NOx Sensor Repair - Dagenham & South Ockendon

Modern diesel and petrol engines are fitted with NOx (nitrogen oxide) sensors, which monitor emissions and help your car stay efficient and environmentally friendly.

If a NOx sensor develops a fault, you might notice:

• the engine management light come on
• reduced performance
• higher fuel consumption
• or even difficulty passing an MOT emissions test

At A1 Autocentre, with branches in Dagenham and Ockendon, we provide expert NOx sensor diagnostics and repairs for all makes and models. Using main dealer-level equipment, our technicians can accurately identify faults with the sensor or surrounding systems and replace parts only when necessary, saving you time and money compared to guesswork repairs.

Our team of eight experienced mechanics, including Level 4 EV specialists, work on everything from family cars to vans and hybrids. As a family-run garage and proud Top Garage finalist three times, we’re trusted by drivers across the area for honest advice and reliable service.

Both our branches are designed with your comfort in mind. You’ll find welcoming reception areas and waiting rooms, customer toilets, good parking, and excellent transport links, with nearby train stations offering direct services into London – making it easy to drop your car off while you carry on with your day.

A1 Autocentre is proud to be part of the Castrol Service network of quality independent workshops. We are also pleased to be affiliated with other respected motoring associations such as the Hybrid and Electric Vehicle Repair Alliance (HEVRA) and the DPF Doctor.
