Disclaimer
While using NOXEM 129 or NOXEM 130 NOx sensor emulator, the NOx level, emitted by the engine in some modes can differ from value, specified by the manufacturer. The user of the product assumes full responsibility for compliance with emission standards, valid in the country of use.
Attention!
NOXEM restores the normal performance of the NOx system, which is one of the main conditions for correct engine performance. Affirmation for the successful performance of NOXEM – no new error messages regarding NOx sensor in the memory of MSD80/MSD81. However, NOXEM does not guarantee the excellent performance of the engine, if the engine has others, not related to NOx system, defects and/or the required coding procedures, as described here and here, after installing NOXEM are not performed correctly/not performed at all. If you have doubts, that your choice to buy NOXEM, is correct, please, get in touch with Bimmerprofs via e-mail and include an exact description of your problem: screenshots of the INPA error message list, live data, etc.
Bimmerprofs offers help with online diagnostics for customers. More information here.
Attention!
Do not use aerosol type spray (brake cleaner, WD40 and similar) during replacement of the sensor! The fume of these sprays can damage the sensor! Remove the protective cap from the sensor directly before installation. If a spray is previously used, dry the surface using compressed air for several minutes.

Symtoms of relevant problem
The engine cannot be started
The engine works on 2 (N43) or 3 (N53) cylinders:
- no fuel for the damaged bank (cylinders 1;2;3 or 4;5;6: N53; 1;4 or 2;3: N43);
- no ignition for the damaged bank.
Error 30BA or 30BB cannot be cleared (re-appear)
Permanent misfires (after replacement of spark plug; ignition coil; injector)
Repair description
All (4/6 pcs) ignition coil drivers (transistors) and/or low-side injectors drivers are replaced with an improved models.
New drivers are characterized by:
- higher maximal allowed voltage (480 .. 600V instead of 250V)
- higher maximal allowed current (18.0 .. 50.0A instead of 8.9A)
- lower losses: lower voltage drop at ON state
- increased robustness: 300W power dissipation and overvoltage protection
F series. Diagnostics of NOx sensor
NOx sensors could be (and very often are) the reason, why the engines of the N53B30 engine family do not use a Stratified charge. Very often the error messages regarding these sensors are not recorded in the error message memory of DME even in cases of fundamental damage. Unfortunately, the diagnostics of the NOx sensors for F series vehicles (N53B30 petrol engine family) with the diagnostics equipment is very difficult. BMW has denied access to any pe of data, which corresponds to the NOx sensor.
These sensors have several hidden defects (detailed information read here), regarding which the error messages in the DME error message memory are not recorded, but the performance of the engine is impaired, Stratified charge – turned off. Some of them:
- problems with finishing the self-test/calibration. The sensor does not switch in Online mode and does not send live data;
- incorrect offset of NOx data. The sensor sends an increased amount of NOx and misleads DME regarding contamination and damage of the NOx converter;
- incorrect measurements of the exhaust temperature. The sensor misleads DME regarding the lowered temperature of the exhaust, DME does not switch the sensor in Online mode and does not use a Stratified charge.
Bimmerprofs offers diagnostics of the NOx sensors for the F series. During diagnostics, more than 17 parameters of the NOx sensor – static and live values, are inspected.
After diagnostics, you will receive the report regarding the performance of the NOx sensor.
Disclaimer. Very often the defects of the NOx sensor are sporadic. Performing a sensor performance check, the sensor will be tested for 15 minutes, turning it on and off for at least 5 times – it will be subjected to the thermal stress to make the detection of the defects easier. If the sensor will not indicate the required performance for even one time, these problems will be noted in the Diagnostics protocol. Unfortunately, even such a scrupulous diagnostics does not exclude rare cases, when the sensor is not able to switch in the Online mode or indicates other defects. Therefore, if the test result in the diagnostics protocol is marked as “suspicious”, we recommend replacing the sensor.
We will send the report as soon as possible with comments regarding incorrect or suspicious values, the report will be supplemented with images with marked incorrect values. We will give also suggestions and recommendations for required tests if the defect could not be recognized from the data sent.
We will help your car run smoothly again.
