im writing cause im having an issue with my 2006 bmw m5. it recently started giving me all kinds of malfunctions dsc,dbc,ftm,parking brake,engine, seems everytime i try to pick up speed at around 80mph they all light up. then i turn the car off and then on and they go away until i try to pick up seed again.can this be a software issue or the steering angle sensor aka szl optican sensor. thanks john c
