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.
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.

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.
