BMW M135i N55 Engine (2014) - Misfire Cylinders 1, 2 & 3 Fault Codes 140010, 140001, 140101, 140004 

dynamic duo great job men

When the fuel is getting sucked into the inlet port....the other cylinders would be getting a proportion of the overfuel.if the misfire gets better further away from the issue....it's like an imbalanced set of carburettors or float stuck open...but similar symptoms. Great job lads!!

love the video sandy keep up the great work

That was a very good and comprehensive repair Sandy. The catalyst system might come right on it does a few miles 🤞🤞 Well done lads 💪💪

nice video. I would also change the OFHG. That oil filter housing looks horrendous though. It"ll eat a belt soon if not adressed.

Hope all is well Sandy.

Good diagnosis

Thanks to you both. Another very Interesting video. Would I be right, thinking that the same fault & fix would apply to similar petrol vehicles. Not just BMW. Cheers see you in the next one. 🥃🥃

Hi, does it lose compression when having all that fuel in the cylinder ? Thanks

Sandy I have a 4 cylinder with the same symptom. Mega white smoke ,mines has a faulty injector.

Doing that test with the injector in the car is the worst thing u could do, gas washs off oil of the cylinder and u will damage the the cylinder wall, to to do that test take the injector out direct it to a bucket or a bag so fuel wont spill every where and may cause a fire ...

great video but looks like only no 1 hosing ,in other engines the coding is only for emissions it will run no issue maufactures just generating revenue stream

Bmw shitboxes always problems

Have you got a instagram or something i contact you with by any chance just to show you a camshaft on a vw polo 1.2 could do with a word of advice please
