My car is suffering from a loss of power and kind of jumps when the speed is consistent. If I accelerate the car is fine. I have no engine lights on. I have taken it to a garage and they say could just be dpf but they are unsure.

Hello,

This could be a problem with your throttle body needing to be cleaned. Over time when moving the volumes of air that your vehicle's throttle body does, it collects a black gunk that will confuse the Throttle Position Sensor (TPS) and could cause it to go into limp mode. Here is a link below for you to go to explaining everything in more detail:
