I've just bought a 57 plate 120d, I'm more than happy with it and had one before. When I put my foot down in a left hand bend the car really tries to lose control. I feel a little wobble. Feels like the rear back suspension..... Also when I put my foot down in a straight line and hit slight bumps in the road it feels like the back bounces and the orange traction light flashes...... I bought the car at a good price and I don't mind spending a little to correct it. I just prefer to know if you guys know what it could be????? I don't want a garage making it up and charging me a fortune......... Thanks
