What is the reason why the 2015 Passat does not move when shifted to D gear and given throttle?
2 Answers
2015 Passat does not move when shifted to D gear and given throttle for the following reasons: Transmission sensor error: When the gear shift valve position sensor signal is incorrect, it cannot detect which gear the car is in. Generally, cars that use automatic transmission (AT) to regulate speed rely on the control system of the automatic transmission to automatically select the appropriate gear based on engine speed and load during driving, replacing the driver's subjective judgment of timing and gear shifting operations. Shift valve problem: If there is an issue with the shift valve, the gear may not engage properly, and the oil passage may not open. Automatic transmission cars usually use hydraulic transmission devices to replace the mechanical clutch of manual transmission cars, so there is no clutch pedal.
I've been driving for over ten years and encountered many similar situations. The 2015 Passat not moving when accelerating in D gear is most commonly a transmission issue, such as clutch plate wear causing gear slippage or insufficient oil pressure making shifting difficult. Volkswagen's DSG design is prone to such failures. It could also be the handbrake not fully released or the electronic parking system stuck, making the car think it's still in brake mode. Additionally, check if the engine has insufficient power output, like spark plug or fuel supply problems. My experience is to gently repeat the gear shifting operation first to ensure proper engagement, then check the dashboard for any warning lights. Safety cannot be ignored—if the car doesn't move, pull over immediately to avoid further damage by continuing to test drive. Regular transmission fluid changes can prevent such issues. Simple maintenance can save big money.
