Valeo Service UK is helping the aftermarket meet the growing demands of modern emission systems with the launch of its new Nitrogen Oxide (NOx) sensor range, introducing 71 new references designed to deliver accurate measurement and long-term durability across European vehicle applications.
The latest expansion strengthens Valeo’s emission control offering, providing coverage for more than 40 million passenger cars. By matching European fleet composition across a wide range of makes and models, the new range helps reduce catalogue gaps and gives workshops and distributors greater confidence when sourcing replacement components for complex exhaust systems.
As emissions legislation continues to evolve, accurate monitoring of exhaust gases has become increasingly important. NOx sensors play a critical role within Selective Catalytic Reduction (SCR) systems, measuring nitrogen oxide levels and helping ensure the system can convert harmful emissions into harmless nitrogen and water.
“Modern emission systems are becoming increasingly sophisticated, creating new challenges for independent garages that need reliable replacement parts and accurate technical information,” said Andy Swann, Managing Director at Valeo Service UK. “Our expanded NOx sensor range provides workshops and distributors with quality parts supported by the technical expertise and aftermarket support they need to achieve first-time-right repairs.”
The new references complement Valeo’s existing sensor portfolio, which now includes more than 2,000 sensors, reinforcing the company’s position as a complete partner for automotive professionals across a broad range of applications.
Designed to withstand the demanding conditions found within modern exhaust systems, Valeo’s NOx sensors are engineered to provide consistent performance in real-world workshop applications. Each sensor is developed to resist severe engine vibrations and extreme exhaust temperatures, while supporting Euro 6 vehicle requirements where sensors positioned before and after the SCR catalyst monitor system efficiency.
To ensure reliability beyond laboratory conditions, Valeo’s NOx sensors undergo 700 hours of road testing across real driving situations and varying duty cycles. This validation process helps deliver the durability and performance required for vehicles operating in everyday conditions.
The Valeo UK Technical Hotline provides direct access to specialist support for fitment queries and application requirements, while Valeo Tech@ssist offers free online access to more than 45,000 references, technical documentation, assembly instructions and weekly training webinars.
Workshops can also benefit from the Valeo Specialist Club, a fully digital rewards programme that allows technicians to scan product barcodes using their smartphones and redeem points against a wide range of rewards.
