Question about BMW 320i
The car was taken for dinostic tests with no solution.
Blue smoke is caused by oil. Rich running causes black smoke and will set the check engine light. Rich running (black smoke) on startup could be caused by a leaking injector. The blue smoke puff at startup is likely valve stem seals leaking or a bad crank case vent malfunction and sucking oil into the manifold at high vacuum conditions.

Blue smoke come from burning oil. This means that you have an oil leak somewhere that it is getting burned up and exiting the muffler. First thing I would do would be to check your engine oil level. After you are sure that it is good, I would suggest taking the vehicle to a mechanic to have them see if they can find where the leak is. Let me know if you have any other questions. Thanks for rating my response and for using FixYa!

The Exhaust Emission Light can come on if the car is driven slowly over short distances.It will not happen on cars driven at speed. A short trip of ten miles at over 3000 revs should reset the warning light,although it may not go out for a couple of days after you have tried it . Hope this helps and saves a bill at the local dealer. JK

Te blue smoke is oil getting into the piston/fire chamber..
If it is only at start-up - it is more than likely the valve seals.. Allot of the time they use plastic ones so therefor it is somewhat common for cars to do this..
If it is not to bad and stops soon after start-up,, its not really a big deal..
IF it is allot - and smokes all the time - it could be that the valve seals need to be replaced OR could be the piston rimgs are shot..
Please dont forget to rate well ;o)
