 2 litre, BMW 1 series & 3 series 2 litre, BMW 530d, BMW 353d, Mazda 3 & 6 2.2 litre, Honda CRV accord 2.2 litre, Jaguar XF 2.2 and 3 litre.
Will DPF removal affect my MOT?
From February 2014 we have to comply with legislation regarding emissions. Edge Performance will only offer DPF solutions for off road usage only. It is not illegal to remove a DPF from your car or van, however it is an offence under the Road Vehicles (Construction and Use) Regulations (regulation) 61A(3)1 to use a vehicle that has been modified in such a way that it no longer complies with the air pollutant emissions standards it was designed to meet. A missing DPF where one was fitted from February 2014 will result in an MOT failure.
