Hi all,

Car worked fine in the evening, no issues when it was parked. When I go to start it up, I hear like a whistle which my wife also heard in the house, and then it starts idling bad, and most likely running on 3 cylinders max.

Looking around me, I see this very thick foggy smoke , white smoke around...

I don't think a turbo seal blown can happen at startup, they tend to leak before little by little...
Coolant is all there, obviously it is oil...

Can the PCV valve do this ? I need to take off spark plugs today and see which cylinders are flooded with oil..
Codes are missfires on 4, 5, 6 only; nothing else....

One more thing, it is stock, as I took the JB4 out a few months ago... I never got around fixing the hesitations, they seem to be less obvious without the jb4 to the extent that the car is perfectly drive-able stock.

any ideas welcolme... one idea I have is to torn her apart and sell it for parts

Thanks a lot

Nobody ?

Sounds like it could be a bad injector/s did you pull the codes from the ecu ? Check the plugs for unburnt gas or oil it's all about trouble shooting at this point start with the easiest and go from there good luck

I pulled out the spark plugs , there is no oil anywhere, just fuel... heavy smell of fuel even after sitting one day in the garage... I believe some injectors stuck open. It complains about misfires (I mean I read the codes ) in cylinder 5, 6 and multiple misfires...
Would this be safe to assume it is injectors ? But can overly rich mixture produce white smoke, lots of it ?
The only thing I did not change on this car is injectors ( I mean I replaced one, with a second hand one... worked for 10k miles I suppose, but never pulled the trigger on a set of new injectors ) .

Would there be a chance to be a bad DME ? that is something I cannot test ...

Thanks

Usual leaky injector

If it's a 2008 with original injectors, at this point you may as well replace them all. And if you have the old msd80 Ecu hope it didn't short a transistor - I think some early 08's had the older dme

It's not your ecu it has to be injectors with out a doubt if your ecu fried you would have a whole bunch of issues just bit the bullet and buy new injectors just make sure to buy inpa software along with it to code them in

Hi all and thanks for all replies,

I bought a couple of second hand injectors before splashing out onver 1G on injectors, and it seems that it was that... engine purrs nicely now with 5 and 6 injectors changed and coded (I have INPA on a laptop).

I actually bought a set of 6 new ones, index 12, so that should fix the issues... I am hoping no more problems with this car for a while... I never had any crap with my E46 M3 ( which I miss a lot ), my E36 M3, etc... These new engines are so complicated and many parts prone to failure. I am pretty sure it is also due for a walnut blast, so that's my next step for teh summer, when weather warms up (it seems that you can rent the equipment from bavarian auto ).

Cheers
