DPF cleaning across Bolton
Warning light on and worried you'll be told to buy a new filter? In Bolton we read the codes and the DPF's soot and pressure figures before doing anything, so the cause is clear from the start. A mobile clean costs £275 + VAT, with the visit to your home or workplace included.
What we read before cleaning in Bolton
Codes and soot readings
The technician connects to the vehicle and takes the fault codes, the soot load and the pressure across the filter.
You hear the verdict first
If it's soot, a clean will help, whereas ash, a cracked filter or a fault elsewhere is something we tell you about before going any further.
Cleaning and a forced regeneration
The solution loosens the soot, then a forced regeneration burns it out while the filter stays fitted.
Second set of readings
Codes are cleared and the figures rechecked, so you can compare before and after.
Why DPFs keep blocking
When a filter blocks more than once, there's usually something behind it.
Short journeys
The filter needs a spell of steady running to regenerate, and lots of short trips never give it that.
Faulty pressure sensor
If this sensor misreads, the ECU can't tell how full the filter is, so regenerations start too late or never.
EGR or injector faults
An engine making extra soot, perhaps through a sticking EGR valve or a worn injector, can overload the filter.
The wrong engine oil
Oils that aren't low-ash leave deposits that no regeneration can clear.
A diagnostic check at £100 + VAT can find the underlying cause if the readings hint at one.
Vans and work vehicles in Bolton
Delivery and trade vans doing short stop-start runs are tough on a DPF, as the exhaust seldom gets hot enough for long enough. We can clean them at your yard or depot in Bolton between jobs, and work through several in one go where that's possible.
Firms with a few diesel vans can set up a trade account to keep regular bookings straightforward.

Readings come before cleaning
The filter is only cleaned once the codes and figures show soot is the problem.
We tell you when cleaning won't work
If the filter is past the point a clean can help, you'll know that before we start.
How can I tell the DPF is the problem?
Limp mode and a flat engine can have other causes. Our readings confirm whether the filter is blocked before any work begins.
Why does my DPF keep blocking?
Usually because regenerations aren't finishing, through short trips, a sensor fault, EGR or injector problems, or the wrong oil. We'll mention anything we notice during the visit.
Can I have the DPF removed instead?
We offer a DPF delete, but only for vehicles used off-road or heading for export. Removing or disabling the filter on a road vehicle is illegal in the UK and shows up at the MOT. See Is DPF removal legal?
What happens if I ignore the DPF light?
Soot keeps building until limp mode sets in, and a badly neglected filter can end up past cleaning. That could mean a new DPF, which is often over £1,000 fitted.
