Exhaust System Solutions
DPF & EGR Solutions
If your DPF or EGR system is giving trouble — warning lights, limp mode, rough idling, we can help. These systems are known for causing repeat problems, especially on older diesels.
We offer cleaning, repair, or alternative solutions depending on what’s wrong and how the vehicle is used. For cars that keep failing, a long-term fix may be the better option.
We’ll inspect the issue, explain your options clearly, and carry out the work properly.
*Any DPF or EGR removal is offered for "off-road or motorsport use only"
ECO Tuning FAQs
Frequently Asked Questions
What’s the difference between a DPF and an EGR valve?
The DPF traps soot in the exhaust. The EGR valve re-circulates gases to reduce emissions.
Both can clog or fail and cause major issues if left.
Why are they always causing problems?
They’re sensitive systems that don’t suit short journeys or older engines.
Even fully working ones can cause performance issues over time.
Can it damage my engine?
A blocked DPF can — it puts stress on the engine and turbo. Fixing it properly helps prevent long-term damage.
Why is my DPF light on?
It usually means the filter is full or something has stopped it regenerating. Ignoring it can cause major problems.
Can you remove the DPF?
We offer solutions depending on the vehicle and use case. Some options may only be suitable for off-road or non-road-legal use.
We’ll explain what’s possible.
What’s the difference between cleaning and deleting?
Cleaning restores the DPF to working order.
A more permanent option may be available if the issue keeps returning — especially for older vehicles.
Do I need to replace it?
Not always. Many DPF issues can be sorted without buying a new filter.
We’ll inspect it first and let you know the best option.
Will this affect my NCT?
It can. If emissions systems are removed or not working properly, the car might not pass. We’ll give you honest advice before any work is done.
