For your convinience I´ve tried to translate the fault-part into English (excuse my bad translation
"But with a little bit more forced driving we ran into a more serious problem that occured on both of our testcars.A stay (don´t know if this is the right term, (a small arm in the front suspension) (BMW Group Sweden haven´t figured out wich one yet by the front left wheel jumped out of it´s place and made the car bounce all over the place and made the steeringwheel pull hard to the left. Stranger is that the car fixed themselves if you accelrated hard straight forward, BMW Group sweden did not find anything wrong with the car"

Have anyone experienced this problem before, never heard of it, talked to the guy that did the test and he is courious to know if this is a known problem..
