I bought my 200 last April and so far I've driven 25,000km (15,000 Miles). Recently, I've noticed that the car jerks while changing gears between 40km and 50kmh (30 and 25 mph), when I'm accelerating or decelerating. I took it to my local dealer and they test drove it and told me this is because someone else drove my car, and the gear is relearning your driving patterns (My wife drove it once or twice with me in the car). They informed it would go away after driving it for a while. I drove it for another 2,000 km but the problem is still there.
Any idea why might cause it? I cannot explain in words what it does, but when it changes gears at it pushes the car pushes itself forward then the gear kicks in and grabs it, plus it sounds like a bang.
If anyone can point me in the direction of the solution, I might be able to let the local mechanic look at it!
Thank you in advance.
