NOx sensor faults in Leicester? Avoid expensive sensor replacements with our professional mobile diagnostic and ECU solutions.
NOx sensors are critical components in your vehicle's emissions system — they feed data to the ECU that controls DPF regeneration, AdBlue injection, and emissions management. When they fail or give incorrect readings, the knock-on effects can include warning lights, limp mode, excessive AdBlue consumption, and MOT failures. It's a common headache for diesel owners across Leicester.
The problem is that NOx sensors are expensive to replace — £300–£600 each, and many vehicles have two. Before committing to a replacement, it's worth having a professional diagnosis. Many NOx-related faults are actually software issues or calibration errors that can be resolved through the ECU, saving you hundreds.
Our mobile technician serves Leicester and the wider East Midlands, bringing professional diagnostic equipment to your home or workplace. We'll confirm whether the sensor has genuinely failed or whether a software solution will fix the problem.
