The reasons why a Volkswagen Jetta won't start are: 1. Mechanical failure; 2. Engine carbon buildup; 3. Steering wheel lock; 4. Water in the engine; 5. Dead battery; 6. Incorrect gear position; 7. Spark plug failure; 8. Electrical circuit failure; 9. Fuel filter failure. Taking the 2019 Jetta VS5 as an example, its body structure is a 5-door, 5-seat SUV with body dimensions of: length 4419 mm, width 1841 mm, height 1616 mm, wheelbase 2630 mm, and fuel tank capacity of 51 liters. The 2019 Jetta VS5 is equipped with a 1.4T turbocharged engine, with a maximum power of 110 kW and a maximum torque of 250 Nm, paired with a 5-speed manual transmission.
I've been driving a Jetta for ten years, and the most common reason for it not starting is battery issues, especially in cold winters when the battery voltage is too low, requiring more current to start, making it prone to stalling. The last time I encountered this issue, it was due to corroded battery terminals; cleaning them fixed the problem. Secondly, a worn-out starter can also cause no response—if there's no sound when turning the key, it needs replacement. Then there's the fuel system, such as a faulty fuel pump or clogged filter, where the engine cranks but doesn't start. I recommend regularly checking the battery's health, using a voltmeter to test it, and keeping it charged. Volkswagen parts are highly interchangeable, so replacement costs aren't high, but neglecting repairs can lead to bigger losses, like a completely dead battery, which makes towing fees expensive. Wear gloves for safety before working on it—don't skimp on small expenses and risk bigger losses.
