Specialist Mobile Service
Is your car or van suffering from an EGR valve fault in Horsham? At VMAX Tuning, we specialise in permanent EGR solutions.
Instead of temporary chemical cleans, we offer a mobile EGR blanking and delete service that comes directly to your location. Whether you are at home in an RH12 or RH13 postcode, or at your business premises, our technicians can resolve your EGR issues.
This process involves electronically disabling the EGR valve and fitting a blanking plate, preventing exhaust gases from being recirculated. This stops carbon buildup, restores performance, and improves fuel efficiency.
We fix 90 percent of all cars and vans with a professional, reliable service.
Fixed at your door, not ours
Home driveway, business yard, office car park or trade unit. Our technicians arrive with dealer grade equipment and complete the work on site.
No recovery truck, no courtesy car juggling.
Remove DPF, blank EGR, delete AdBlue
Three problem areas that cost diesel owners the most. We handle all three properly, with backup files saved for life and clear honest advice on what your vehicle actually needs.
Local Context
Why Horsham drivers book us
As a Horsham based business ourselves, we know the local roads well. The stop start traffic around the one way system and the short trips into town for shopping or the commute to the station can be tough on a diesel engine's EGR system.
Many of our customers are local traders and commuters who rely on their vehicles daily. A van used for jobs around town or a car for the A24 run up to the M25 can quickly develop carbon buildup in the EGR valve from this type of driving.
An EGR fault often starts with a warning light on the dashboard, leading to poor performance and limp mode. Our mobile service is designed for maximum convenience, reaching you anywhere in Horsham.
Local Patterns
Why EGR faults hit Horsham hardest
The driving patterns in and around Horsham contribute significantly to EGR valve faults. Short journeys, like dropping the kids at school or popping to a supermarket, mean the engine rarely reaches its optimal operating temperature.
This leads to incomplete combustion and an increase in soot. This heavy, sticky carbon buildup clogs the EGR valve, causing it to get stuck open or closed.
When stuck open, it continuously feeds exhaust gas into the engine, leading to rough idling and poor performance. When stuck closed, it can cause engine management lights and failed emissions tests.
Our EGR delete service is the permanent fix for this recurring problem.
Common Faults
What goes wrong with EGR systems
The EGR faults we see most often on cars and vans in Horsham and surrounding postcodes.
EGR warning light
The most common sign of a problem is an engine management light or a specific EGR warning light on your dashboard. This means the vehicle's ECU has detected a fault in the system.
The fault could be an incorrect gas flow rate or a valve position that does not match what the ECU expects.
EGR valve stuck open
If the EGR valve is stuck open, exhaust gases will constantly flow into the intake manifold. This starves the engine of oxygen, leading to incomplete combustion.
Symptoms include a significant loss of power, black smoke from the exhaust, rough idling, and poor fuel efficiency.
EGR valve stuck closed
When the valve sticks in the closed position, it stops the recirculation of exhaust gases entirely. While this might not cause immediate performance loss, it leads to higher combustion temperatures.
This can increase NOx emissions and may cause the engine to run hotter than designed.
Carbon buildup and blockage
Soot and carbon from diesel exhaust are the primary enemies of the EGR system. This sticky buildup can clog the EGR valve, the EGR cooler, and the intake manifold itself.
A blockage restricts airflow, reduces boost pressure, and will severely impact engine performance.
EGR cooler leak
The EGR cooler can fail internally, causing coolant to leak into the exhaust system or exhaust gas to leak into the cooling system. Symptoms include unexplained coolant loss, white smoke from the exhaust, and potential engine overheating.
This should be addressed immediately to prevent serious engine damage.
Loss of power or limp mode
When the ECU detects a serious EGR fault, it may put the vehicle into 'limp mode'. This is a protective measure that drastically reduces engine power to prevent further damage.
It limits engine speed and acceleration, making the car very difficult to drive.
Rough idle or hesitation
An inconsistent EGR valve operation can disrupt the air and fuel mixture, especially at low engine speeds. This often results in a rough or unstable idle, engine hesitation when you accelerate, and a general feeling that the car is not running smoothly.
Poor fuel economy
A faulty EGR system, particularly one that is stuck open, leads to inefficient engine combustion. Your engine has to work harder and burn more fuel to produce the required power.
This results in a noticeable decrease in miles per gallon, costing you money at the pump.

Same Visit
We also handle AdBlue and EGR on the same visit
While we're performing an EGR delete on your vehicle, it's the perfect opportunity to address other common diesel emission system issues. Many vehicles that suffer from EGR faults also have problems with their Diesel Particulate Filter (DPF).
We can perform a DPF delete at the same time. Similarly, if your vehicle uses AdBlue, we offer an AdBlue delete service to permanently resolve system faults.
We remove DPF, blank EGR, and delete AdBlue, often in a single visit, providing a comprehensive solution for your diesel engine.

Ford Transit Custom 2018
Mark, Horsham
Ford Transit Custom 2018
Mark, Horsham
Mark, a builder from Horsham, was having persistent issues with his Transit van going into limp mode. The warning light pointed to an EGR valve fault.
We went to his yard, confirmed the diagnosis, and performed a full EGR delete. We had the van back to full power within a couple of hours, with no more risk of carbon buildup causing the same issue.
Mark was impressed that we could get the job done at his workplace, saving him a trip to a garage.

Your Questions
EGR questions, answered plainly
The most common things customers ask us before we visit.
Does an EGR delete cause engine damage?
No, done correctly. The software file removes the EGR strategy cleanly so the ECU does not trigger warnings. A poorly written generic file is where problems start, which is why we use our own validated files per engine code.
Can I combine an EGR delete with DPF or AdBlue work?
Yes, and we recommend it on higher-mileage vehicles. One visit covers all three problem areas with one software file, one diagnostic pass, one booking. Saves time and cost compared to separate visits.
What is an EGR blanking plate?
A metal plate fitted in place of the EGR valve gasket that stops exhaust gas from recirculating through the intake. Paired with a software delete in the ECU, it prevents warning lights and stops the carbon buildup cycle for good.
Do you cover van fleets?
Yes. Fixed pricing available for multiple vehicles on the same site. Sprinter, Transit, Crafter, Ducato, Vivaro, Trafic and more, we handle them weekly.
Do you clean EGR valves?
No. In our experience chemical cleans are short-lived on a valve that has already failed. We go direct to a proper diagnostic, then either replace the component or fit a blanking plate with a software delete for a permanent fix.
How much does an EGR service cost?
Depends on the job. A diagnostic-only visit is a fixed fee. A full EGR blank and software delete is a fixed price per vehicle family. Replacement parts are extra where needed. We quote before any work starts.
