NOx Sensor Repair – Maltby, Rotherham

NOx sensors monitor the nitrogen oxide levels in your vehicle’s exhaust system, playing a key role in emissions control and engine management. When one fails, the effects range from a warning light and reduced fuel economy to a failed MOT emissions test, and on some vehicles, the engine entering limp mode.

It’s a fault that’s become increasingly common, particularly on diesel vehicles, and one that’s often misdiagnosed. At CSR Service Station, we use dealer-standard diagnostic systems to identify NOx sensor faults accurately before any parts are ordered or replaced.

Signs of a failing NOx sensor:

• AdBlue warning light or emissions system warning
• Engine management light on the dashboard
• Poor fuel economy or increased AdBlue consumption
• Failed MOT on emissions
• The vehicle entering limp mode or reduced performance mode
• Rough running or hesitation

Accurate diagnosis matters here

NOx sensor faults are frequently confused with other emissions system issues, including EGR valve faults, DPF problems, and SCR system failures. Replacing a sensor that isn’t the root cause is an expensive mistake. We diagnose the system fully before recommending any repair, and we’ll explain clearly what we’ve found and why the work is needed.

As a Bosch Service centre and IMI-accredited garage, CSR Service Station combines recognised industry standards with genuine expertise, giving you the reassurance of quality workmanship backed by trusted affiliations.
