DPF Cleaning and Repairs in Tyne and Wear

A diesel particulate filter, or DPF, traps soot from a diesel engine's exhaust. It is meant to clear itself by burning that soot off at high temperature, a process called regeneration.

Regeneration needs the right conditions. Short, slow journeys often prevent it, and over time the filter clogs. At Banks of the Tyne in Hebburn we offer DPF diagnostics, cleaning and repairs for Tyne and Wear drivers.

Signs your DPF needs attention

The usual first sign is a dashboard warning, often a filter symbol or the engine management light. You may also notice the car feeling flat, the fans running after you switch off, or fuel use creeping up.

• DPF or engine warning light
• Reduced power or limp mode
• Frequent regeneration with the engine running hot
• Smoke from the exhaust
• Oily smell or rising oil level

What the work involves

We start by reading the fault codes and checking live data, including pressure readings across the filter, to see whether it is truly blocked or a sensor is misleading the car. Then we decide between cleaning, a forced regeneration or replacement.

Cleaning is not always possible. If the filter is cracked, melted or heavily contaminated with ash or oil, cleaning may not restore it. We tell you what we find rather than guess.

Why it blocked in the first place

Repeated short trips are the common culprit, but not the only one. A faulty injector, a leaking turbo, a failed EGR valve or a bad sensor can all cause excess soot, and a clean filter will simply clog again if they are left alone.

Cost depends on the vehicle, the level of blockage, whether other parts are involved and whether cleaning or replacement is needed. We explain this at the estimate.

What not to do

Do not ignore the light and keep doing short journeys. Do not remove or hollow out a filter. Taking out a DPF can lead to an MOT failure and may break the law, so check the current rules before listening to anyone who suggests it.

If the car loses power or the warning is accompanied by overheating or smoke, stop somewhere safe and get it checked.
