How to open a Volkswagen Polo sedan gas tank hatch

It has long been out of fashion for intruders to quietly drain gasoline from a Zhiguli at night. The age of advanced automotive electronics is coming down the throat of criminal elements. And it is not only about difficulty of “obtaining” minerals from the bowels of the petrol tank, but also about access to the target of interest. First of all, it is a central lock, blocking not only the car doors, but also the vault with fuel.

Nowadays, practically every foreign car is equipped with it. One parked the car, clicked the button on the remote control, and the mechanism worked at once. When you get to the gas station, you unblock it with the same push, and the hatch opens. Some “foreigners” even flaunt modern drive, which automatically unlocks the flap when you enter the gas station.

Causes of the flap locking

The Volkswagen Polo sedan has a classic gas tank hatch, which works perfectly in tandem with the central locking system. Activation of the lock locks the “flap” as well as pressing the driver’s door closing button. A similar principle is characteristic of other relatives of the “European” – Golf and Passat. Czech Skoda also have a similar scheme of the gas tank hatch.

Unfortunately, not all owners of Kaluga sedan know about similar “chip”. As a result, desperate drivers bring their “iron horse” with a broken actuator to a dealer and pay hefty money for the device repair. Experienced drivers are well aware of the little secret of Kaluga masters and know how to “bypass” the inconvenient protection of the central locking system.

The culprit of all small troubles is a notorious drive, blocking a gas tank hatch. It is enough to switch it off manually and the sedan owner’s life becomes much easier.

However, the catch may be in something else. One of the main sources of troubles for many foreign cars is severe winters in our country. The warm-loving and pampered “Europeans” can not endure severe climatic conditions of Russia without problems. Though they stuff them with different winter packages.

“Frostbite” of the gas tank hatch lock is a standard situation for Polo sedan. Glass thawers and various silicone greases often help in a difficult moment. As an alternative, to open the lock, you can also apply traditional “Vedeshka” – and what if? It is excellent, if you can find a place to warm up your car. But when a pointer of fuel gauge gets close to zero, there is no choice but to open the lock with improvised means. Naturally, it leads to its damage.
