My Mercedes Gla no longer accelerates smoothly because of the injectors:

Let’s concentrate on the trouble with the injectors in your Mercedes Gla. If you have the feeling that your car is sputtering, that it endures a loss of power, it is quite possible that because of a bad fuel quality one or more of your injectors have obstructed or congested, which results in a bad air/fuel mixture sent to the engine and which will as a result consequentially disturb its normal performance, do not forget to verify the condition of your injectors.

My Mercedes Gla no longer accelerate because of the clutch:

One of the common triggers of a Mercedes Gla not accelerating when hitting the gas pedal, or not moving forward, is that your clutch disc is outdated. The truth is, the task of the clutch is to transmit the power from the engine to the gearbox which will then transmit it to the wheels. If this disc is “smooth”, you will no longer be able to transmit this power to the wheels and you will discover that your Mercedes Gla no longer accelerates, or at least, the engine may rev up, but the speed of your car will have difficulty raising.
