One of the most common faults linked to AdBlue systems is failure of the NOx sensor. These sensors measure nitrogen oxide levels and are crucial to the operation of the AdBlue system. When they fail, the result is often dashboard warning lights, reduced performance, or the dreaded countdown to no-start.
At STX Tuning in Slough, we offer a NOx sensor delete service alongside our AdBlue delete solutions, with both workshop and mobile coverage across England.
Common NOx Sensor Problems
NOx sensors are a frequent failure point on many popular cars and vans, including:
-
Mercedes C-Class, E-Class, and Sprinter – regular NOx fault codes leading to limp mode
-
BMW models – dashboard warnings caused by faulty NOx sensors
-
Audi A4 and Q5 – combined AdBlue and NOx issues causing no-start situations
-
Ford Transit and Ranger – recurring NOx sensor failures linked to AdBlue errors
-
Peugeot and Citroën vans – injector and sensor problems causing repeated warnings
Replacement NOx sensors can be expensive, and in many cases, customers find the same fault comes back again.
The Benefits of NOx Sensor Delete
Our NOx sensor delete disables the faulty sensor electronically through ECU programming, ensuring the issue does not return.
When combined with AdBlue delete, you benefit from:
-
Permanent guaranteed fix for both NOx and AdBlue faults

No more limp mode, warning lights, or countdown timers

Avoidance of high dealer repair costs for replacement sensors
