After lambda replacement make sure to replace all of the spark plugs. They may be damaged or dirty.

I don't understand your remark around the @07:42 mark. Stratified charge after raising engine RPM in idle is the correct response isn't it? So what is wrong here? Is it possible to check stratified charge functionality of the engine in Idle?

Thanks always best videos for N43! So the real issue was the valve cover? I sometimes have a misfire when drive at 50 km/h with low rpm and steady low gas. Did you change the lambda on hot exhaust?

Thanks! This problem leads to Nox system, stay tuned! The exhaust was almost cold when I replaced the Lambda sensors.

@@JaniVoutilainen So the valve cover stll didnt fixed it ? Can you maybe show how the old breather valve looks like and if its possible to open and close it ? I found an repair membran but but bot 100% shure if its possible to close the cap after opening..

Hello! Do you remember after replacing lambda probes if stratified charged turned on when acc. pedal was pressed or it was related to NOX problem Thanks 7:40

I think that's just normal and it is not problem. For example, at idle, when the throttle is given for a moment, the engine enters to stratified mode.

Thanks for the upload!!! Is the post-cat sensor the NOX sensor?

Hi! It is not. These are lambda sensors for CO cats. 2 for before cat and 1 after cat. Nox sensor is behind Nox catalytic converter. Nox sensor and converter locations is about middle of exhaust system... My problem will lead to Nox system... Stay tuned! 👍

Great when the video is helpful! I'm just an ordinary guy who learns N43 engine life of the soul! 😉

I have changed NOX sensor, ignition coils, spark plugs but I still get the 30EA code, what else could it be? 30C1 too Car feels amazing, only at low revs (below 1k rpm) hesitates if I dont apply throttle and yellow check engine light comes up on the display after a couple of minutes (not on the dash), if I restart the car it disappears.

30EA nitric oxide catalytic converter, sulphurized Read this: bimmerprofs.com/30ea-nitric-oxide-catalytic-converter-sulphurized/ and watch my youtube video: kzread.info/dash/bejne/pn6t1sN7gruopto.html Especially after Nox sensor replacement, did you: 1. encoded new Nox sensor to the car with Ista-D 2. All error messages - erased 3. Desulphation session of the NOx converter completed 4. engine - re-adapted If you have not performed those steps after replacing the NOx sensor; I recommend to do it as quickly as possible before the NOx converter is damaged. Hope you can solve the problem!

Are the two pre and post sensors the same? Or do I have to get the exact sensors for pre and post?

Those three sensors are with different lenghts and they have different part numbers. Stay with originals 👍

Hi, nice videos👍. I have a diesel 330xd touring 2006 and the engine light on😒, and a leak of power about 1000rpm to 2000rpm😒. About 2 weeks I take the car to bmw diagnose the problem, the problem was dpf stuck😔. The mechanic in bmw said to took the car to clean the dpf in a guy that they recommended to clean dpf stuck. The guy that clean the dpf said that in the diagnostic also give the air mass metter. He said if the engine light comes again😳 to go and make a diagnose but probably were because of air mass metter. Well the problem know it's ccid-31 emission gazes. I have changed the air mass metter and the error code is still there.😒 Some one with same problem, and some one can tell what is the cause? I think its the o2 sensor🤔

Loistavia BMW korjausvideoita! Saitko tuon vikakoodin 2C32 pois? Korjaantuuko suuttimien vaihdolla? Itellä samaa vikakoodia heittelee silloin tällöin ja tyhjäkäynti täristää kylmänä.

Hello Yani, at 5:22 minutes when you press F1, it appears "Error ecu conditions not correct or request sequence error". What is the reason? How to fix it? Danke

Possibly a silly comment , but is the NOX sensor different to lambda sensors , and if so where is the NOX sensor located?

I'll copy paste Jani's answer to the same questions... Yes it's different. The sensors in the video are lambda sensors for CO cats. 2 for before cat and 1 after cat. Nox sensor is behind Nox catalytic converter. Nox sensor and converter locations is about middle of exhaust system... Here's a link to a diagram of the N43 exhaust system where you will see all the sensors etc bmwfans.info/parts-catalog/E90/Europe/318i-N43/browse/exhaust_system/lambda_probe_fixings/

What tool did you use for oxygen sensor? Im gonna DIY this 😁

What are the length of 2 pre-cat sensors: 11787569930 and 11787539123? I think one is short other is long.

The 1st sensor is 21,65’’, the 2nd is 28,34’’, the 3rd is 18,89’’

This is BUG in MSD80 software. N43 have only 2 wide bands and 1x narow band, second narrow band is mirrored from 1st. You have error on 2nd narrow band. This happens cuz software jumps into N53 code area - BMW BUG. You have defective NOX sensor or emulator.

I have three error codes...the number of the codes are 2C2D, 2C3D, 2C7F ...i have had change the lamda sensor at Bank 1 pre cat side with new one ànd still have those error codes again...what to do next
