I owned a BMW X3 20d 2005 (100000km) and the problem is that lately a cloud of blue smoke gets out during start up!!! not a´lways but often.. the smoke lats 2 min and then nothing on the road...
if i stop somewhere for around ten min the smoke come back when i drive back..
I have no idea what is going on... i dont see any leaks of oil or something like this..i am very confused..
please give me an advise if you have seen something like this on your X3!!
thanks a lot..
