Why does the Sagitar not move when shifted to D gear?

[LeJack]

The reasons why the Sagitar does not move when shifted to D gear: insufficient transmission fluid or low internal oil pressure. Incorrect gear switch signal. Issues with the shift solenoid valve wiring or the solenoid valve itself. Below is relevant information about the Sagitar: 1. Introduction to the Sagitar: The Sagitar is a joint venture A+ class sedan brand under FAW-Volkswagen. The vehicle was introduced to the Chinese market on April 9, 2006, with its predecessor being the fifth-generation Volkswagen Jetta sedan, positioned as a "German high-performance sedan." 2. Product philosophy of the Sagitar: On March 18, 2019, the all-new Sagitar Long-Wheelbase was launched, achieving comprehensive innovations in design concepts, comfort and safety, and space layout, ushering in a new era for A+ class sedans.

Last time I drove my Sagitar, I also encountered the issue where it wouldn't move in D gear, which was quite a scare. This situation is mostly due to problems with the transmission mechatronic unit or the clutch, a common issue with Volkswagen's dual-clutch transmissions. You can try shifting to R gear to see if reverse works normally. If the car can move in reverse but not forward, it's almost certain that the forward clutch plates are burnt out. Another simple method is to turn off the engine and restart it—sometimes the transmission computer acts up, and a restart can fix it. If restarting doesn’t help, quickly check whether the transmission fluid level is too low or if the fluid has turned black. Many shops nowadays can read fault codes with a computer; if you see a fault code starting with P17, it usually means the mechatronic unit needs repair. Whatever you do, don’t forcefully press the accelerator—my neighbor ruined his transmission by pushing it too hard.

Don't panic if your Sagitar won't move in D gear. Let me teach you some troubleshooting steps. First, turn off the AC completely, press the brake pedal, shift to D gear and wait for 30 seconds. Listen if the engine RPM suddenly increases - this indicates transmission self-check. If RPM remains unchanged, check if the wheels are blocked by debris. Last time my car had a plastic bag tangled around the half-shaft. DSG models should pay special attention to clutch temperature - overheating triggers protection lock. The most troublesome issue is transmission control valve body failure, which requires computer diagnosis of oil pressure data stream. If the wrench warning light appears on dashboard, it's likely a mechatronics unit problem - a used replacement part costs around 3,000-4,000 RMB.

Brand new car won't move in D gear after just 6 months? It might be the anti-theft system mistakenly locking the transmission. Try locking and unlocking the car with the key again. For older cars, check the transmission fluid first - 7-speed dry dual-clutch transmissions need fluid changes every 60,000 km. The most extreme case I've seen was a broken gearshift button spring getting stuck in neutral. Another rare cause: unstable battery voltage can affect the transmission computer. Use a multimeter to check - if battery voltage is below 12V, a jump start will get you moving immediately. Mechanics say loose shift cables in Sagitars can also cause this.
