Mine got replaced 2 months ago (OG 07/18)... It is NOT going to go away, just will get worse and worse.
They charged me 1345 Euros (BMW paid 40 percent of that amount). 2 months out of warranty.
The dealer tried the software update. Didn't help... But it did provide much better steering and a lot more awesome wheelspin off the line (tail happy+)! Great upgrade!!! No, fantastic upgrade!!!
