Help !!! Just got into my cars and the warnings DBC failure and DSC failure have popped up in the sat nav screen, car is driving as normal and seems fine, any ideas ? Last week I had the steering column and electro mag steering lock replaced, any connection ? Don't want to get ripped off again by the "stealers"

Will let you know, mechanic having a good look this week, thanks

Hello everyone, Has any one got an answer to this problem, at speeds between 40 and 60ish i get a growling noise and vibrating feeling which gets louder and feels like it is travelling through the floor of the car, it gets louder when decellerating too, i have a 320d 55 plate automatic, any ideas ? thanks all.
