F10 n53b30 missfire
Discussion
Dear members!
3 injectors and 6 ignition coils+ spark plugs have been replaced in my car already but misfiring and cold start shaking still presents.
Only missfire error code showing in ecu.
Do I have to change the other 3injentors? First 3 is now index11 the other 3 is index08. (Use only premium fuel, 82k miles)
Any idea?

Where did you take it to have only half the job completed? Sounds like the other 3 injectors need to be replaced.
Sounds odd why 3 would be replaced only, unless they are all in the same bank which *should* resolve the issue unless the fault was in the other bank, or all of your index 08 were shot.
What car and year?

F10 528i 6cylinder.Sounds odd why 3 would be replaced only, unless they are all in the same bank which *should* resolve the issue unless the fault was in the other bank, or all of your index 08 were shot.

My mechanic diagnosed those in the first bank to be replaced. First three inejctors leaked.
Also measured compression in the cylinders and the other 3 in the second bank looking ok.
So I dont know what to do. Change the other bank? Or something else could be wrong.

or take it back to the garage and get them to fix it
but yes index 11 x6 is the "fix" usually
what year? interesting an f10 has index 08, presumably yours is 2010/11.
Mines a 530i and it had new index 11 four years ago and touch wood all good.

I’m not happy to change all the six but I’ll do if necessary.
I'm not sure I should do that yet, considering they have no problem. That is why I am questioning here.

yeah fair enough. if you are sure there is no prob with those injectors maybe start looking at the mosfets in the ecu then. Try bimmerprofs for info.I’m not happy to change all the six but I’ll do if necessary.
