Hi, I bought my Mercedes c class, 1 year ago 2013 plate, AMG sport automatic. Was returned to me after having the bumper repaired. But now the car judders and when shifts gears shakes. I was going up a hill the other day and the car completely stopped working and had to roll it onto level road before started working again. I suspect that there may be a transmission issue. Surprised as only got 45000miles on the clock and mainly use it for school runs. Not sure how to go about resolving the issue, will hand it in for diagnostic at Mercedes garage, but was wandering what people thought?
