My car started doing this a month ago and kept getting worse and worse and now it won’t start I changed fuel pump spark plugs battery soo many other things my last hope is the ignition coil if am gonna change that hopefully that fixed the problem wish me luck
The car had a rebuilt engine, the timing chain has been replaced during this time. So the noise you hear is not from that. it is actually from misfiring. Your problem sounds like a injector problem that causes misfiring during startup?
My n43 is doing same only on hot starts i think its injectors but don't know how to diagnosis them so i will change spark plugs, coils and last thing 4 new injectors if will find new parts.
Hi. I have a 2008 1 series 1.6 n43 engine. My car starts like yours when I drive it for a while. Sometimes it starts like that, sometimes it doesn't. Everytime I start it up for the 1st time in the morning, it starts perfectly normal. After that, when the engine warms up, sometimes it starts like in your video. I replaced both the spark plugs and all 4 coil packs...the problem still exists. Usually when it start heavy, I stop quickly the engine. In the next moment when i press the Start Engine, it fires up normally. Any suggestion? Thanks.
Hi! These bmw cars with n43 are really worse than french cars in reliability. I changed my fuel pump, and coils and the problem solved. Normally in this case when the coils have been changed the problem is in the mass airflow sensor or some other temperature sensor or the knock sensor so i would clean them first hand. Also bmw doesn't recommend to change the timing chain but the tensioners fail usually in about 150 000-200 000km and cause a horrible engine oil pressure failure.
@@misuffk7604 Salutare! Masina am vandut-o anul trecut si nu, nu am rezolvat problema, am mers asa 3 ani de zile. DAR, m-am tot documentat, experimentat si am banuit care e problema:Injectoarele. Am aflat de pe forumuri ca e o problema comuna la n43 ca dupa ce opresti motorul, injectoarele stricate inca sa mai curga. Practic masina nu mai pornea ca era innecata cu benzina. Cel mai simplu mod de a afla care injector/injectoare sunt problematice este sa scoti bujiile si sa le mirosi. Daca iti miros a benzina, acolo iti e problema. Eu am shimbat anul trecut bujiile si stiu ca bujia de pe cilindrul nr.1 mirosea a benzina, restul nu. Daca mai tineam masina schimbam injectorul nr.1 si eu zic ca problema se rezolva. Pe diagnoza totul era in parametrii, consumul era normal, tragea bine etc. Incearca treaba asta, vezi ce iese. Eu zic ca problema de acolo e, injectoare care curg. Cum am zis, daca nu vindeam masina schimbam injectorul nr.1. Acum am trecut la f30 328i cu motorul de n20. Macar asta nu mai are injectoare piezo ca pe n43. Succes!
@@rotilaovidiu9325 mda, mare noroc ai avut ca ai gasit sa o dai. Eu o am la vanzare de 1 an cu 5000 si nu ma suna nimeni. Am gasit in oras un baiat cu acelasi motor si el are probleme cu un injector. A zis ca nu si mai bate capul si face swap la 2.5. M a lasat sa iau piese de pe motorul lui sa probez sa vad daca rezolv ceva. Pana acum am incercat DME, senzori axe came si senzor vilbrochen. Maine ar trebui sa schimb si injectoarele cu ale lui. Sper sa rezolv. Pana acum nu am avut si alte probleme, dar de cand am schimbat astea parca a inceput sa mearga in 3 la turatii joase.
Why you post this video without any idea of what you’re talking about? This is not a bad coil pack, if it is it’s def accompanied but multiple out other codes and failed parts.
I recommend this video, now I knew it!!! My 98 F150 has same exact problem so yes! Can't wait to fix my truck this weekend
Was it coils?
Also try replacing the crank position sensor and check misfire values in INPA
Can it be the valve cover cover
Mine dose the same but stayed on high rpms
My car started doing this a month ago and kept getting worse and worse and now it won’t start I changed fuel pump spark plugs battery soo many other things my last hope is the ignition coil if am gonna change that hopefully that fixed the problem wish me luck
so ?
My car is doing the beginning noise over and over again while running, changed coil packs no change, sounds same
Check fuses if that doesn’t work check your fuel pump

@@MrMulqvist I have 3 cylinders misfiring.. still stumped on what it is
Did you ever figure out what the problem was cause I’m in the same boat?

Try to change crank case position sensor due to hot starts
I have 4 for stupid cheap got two pairs lmk

Sure it's not a fuel pump?
The car had a problem with original bosch coils. The fuel pump had been changed before.
100% injektor dead
injectors were fine, problem solved after replacing coils for spark plugs.
@@MrMulqvist yhup I replaced the original spark plugs they came with and it runs smooth no issues
Don't give out answers again
all 4?
