- Diagnosis of NOx system; NOx sensor and NOx catalytic converter
- Lambda value drops in Bank 2 and cause DME to trim lambda sensors
- Virtual probe situation with faulty NOx sensor
- Fault code from after-cat control probe in Bank 2!
- These vehicles DO NOT have a control probe in Bank 2!
- Updating DME software will not help in this situation.
- The NOx system is located in the middle stages of the exhaust system
- Replacement and coding of NOx sensor with ISTA-D
- Maintain your own NOx system, it is very important for the operation of your car!
Does replacing the NOx sensor solve the misfire problem? Watch this video!
Additional Note for testing Nox system:
After few minutes of driving motor temperature should be 90 .. 112 oC.
If not, make sure you fix the situation; as the NOx system will not work properly if the engine temperatures are not normal!

My purpose is to encourage people to do things themselves!
Plus, this is a nice hobby for myself and at the same time I have the opportunity to save a lot of money by doing all the maintenance myself!
I’m not a professional with cars or motorcycles, I just want to learn how to do things myself.
If you do this service yourself, always check the correct instructions in the official service manuals. This is just my way of doing it!

Dear Jani, Thanks a lot for all of your movies regarding the n43 engine. I'm pretty sure they will help me out at some point. I had to exchange the injectors and the nox sensor (Noxem) and would have been glad if your videos exist at that time. Go on with your excellent work. Best, Georg

[@brianbridox6685]

Very clear video! Thanks.

[@garydeasy]

Great videos btw Jani !! Keep them coming , really helpful !

[@dancristianb9651]

Thanks Jani for another great tutorial on how to proper maintain the N43 engine! ;)

[@ezracamilo425]

I realize I'm kind of randomly asking but do anybody know a good place to stream new movies online ?

[@brantleycristian8088]

@Ezra Camilo I use FlixZone. Just google for it :)

[@emilianobishop9934]

@Ezra Camilo Try flixzone. You can find it on google :)

[@jiazirun5630]

Good job as always! Thanks for sharing:)

[@JaniVoutilainen]

Thanks! You're welcome! 😊

[@camielnijpels]

Hi Jani, Do you know why the option to replace the nox sensor is in ista but there is nothing i can do with it. The item on the right doesn't show up. Could it be a faulty ista version or could it be something else? Thanks in advance

[@Adam-id1th]

that tool is badass :)

[@szoboszlainorbert9659]

Dear Jani. I have replaced my NOX sensor and the question is when you reset the Nox sensor itself should the offset value start from Zero and stop it somewhere 3,4 after a run? How is your value? Thanks

[@nabs2714]

Nice video very informative..

[@flippingcarsrepairs]

Hi on the n43 engine do you no we're bank sensor is as mine 1.2v are inpa in the red 👍👍👍👍👍👍

[@irushzz2442]

any idea where i can download ista d? you got any link for me or can you send it to me? i checked the internet there are several links but all of them are from megadownload and that requires me to pay after 5gb or so... pls help

[@tanoliam]

Hi 👋, I watching all your videos and there are amazing, you are a professional 👏 😀, One question, I drive a 320i with the same engine N43, my problem is when idle start are bad and when engine are warm is bad too, I change coil packs , sparks, o2 sensor ... The problem in my Icarsoft when I scan obd tells the error code 30EA...catalytic converter sulfurized....I see with a cam inside the catalytic converter and all seems fine , in live data with my icarsoft scanner at the parameter of nox sensor it's figure - - -, do you have a wasap or a mail and perhaps can I send you the photos of my probes, thanks a lot, Martin

[@kevcat8655]

Anyone know what could be the cause of DME '2D2A' error code for N43 enigine? Which sensor would it be? It says 'differential pressure'?

[@Alex-zi6ym]

Does it work/ fix the issue if you only replace the part and not do the coding? I just took my 1 series E87 to a garage to be repaired and they said it didnt need coding and only needed the part replacing. I provided them with the part. Have they dont it right? Hoping someone can help

[@antares88]

Kann man den auch mit inpa codieren?

