DPF Problems Fixed Properly in Sheffield

DPF warning light on? Your diesel particulate filter traps soot and burns it off during longer, faster runs, a process called regeneration. Lots of short, slow journeys (most of real life, in other words) means the burn off never happens, the filter clogs and the light comes on. Ignore it long enough and the car goes into limp mode and the fix gets steadily dearer. Caught early, it is often a simple job.

The fix, in cost order

• Forced regeneration, from £120. Using our manufacturer level diagnostic equipment we command the burn off the car could not do itself. If the filter is not too far gone, this is the quick, affordable fix.
• If regeneration cannot save it, that means further diagnosis and, where needed, replacement. Additional cost, always quoted in writing before you commit, and we never fit a new filter without finding out why the old one blocked.
• Replacement is the last resort, and where quality matters: cheap DPFs cause repeat trouble. We quote genuine OEM and quality options side by side.

The important bit: why did it block?

A DPF that blocked is not always the villain. It is often the victim. Faulty EGR valves, tired injectors, a failed pressure sensor, the wrong engine oil or simply the wrong car for short journey life all cause repeat blockages. Clean the filter without finding the cause and you will be back in three months. Our diagnosis covers the why, not just the what. That is the difference between fixing it and renting a fix.

What we will not do: DPF removal

You may have seen DPF deletes offered. We do not do them, ever. Removing a DPF from a road car is illegal, it is an automatic MOT failure, and it can invalidate your insurance, which makes a £300 solution a very expensive liability wearing a disguise. Anyone offering it is transferring their problem to you. We will fix the actual fault instead, legally, and it usually costs less than people fear.
