BMW is in a world of it's own.

It seems from your computer the NOX sensor was faulty. I have a cold start rough idle issue with my 2008 E90 with N43 engine on 130k miles, and my diagnostic tool is giving me multiple NOX sensor fault codes. Will probably try swapping for a used sensor first. The sensor or its heating element eventually fail.

Hi Sandy , any update for the problem of BMW 318i N43 (E90 2010)?

ambient air pressure is to low 1000 hpa = 1 bar at sea level i would have thought it should be around 1000 hpa unless your'e on a mountain i'm just wondering where it takes this measurement from of course i could be wrong but it might be worth checking

I suggest to clean the mass air flow sensor with MAF-cleaner. Dirt on the airflow sensor is a common cause of rough idle. Don't use brake-cleaner or any other cleaner as the sensor will fail with anything else. MAF-cleaner is the only option as it doesn't leave residue, it dissolves completely.

Operation Mode shouldn`t be "Homogeneous". The primary and the most advanced Mode is "Stratified Charge" then is Homogeneous lean. Homogeneous only is kind of emergency mode

what is the pad you are using or app?

Hey Sandy, have you got a chance to confirm what the fix was on this one?

Dont we just love our job Sandy , less and less spanners and screwdrivers , more electronics every day , good job we are all cheap 😎😂😂

Am I right in thinking to stay away from this engine??

Did you get a fox for this ?

How did this go? Fixed? 😬
