If you drive BMW with petrol N43/N53 series engine and the engine
pay attention to error messages stored in the engine control unit. If the error messages regarding NOx system
replace the OEM NOx sensor with NOXEM series NOx emulator!
The original NOx sensor costs at least EUR 550, NOx catalytic converter – EUR 5000 .. 7000, a lifetime of both items typically do not exceed 100’000 km.
The cost of NOXEM NOx emulator is lower than the cost of NOx sensor, the average lifetime of it – at least 300’000 km, and there is no need to replace the expensive NOx catalytic converter! In addition – thanks to lower fuel consumption, NOXEM NOx emulator will fully payback after 30’000 .. 40’000 km.
The installation of NOXEM NOx emulator is quick and simple, it doesn’t require intervention in the electronics and exhaust system. You will be able to switch back to the original exhaust solution at any moment if you will decide to do that.
Here you can find detailed information about the most popular N43/N53 series engine problem and here – how to check NOx system performance (E series) (F series).
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/MSD87 (exception for MSD87: 12C401, detailed information read here). 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.

Note: Problems with NOx system (NOx sensor and/or NOx catalytic converter) usually are the reason of following errors (E series; typical situation):
Also, error messages regarding fuel trim usually appear. Problems with NOx system also can be the reason of: error messages relating (individual or all) cylinders misfires; low efficiency of CO catalytic converter, 1st/2nd Bank; Lambda probes; incorrect fuel trim (cylinders individual or Bank).
