206GTİ Gas Pump Does Not Turn Off

I am new to friends, I have a 2001 model gti vehicle. I have a gas pump problem that no one has ever heard of. After I parked my car and switched off the ignition, the sound of the gas pump is constantly coming, as well as the medicine, medicine and medicine sound, as if sending something. I lock my car, but the sound is still coming. My vehicle has been in the industry for 4 days, I can end this sound by removing the battery terminal, but nobody has heard about it, but I have researched so much, but nobody knows. Gasoline pump failure is great but it is strange to hear that sound even if you close the car. Does anyone come to the press before

First of all welcome, in order to get better help;

A strange phenomenon, or trouble, may also arise from electrical chassis connections. fuse box may be oxidized. I think it should be dismantled and checked.

It continues to receive electricity from one place. As a result, the brain continues to receive electricity unless you remove the battery. But it has to turn off the gas pump. It could be from the brain, it could be from insurance It is necessary to make certain trial and error about the electrical parts. As your friend said, it is wise to start from the Insurance box.

Is there anything in the audio installation, lpg or add-on later. There is probably something wrong with the electrical installation. If everything is normal, there may be a problem in the vehicle brain.
