Hello guys,
I use a 2007 model VW jetta.
I just noticed some days back that while accelerating, my car suddenly jerks violently.
Let me explain better, If the car is at, say 40km/hr and I start accelerating,
when it gets to like 60 it stops increasing speed and starts jerking violently,
if I take my leg a bit away from the pedal and move at constant speed (60km/hr) for about 30 seconds
and then accelerate again it will respond to the acceleration until I get to like 80km/hr and it jerks AGAIN and make a loud sound (GBI) .
and the same cycle occurs at 100km/hr.

Please is there anybody with an idea of what can be going wrong with the car.
Responses will be appreciated.
Thanks

Get the car scanned first. I guess it has issues engaging gears. Has it been worked on before.

Thank you my brother.
I can't really say cos I bought it from someone and the person is not within the country now.
