NOx Sensor Repair – Ashford, Surrey

At Boxer Motor Works, we offer a NOx sensor repair service at our workshop in Ashford, Surrey.

In modern vehicles, the NOx sensor passes information to the ECU (your vehicle’s brain) about levels of NOx and carbon dioxide within the system. The ECU utilises this information to keep the engine running efficiently, to keep fuel economy at an optimum, and to help minimise toxic exhaust emissions.

If the NOx sensor fails, it’s pretty easy for experienced motor technicians to pinpoint that as the cause of the symptoms that you may have noticed and to repair the faulty sensor.

Signs of a faulty NOx sensor are:

• A noticeable increase in fuel consumption
• The car goes into limp mode
• The check engine light coming on in the dash

These can also be symptoms of other mechanical issues, so the best advice is to get in touch with our team at Boxer Motor Works and we’ll be happy to help and advise.

We are proud to hold accreditations from leading industry bodies, including IGS, Bosch, RMI, Mobil, and ASNU — demonstrating our commitment to high-quality service, technical excellence, and trusted standards across all aspects of vehicle diagnostics, servicing, and repairs.
