Jetta hot cars don't catch fire easily. What happened?

The poor ignition of Jetta hot car may be caused by excessive carbon deposition in the throttle, idle motor or air inlet. Due to too much carbon and dirt deposited in the air inlet, the cross-sectional area of the air passage changes, which makes the control unit unable to accurately control the idle intake, resulting in too rich or too lean mixture, abnormal combustion, engine jitter, and even failure to start after starting.

Or the fuel injector leaks slightly, which may cause the fuel to leak into the combustion chamber for a period of time after the vehicle is turned off, and the mixture is too rich when it is restarted, and it is difficult to start at last. The activated carbon canister may also be damaged. If the solenoid valve is always on, the mixture at the engine intake will always be rich, which will cause the phenomenon that the mixture is too rich to start when the engine is hot. According to the above analysis, it is recommended to conduct on-site inspection.

Jetta took the lead in applying the world's most advanced 5-valve multi-point injection engine in China. With its unique product design performance and all-round safety technical equipment, Jetta series cars have a distinctive product personality. Jetta not only took the lead in applying high-grade engine technology and safety technology and equipment to mid-range family cars, but also took the lead in adopting advanced multi-point injection technology in all products, and all of them were equipped with three-way catalytic reactors, which improved the environmental performance of mid-range cars, thus making Jetta an environmental pioneer of mid-range cars.