[@kristapsvikmanis4152]

After replacement with aftermarket NOX sensor i have error - 2AED DME: Nitrogen Oxide Sensor,Version. Mechanic says adaptions was made, or maybe its because sensor is bad.?

[@bigdeal87]

Woow THX! Glad to see oem part fixed your issues ! Will control my NOX sensor ASAP! What mout kit do you use for the surface ?

[@JaniVoutilainen]

Thanks! The surface has no mounting. It rests on the adjustment knobs. So far remained in place! 😉

[@user-be6mu5xy4u]

0030EA digital motoelektronik (DME) Denox catalytic converter sulphurised Hello, should I change the NOx sensor and adapt with this fault code? Can you help me? Dankeschön

[@mathice]

I did it without coding, no problems so far .. Is it really necessary?

[@nickemfive8866]

This is an excellent video series! I followed the video on the injectors, changed and coded them. Unfortunately it didn't fix all issues. It may still misfire if you're at steady speed and approaching a hill for example. Then you can really feel it. You have to stop and restart. Then then the engine light goes away and you can procede as before if you go slower. On INPA it throws cyl 4 misfire and DeNox-catalyst fault codes. Have already changed the plugs and ignition coils to OEM ones. The previous owner had the timing chain done and also did a compression test which was ok. So I don't think the engine has a mechanical problem. I am suspecting the nox sensor now since most other things are changed. Does anybody know if the procedure of changing the sensor is nearly identifical on a E61 520i with the N43-engine? I am wondering how many panels I would need to remove to access it? Is the nut a 22mm? Nice tool there. Is that one available on ebay etc? Would the nut need heating with gas before attempting to remove it?

[@JaniVoutilainen]

Thanks! Hope you can find solution for your e61. That tool is super and founded it from local store 👍 Sensors from exhaust can be very tight, but helps if you have correct tools.

[@MartiansChronicle]

Good video! I only get a 30EA error - no other error about the NOx sensor. However, the "Schubabschaltung" value is "!14.00" in the NOx-Sensor page. In your video, this value was "!10.00". The NOx is transmitting data. The "Lineares Lambdasignal" is working - sometimes the car goes into Stratified mode. Do I still need to change the sensor because of the "Schubabschaltung" value?

[@szoboszlainorbert9659]

Hello. I have replaced mine because my offset value was !12. Resetted it and its working properly. The car goes into Stratifyed mode. The only thing is that the offset value still 4 instead of Zero. I don't know should be Zero at all!?

[@MartiansChronicle]

@@szoboszlainorbert9659 I believe this value is supposed to change. I've had it at 0, 2, 3, 4... etc. If I'm not mistaken, when driving, if you lift off the throttle, the value should change. With my old sensor, I didn't see this change. With the new one, I haven't checked it live i.e. when driving but only when the car is stationary.

Hi, I have one bmw 330xd e91 2006 diesel and I have de code ccid-31 gazes emissions some one can tell me what to do I think it's the lambada.

Hello, Could i ask you, what tablet are you using? I want buy tablet for ISTA/INPA, but i can´t find nothing ideal for it.

[@JaniVoutilainen]

Microsoft Surface Pro This device has a storage capacity of 128 GB + 256 gb microSD card. That's enough for both ISTA-D and ISTA-P

[@CosminRotaru]

Inpa interface is already quite busy. When you overlay it with the video it's almost impossible to follow what's going on...

[@CorneliusHardyMedia]

Hey where did you find the part. I can't seem to find one for my 07 328i

[@JaniVoutilainen]

Car parts can be found with the car's VIN number, for example, at bmwfans.info/ There you will also find the part number with which you can search for the part, for example on Google.

Hi i have problem fault i dont What new needs sensor nox i have bmw 320i 2010 P2273 P0420 P0430 P114C PLEASE HELP THANKS

[@garydeasy]

Hello ! I have recently bought NOXEM 130 from Bimmerprofs. I am getting a mechanic to physically fit part because I cannot get under my car. He asked which lambda probe does it replace. There are 2 Oxygen sensors in exhaust on the underside of the car. Anyone know is it the pre cat or post cat sensor you replace? Help would be greatly appreciated?

