The reason why the Volkswagen Sagitar does not move when in D gear without pressing the accelerator is that the engine's throttle opening is too small, and the fuel injector's fuel supply is insufficient. Taking the Sagitar 2021 200TSI Manual Fashion Smart Connect Edition as an example: The manufacturer of this car is FAW-Volkswagen, the intake form is a compact car, the energy type is gasoline, and the transmission is a 5-speed manual. The car's length, width, and height are 4753mm, 1800mm, and 1462mm respectively, with a wheelbase of 2731mm. The body type is a 4-door, 5-seater sedan, the intake form is turbocharged, the drive mode is front-wheel drive, the power steering type is electric power steering, and the body structure is a unibody.
I've been driving this Volkswagen Sagitar for about seven or eight years, and recently encountered an issue where it won't move in D gear without giving it gas, which is quite annoying. At first, I thought it was an engine problem, but after some research, I found out it's actually an issue with the transmission's idle control, likely caused by insufficient oil pressure or aging sensors. These Volkswagen automatic transmissions are most prone to acting up during cold starts, as the oil pump might be slow to build pressure, resulting in poor power transfer. I checked the transmission fluid myself and found it was a bit low; topping it up helped slightly. However, prolonged issues like this can damage the clutch plates, so I recommend regular transmission fluid changes, especially for older cars. Safety first—if you run into this kind of problem, don't force it; get it diagnosed with a fault code scan at a professional shop as soon as possible.
