Mercedes Benz Petrol & Diesel Vehicles with NOX Sensors

Mercedes Benz petrol & diesel vehicles with NOX sensors can cause engine management lights (EML) to come on, or AdBlue &/or AdBlue countdown until a non-start
situation occurs. 

The sensors are prone to failure & have been superseded to newer design to rectify the fault. The Engine Control Unit (ECU) will also require software calibration number coding (SCN coding) using the Mercedes STAR / Xentry diagnostics machine of which MotorAid have their own genuine Mercedes Benz diagnostics
machines with direct factory link to Mercedes Benz in Milton Keynes for all coding issues to be rectified. 

There is an ongoing issue of supply of NOX sensors, the situation is starting to abate however, and we are finding genuine NOX sensors being dispatched outside the dealer network now. O.E sensors are also once again available.
