EGR & DPF Cleaning Services

We provide thorough cleaning and fault resolution for EGR valves and DPF systems. These components often clog or fail over time, causing power loss, warning lights, and failed emissions tests. We assess your vehicle, identify the fault, and apply safe, practical solutions to restore performance. Our approach saves you from costly replacements and keeps your car compliant. Whether it's a diesel or petrol model, we help your engine breathe easier and perform better without unnecessary delays.

AdBlue System Solutions

We diagnose and resolve issues related to AdBlue systems, which are often the cause of dashboard warnings or restricted engine performance. Our services include fault detection, repairs, and AdBlue delete options for off-road or specialist vehicles. If your system isn't working, we'll find the best route forward—legally and safely. We understand how AdBlue integrates with your car's emission controls and provides clear, reliable fixes to restore everything.

Swirl Flap & Lambda Sensor Removal

Swirl flaps and oxygen sensors can lead to engine faults or performance drops when they fail. We offer removal or replacement services depending on your car's needs. Removing faulty swirl flaps helps improve airflow and reduce fault risks. Likewise, eliminating lambda sensors in non-critical areas can boost stability and power. We carry out each job carefully, ensuring the changes are safe and tested. Every fix is based on experience and backed by solid diagnostic checks.

Say Goodbye To Fault Codes

We clear persistent engine fault codes that often return after changing parts. These codes can cause dashboard lights to remain on or affect vehicle performance. Our service identifies the root cause and either repairs or deletes the affected data safely. This includes DPF, EGR, AdBlue, and sensor-related faults. We don't just mask the issue—we get to the source and solve it correctly. Let us help restore peace of mind and driving comfort.
