BMW E90 smoking

[Yush]

Hi guys,i dunno if im in the correct place but anyways im seeking some advice..I have a 2008 BMW 320i E90 with 87 000km on the clock...Ive noticed my vehicle smokes only when i take off from a dead stop..The smoke color is blueish white and recently after a long drive the oil light came on,when i checked the oil via the computer it says oil is full..I also have heard a bit of a pinging noise when vehicle is hot..Example like a pinging sound when a golf timing is not set correctly[/b]...Usually only at very low revs,other than that it runs well..What could be the issue here??

Check the dip stick ? Your oil sensor could be faulty?

Well like i said I'm not a mechanic. I've never checked the oil on my E90 never have. Just service it every 10k kms. My e46 has though. My bad :sorry:

My car is smoking aswell but its white smoke only smokes when im coming to a standstill and smells like oil!! So guess not the same problem. Hope you get yours sorted soon. Not a mech so not a clue whats wrong haha

Had a similar issue on our E60. I miss manual dipsticks, computers lie - sometimes.

Lol okay cool,yours could be the valve stem seal on the head...That usually causes smoking when tapping off the accelerator or coming to a stop..Hope that helps..

So just an update on my 320i smoke issue..I took it to bmw and they figured i have been using the wrong fuel,apparently i must use 95 instead of 93..So i guess all is good..:=):

:fencelook: i don't know if that will resolve your issue changing from 93 to 95

Doesn't the ECU automatically adjust to a change in fuel quality by retarding the timing? That shouldn't be your smoking issue.

 

[Dippies]

I think it does :fencelook: i stand to be corrected

 

[moranor@axis]

with what you describe im going to guess its a crack case vent issue sending oil into the intake effectively lowering the octane of the fuel as well as causing smoke...

only thing i can think of that fits both symptoms...

We have no choice but to use low-grade quality fuel in Malawi. Our cars don't smoke at all, just have to replace pumps/filters more frequently.

E90s seem to be having a weakness of ending up with a smoking problem, am on the 2006 320i M Sport Auto. smoking and I am these days checking them out on the road, I come across quite a lot of them smoking when changing gears or after an idle when kicking. the smoke smells funny as well. A friend told me I need to have re-engineering done, dont know a heck bout car repairs:flyfun:.......does anyone know if this will have the smoke stopped. I didnt xpect this 4rom BMW, can this be fixed???
