VW Audi Group NOx Sensor Repair – Cardiff

NOx Sensor Repairs in Cardiff – Expert Diagnostics at Dominion Garage

At Dominion Garage, we specialise in NOx sensor diagnostics and repairs for diesel and petrol VW Audi Group vehicles across Cardiff. The NOx sensor (Nitrogen Oxide sensor) plays a crucial role in reducing vehicle emissions and ensuring that your engine runs efficiently. When it fails, you may experience poor fuel economy, reduced power, and even MOT failure due to emissions issues.

What Does a NOx Sensor Do?

NOx sensors are fitted to vehicles with selective catalytic reduction (SCR) systems and are designed to monitor nitrogen oxide levels in the exhaust gases. The data is used to control emissions, especially in diesel engines. A faulty NOx sensor can lead to a check engine light, limp mode, or increased AdBlue consumption.

Common Signs of NOx Sensor Failure

• Dashboard warning lights (engine or emissions)
• Loss of engine power or limp mode
• Increased fuel or AdBlue usage
• Failed MOT emissions test
• Poor throttle response

If you’re noticing any of these symptoms, it’s time to book your car into Dominion Garage to get your NOx sensor inspected.
