Emissions Diagnostics & Repair Specialists

Modern vehicles rely on multiple emissions systems working in harmony: lambda sensors, catalytic converters, diesel particulate filters, EGR valves, and AdBlue/SCR systems. When any of these components fail, it can result in MOT failure, warning lights, reduced performance, and increased fuel consumption.

At EcoMax Tuning, we have the specialist diagnostic equipment and expertise to pinpoint the exact cause of emissions problems and provide targeted, cost-effective repairs.

Whether you've failed your MOT on emissions or have a persistent warning light, we can help.

Frequently Asked Questions

Yes! MOT emissions failures are one of the most common reasons customers visit us. We diagnose the root cause, whether it's a faulty lambda sensor, blocked catalytic converter, DPF issue, or EGR problem, and provide a targeted repair to get you through your MOT.

Common causes include faulty lambda/oxygen sensors, worn catalytic converters, blocked DPFs, stuck EGR valves, failing AdBlue systems, injector problems, and general engine wear. Proper diagnostics is essential to identify the specific cause.

Most emissions repairs can be completed within a day. Simple sensor replacements or ECU recalibrations take 2-4 hours. More complex work like catalytic converter replacement may take longer. We'll give you a clear timeline at diagnosis.

Costs vary depending on the specific issue. ECU-based solutions start from £199, sensor replacements from £149, and more complex repairs are quoted individually. We always diagnose first and provide a clear quote before proceeding.
