Following NOx catalytic converter error messages:

30E9 nitric oxide catalytic converter, aging

30EA nitric oxide catalytic converter, sulphurized*

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

 

Following diagnostics live data:

NOx concentration is 0 ppm**

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

  • 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: sensor is damaged


  • 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

 

 

 

  • 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

NOXEM series NOx emulator is built using highest quality components

  • Bosch latest generation sensor controlled and measured by ourselves developed analogue control module provides 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 guarantee highest resistance to cars on-board voltage spikes
  • High precision reference frequency oscillator and industrial temperature grade components provide uninterruptible operation in wide temperature range
  • High power oversized sensor control stage reduce heating and facilitate operation of electronics module at high temperatures
  • Double sealed construction with 5mm stainless steal base plate is guaranty of 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


Attention! 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 manufacturer. The user of the product assumes full responsibility for compliance with emission standards, valid in country of use.

NOXEM restores normal performance of NOx system, which is one of the main conditions for correct engine performance. Affirmation for successful performance of NOXEM – no new error messages regarding NOx sensor in the memory of MSD80. 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 exact description of your problem: screenshots of INPA error message list, live data etc.
