E and F series. FAQ

What is the difference between NOXEM NOx emulator and OEM NOx sensor?

What are the main differences between NOXEM emulator and ‘’usual’’ emulators?

Is NOXEM safe for my car?…

F series. FAQ

Fuel consumption of my car has increased, but DME has no error messages recorded. Where could be the problem?

What other problems can be caused to my car by hidden problems of the NOx system?

Are there any ways to see the “health status” of the NOx system?…
