What are the reasons why the Tiguan won't start?

Tiguan may not start due to reasons such as a dead battery, empty fuel tank, incorrect gear position, among others. Detailed reasons why the Tiguan won't start: 1. Dead battery: This could be caused by leaving the headlights on for an extended period leading to battery drain or the battery reaching the end of its lifespan. It is generally recommended to replace the battery every 2 years. Additionally, installing aftermarket audio systems can also affect the battery's lifespan. 2. Incorrect gear position: For automatic transmission vehicles, the gear must be in P (Park) or N (Neutral) position when starting. If the gear is in R (Reverse) or D (Drive), the vehicle won't start. Some manual transmission vehicles may also fail to start if the clutch is not depressed.
I've been driving the Tiguan for many years, and it's quite common to have trouble starting it. The first thing to check is whether the battery is dead. As the car ages, the battery capacity decreases, especially in cold weather or after sitting idle for a long time, making it harder to start. Listen for sounds—if turning the key doesn't elicit any response and you only hear a click, it might be an issue with the starter relay. Also, check if the dashboard lights up when trying to start the car. Dim lights indicate a weak battery. Another possibility is a dead key fob battery, which can trigger the anti-theft system to lock, preventing the signal from reaching the car and causing a no-start. Fuel system issues, like a faulty fuel pump failing to deliver fuel or a clogged fuel filter, should also be checked. I remember once having difficulty starting after rain—it turned out the spark plugs were wet, and cleaning them fixed the issue. My advice is to first try jump-starting the car. If that doesn’t work, consult a mechanic instead of forcing it. Regular maintenance should include monitoring battery health to avoid unexpected problems.
Young car owners, every one of you with a Tiguan, don't panic if it won't start. It's mostly a battery issue—either its lifespan is up or it's undercharged. Check the dashboard; if the lights are flashing, it means the circuit is intact, and the problem might just be insufficient power. Weak key fob batteries are also common, especially when the remote isn't working properly—try replacing the battery. Under the hood, check the fuses; a blown fuse can interrupt the circuit. On the fuel side, a stuck fuel pump or clogged injector can cut off fuel supply, especially when carbon buildup is severe—clean them promptly. Cold weather is often the culprit, so try warming it up before starting. For a simple DIY fix, use a multimeter to check the battery voltage; if it's below 12V, the issue is pretty much confirmed. Don’t forget the steering lock system—activated anti-theft features can also prevent starting. If all else fails, head to a repair shop for a proper diagnosis—safety first.
