BMW | E81, E81 LCI, E82, E87 LCI, E88, E90, E90 LCI, E91, E91 LCI, E92, E92 LCI, E93, L93 LCI with N43 series petrol engine

Symptoms of revelant problem

  • Rough idle (cold and/or hot engine)
  • Uneven run at mid/high loads
  • Misfires and error messages about misfires
  • Error messages about cylinder’s and/or bank’s fuel trim
  • Problems with cold engine start
  • Increased fuel consumption

Special features of NOXEM 130

  • Restores normal operation of NOx system and fuel economy
  • DOES NOT require NOx catalytic converter replacement
  • Restores creation of cylinders individual and bank fuel adaptations for idle, mid/high loads, cold engine – smooth operation at all conditions
  • Restores Stratified charge and Homogeneous lean fuel injection modes, regeneration, and desulfation of NOx catalytic converter
  • Increased lifetime: average more than 300’000 km

30EA nitric oxide catalytic converter, sulphurized*

*if an error appears repeatedly and/or forced desulfurization is not possible/successful

Following live data

NOx concentration is 0 ppm**

(INPA data | NOx Sensor / Exhaust temperature menu) after:

  • the engine is warmed up
  • exhaust temperature is more than 220 oC
  • driving speed exceeds 20 km/h for more than 2 min

**continuously or periodically: the sensor is damaged

NOXEM series NOx emulator is built using the highest quality components

  • Bosch’s latest-generation sensor is controlled and measured by ourselves developed analog control module which provides the highest accuracy of exhaust Lambda value. Now you can use NOx emulator Lambda data as reference
  • Up to 30V overvoltage and wrong supply polarity protection guarantees the highest resistance to car’s onboard voltage spikes
  • High precision reference frequency oscillator and industrial temperature grade components provide uninterruptible operation in a wide temperature range
  • High power oversized sensor control stage reduce heating and facilitate the operation of the electronics module at high temperatures
  • Double sealed construction with 5mm stainless steel base plate is a guaranty for long and safe operation in hard environment conditions

Electrical characteristics

  • Power supply: +9.0 .. +16.0V DC
  • Long-term over-voltage (1 hour): +24.0V DC
  • Short-term over-voltage (1 second): +30.0V DC
  • Wrong polarity short-term over-voltage (1 second): -30.0V DC
  • Maximal current consumption (+14.0V DC; +25oC): 2.5A
  • Average current consumption (+14.0V DC; +25oC): 0.8A
  • Operation temperature: -40oC .. +105oC

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.