[@JaniVoutilainen]

It comes after Nox Catalytic Converter. That is, in the middle of the exhaust system as you can see in this video.

[@alejandrosantiago3017]

Buenas tardes desde España. Espongo mi problema jani para saber si me puedes ayudar. Tengo un bmw e93 motor n43. El vehículo presentaba fallo de relenti inestable alto consumo y falta de potencia. 1 se remplazo bujias. 2 bobinas. 3 inyector. Solo quedaba la sonda nox y hoy se remplazo por una nueva original. Todos los códigos de error se fueron.pero el coche presenta un fallo de funcionamiento (tirones y falta de potencia) todas las adaptaciones se ha completado con éxito. Pero al desmontar bujias veo que están muy negras. Mi pregunta es seria conveniente poner nuevas otra vez solo tienen unos 4000 mil km. Gracias de antemano

[@JaniVoutilainen]

I would put in new plugs and replace the rest of the ignition coils as well as do a forced cleaning session for the NOX Catalytic converter and reset and re-teach the adaptations if you haven’t already done so. If you still give misfire, then you should check the misfire counters so you know which cylinder is causing it. I hope you find a solution! 👍

[@runebdrim6733]

Has solucionado algo?

[@Patraulea91]

I have 2af2, 2af4 and 2af6 errors, should i change NOX sensor? Thank you!

[@tobiasherrmann5817]

Me too - ISTA say yes to your question- but I will wait... this happen only if I am on highway with over 180km/h But no MIL, nothing- only if I read the errorcode via ISTA I will change my spark plug etc... (Is over 140.000km)

[@JaniVoutilainen]

It seems a bit that the NOX sensor should be replaced. Another option you can try to do is change only the probe: kzbin.info/www/bejne/naK0mGSbZsmanKM

[@coolwicia]

I understood correctly, after deleting the ista adaptation no I have to go to the road to do the adaptation as in the case of inpa?

[@streetfighter4dude]

Did you do this? I cba because it’s a long process but I’m thinking whether I should or not

[@Tweekzify]

Great guide really!!! But encoding new one possible with Ista-D only?

[@JaniVoutilainen]

Thanks! You can do encoding with INPA also 👍

[@Tweekzify]

@@JaniVoutilainen Really?? Cause INPA i have. Ive been driving with new NOX sensor for a while without encoding it. (Maybe its bad??) But i havent found encoding with INPA anywhere, do you have a guide? Kiitos

[@JaniVoutilainen]

@@Tweekzify Hi! I first read that your comment is about injectors! 😂 Sorry, as far as I know, it can only be done with ISTA-D only. Never done it with INPA... Does anyone else know?

Hello 🙋‍♂️Great Video well done💪I want to ask you what should Nox concentration before and after kat should be? My nox befor kat goes up to 400ppm while driving and Nox after kat goes up to 1000ppm? Its a x5 30d? What do you think? Greating 🤙

[@JaniVoutilainen]

Thanks! 👍 The NOX sensor measures the Nox concentration after the NOX Catalytic converter. The N43 engine does not have a sensor before the NOX Catalytic Converter. But I'm not sure about the x5 30d ...

[@JaniVoutilainen]

Hi! Those fault codes are related to CO catalytic converters and NOX sensor. More detailed research would be needed, for example with INPA or ISTA-D. You should read these websites: bimmerprofs.com/n4353-co-catalytic-converters/ bimmerprofs.com/replacing-nox-sensor-n43n53/

[@BmwOwnerAndLover]

I cant get it lose

[@lefterisapostolou6616]

Is coding needed or it can not be done?

[@JaniVoutilainen]

The BMW manual says that needs to be done. Otherwise, the new NOX sensor will not adapt.

YES STAY AWAY FROM THE DEALERSHIPS AS IT COSTED ME £2214 TO GET THE NOX SENSOR FIXED AT BIRMINGHAM DEALERSHIP UK

[@JaniVoutilainen]

Oh no !! The nox sensor is already really expensive though and the dealer is taking its own addition. And working hours in addition. But £ 2214 is a robbery !! 😳🤬🤯
