- I removed NGK iridium spark plugs and have replaced them by new Denso with smallest electrode in the world.
I also removed all injectors and cleaned them by ultrasonic cleaning machine with testing as well. They were clogged.
Then I have replaced all o-rings by genuine new.
One problem is permanently solved !!! Its twitching during driving when the engine is cold.
After cleaning the injectors you had no issues so far? I heared that after cleaning new type bosch injectors they might start leaking after some time..
Mne to tiež robilo po naštartovani , take zahavanie s otáčkami. Dal som nové solenoidy, vyčistil vanos filtre. Raz mi vyhodilo misfire na 3 valci , tak som dal novú cievku + všetky nové sviečky . Odvtedy mi to nerobí. Klop-klop :)
Já tam mám také nové cívky, svíčky i solenoidy, filtry čisté, vstřiky čisté a ty studené starty jsou prostě nějaké divné. Ten studený start je takový hrubý a někdy tomu třeba 10s po nastartování samy od sebe vyběhnou otáčky na 1500rpm. Nebo to lehce zakolísá. Když bych to klidně po minutě nastartoval znovu tak už to nastartuje normálně. Když je motor studený a čím větší je zima tak to startuje lépe. Když je venku horko a motor je studený tak ty starty jsou nejhorší. Jako by na to měla vliv teplota nasávaného vzduchu nebo nevím co by to ještě mohlo být.
Hola! Saludos desde Chile, me gustaría saber si tienes video de cómo sonaba el vehículo antes de solucionar el problema
@Slafiml
No vanos solenoid need cleaning and return check valve if the problem continues will be vacuum problem
Hola! Lo pudiste solucionar?
How is the power and consumption with the denso
My car has vibration on hot start, and RPM shoot to 1000 and the oscillate between 1200 and 1000 before settling. So weird.
Do you recommend double platinum or iridium plugs? Bosch or Delphi coils ?
Good video thanks!
Hi, are you able to post the video with your hot start? It is hard to say why it happening. I need to see your needl during fluctuation and also hear the engine sound. However, did you tryed to clean your vanos solenoids, vanos filters ? I recommend only spark plugs with genuine code, means for this car with one electrode. I think it doesnt matter if you buy new NGK or Denso, but according realoem.com and your vin number you can find last specification released by BMW. Acc. this you can verify if its platinum or iridium. About coils I have bought genuine new frow BOSCH but next time I will choose from DELPHI with stainless steel protection, they are better.
@blue part of the hose where u release mine seems to be different mine looks to have a bolt I have to unscrew have u ever seen that I got same enegine to
Did the injectors cleaning solve the bouncing idle on cold start?
Unfortunately not, there is still somethink wrong and I dont know what but it is only cold starts, during driving it runs smoothly 😀
